7	- Jones
8	- PIE Tree
9	- Questions
10	
11	- How to reconstruct:
12	  - There are rules
13	  - They go forward
14	  - Run them backward:
15	    - What language could have evolved into both of these
16	      given the known rules
17	- Where do forward rules come from?
18	  - Which languages are related?
19	    - Cognate sets
20	      - [[https://youtu.be/p7ppktfdNCk?si=cVzJvkI9KycYW9jf&t=145][Clip from here]]
21	      - Swadesh list [screenshot]
22	    - Which languages are related challenge [screenshot]
23	  - Find correspondence sets
24	  - Posit proto sounds
25	  - Two steps:
26	    - Do easy cases first [screenshot?]
27	    - Then hard cases
28	    - Majority rules
29	    - Occam's Razor
30	    - Example cher/karo/karo/karu (dear in French, Italian, Spanish,
31	      Portuguese)
32	      - *karo = proto-word by majority rules
33	      - 2/4 is a majority if the remaining are different
34	      - * indicates reconstructed
35	    - Sometimes there isn't a majority and you have to figure out
36	      which of the two came first. And for that, look at other words
37	      and see which makes more sense across the dataset
38	      - XXX: Example of this
39	
40	- Directionality of changes
41	  - Assimilation
42	  - Degemination
43	  - Lengthening of vowel
44	  - Lenition: Weakening of a consonant from one that takes more effort to
45	    pronounce to less. Stop becomes an affricate or fricative.
46	  - Sandhi: Conditioned changes at word boundaries. English example: loss
47	    of "i" in "is". "Frank is" becomes "Frank's"
48	
49	
50	- Where's the Proof:
51	  - Hittite
52	  - Records
53	  - Archaeology: 
54	    - Linguistics forced archaeology:
55	      - Settlement archaeology!
56	      - Linguistic reconstruction happened first and then the archaeologists
57	        tried to find evidence of cultures fitting the language tree. Also
58	        known as settlement archaeology
59	      - XXX: Examples here
60	
61	- Dravidian
62	  - Stuff
63	
64	
65	
66	- When there is no rule, it came from another language!
67	
68	- Reconstructing an older form:
69	  - First determine forward change rules
70	  - Then use those to work backwards
71	
72	- Forward change rules:    
73	  - Correspondence sets
74	
75	
76	
77	
78	
79	*** Motivating examples
80	- Indian / European similarities
81	  - XXX: examples
82	- Indian / Persian similarities
83	  - XXX: examples
84	
85	*** Early Signs
86	- Florence merchant in Goa 1580s, Filippo Sassetti, noticed Sanskrit
87	  sarpa resembled Italian serpe, deva resembled dio, and the numerals
88	  six, seven, eight looked nearly identical
89	- Jones:
90	  - What did Jones see?
91	    - Sanskrit pitṛ / Greek patēr / Latin pater / Old English fæder
92	    - Sanskrit trayas / Greek treis / Latin trēs / English three
93	    - XXX: more examples
94	  - "common source, which, perhaps, no longer exists."
95	
96	*** From coincidences to systems
97	- Where Latin has p, native English vocabulary consistently has f:
98	  pater/father, piscis/fish, pēs/foot, plēnus/full, prō/for.
99	- Where Latin has k (written c), English has h: centum/hundred,
100	  cor/heart, canis/hound, caput/head.
101	- Grimm's Law
102	- Nine consonant shifts
103	  - XXX: list all 9 with examples
104	
105	**** Neogrammarian principle: sound laws have no exceptions
106	- Verner's Law (move to overflow)
107	
108	**** Borrowing:
109	- "schedule" doesn't follow Grimm's law (because it entered via Latin/French)
110	- Hindi kitāb (Arabic loan) vs pustak (via Sanskrit).
111	- Tamil: putthakam (via Sanskrit) vs native ēṭu.
112	- Mama-papa: universal
113	
114	*** Laryngeal Triumph: Science = Prediction
115	- Saussure (1879): PIE must have had "lost segments", not found in any daughter language,
116	  - Saussure predicted: *peh₂s- 
117	    - Latin: pāscō (the laryngeal is gone, but it left the vowel long)
118	  - Hittite (1915): Found h exactly where predicted
119	    - — Hittite: paḫš- (the laryngeal is visible)
120	
121	*** Family Tree
122	- 1860s
123	- Shared innovation: only valid grouping criterion
124	  - shared retentions = prove nothing
125	- centum/satem split = ?
126	- Anatolian = first branch to break off
127	- Tocharian
128	
129	*** Culture and archaeology  
130	- PIE words: wheel, axle, yoke, wool, horse, honey, bee.
131	  - wheel
132	    - time = after wheel was invented (4th millennium BCE)
133	    - place = where horses were domesticated (Yamnaya)
134	  - 3500 to 3000 BCE
135	
136	*** ablaut
137	- The famous e / o / zero ablaut you see in English sing/sang/sung is
138	  a direct inheritance from PIE, and you see the same pattern in Greek
139	  leíp-ō / lé-loip-a / é-lip-on ("I leave / I have left / I left"). We
140	  can even reconstruct poetic formulas: imperishable fame survives as
141	  Greek kléos áphthiton and Vedic śravas akṣitam — almost certainly
142	  the same phrase, sung by Indo-European bards before the daughter
143	  languages parted.
144	  - XXX: explain this "poem"
145	
146	*** PII (2500-2000 BCE)
147	- The satem shift
148	  - PIE *k̑m̥tóm = hundred
149	    - Sanskrit śatam, Avestan satəm, Old Persian θata, Modern Persian sad, Hindi sau.
150	      - palatovelar *k̑ becomes a sibilant ś
151	    - Latin centum, Greek hekatón, English hundred.
152	
153	- Vowel merger:
154	  - PIE had a distinct *e, *o, *a. Indo-Iranian merges all three into *a.
155	  - Greek pherō / Latin ferō / Sanskrit bharā́mi "I carry"
156	
157	- RUKI rule:
158	  - PIE *s becomes *š (later Sanskrit ṣ) after r, u, k, i. So PIE
159	    *nisdós "nest" gives Sanskrit nīḍa.
160	- Brugmann's Law:
161	  - PIE *o in open syllables lengthens to PII *ā. PIE *bʰórom → Sanskrit bhāram "load."
162	
163	**** Indo Aryan Split (1800BCE)
164	- Split:
165	  - India: Vedic Sanskrit -> Classical Sanskrit -> Prakrits -> Hindi/Marathi/etc
166	    - (Dravidian: covered later)
167	  - Iran: Avestan (1000BCE) -> Old Persian (6th-4th c BCE) -> Middle
168	    Persian -> Modern Persian/Farsi/Dari/Tajik
169	
170	- Small but very systematic divergences
171	  - PII *s → Iranian h
172	    - sapta "seven" / Avestan hapta / Old Persian hafta / Modern Persian haft
173	    - Sanskrit soma / Avestan haoma
174	    - Sanskrit Sindhu (the river) / Old Persian Hindu — and from
175	      Persian Hindu the Greeks got Indos and we got India and Hindu.
176	    - XXX: more examples
177	  - Iranian removes aspiration from *bʰ, *dʰ  → *gʰ b, d, g
178	    - Sanskrit preserves: bhrātar / Avestan brātar / Persian barādar "brother."
179	  - PII *ś (from PIE *k̑) + v → Iranian sp.
180	    - Sanskrit aśva "horse" / Avestan aspa / Old Persian asa / Modern Persian asb
181	    - XXX: more examples
182	  - The deva/daeva inversion.
183	    - PIE *deywós "celestial, god" → Sanskrit deva "god" but Avestan daēva "demon
184	      - Sanskrit asura (lord in Rigveda; but demon later) / Avestan ahura
185	
186	**** Vedic Sanskrit to Classical Sanskrit
187	- Vedic Sanskrit: messy, freer syntax; more verbal forms; pitch/accent
188	- Classical Sanskrit: Pāṇini's Aṣṭādhyāyī (~5th c. BCE)
189	  
190	***** Sanskrit to Prakrits
191	- Regional "natural" regular-people languages:
192	  - Māhārāṣṭrī (ancestor of Marathi/Konkani)
193	  - Śaurasenī (Hindi belt)
194	  - Māgadhī (Bengali, Odia, Assamese, Bihari)
195	  - Ardha-Māgadhī (Jain canon: XXX: wut?)
196	  - Pali (Theravāda Buddhism — essentially a Western Prakrit)
197	- Simplification!!!
198	  - Simplify clusters
199	    - gemination = consonant doubling via assimilation
200	      - the second wins, first becomes a copy
201	        - Why? Easier to articulate.
202	      - the weaker consonant becomes a copy of the stronger? (XXX: wut?)
203	      - (Gemini = Twins)
204	  - Intervocalic consonants weaken (XXX: wut?)
205	  - vowels assimilate
206	  - degemination!
207	    - with compensatory lengthening of the preceding vowel
208	    - 
209	
210	- Examples:
211	  - Sanskrit sapta → Pali satta → Hindi sāt "seven"
212	  - Sanskrit hasta "hand" → Prakrit hattha → Hindi hāth / Marathi hāt
213	  - Sanskrit karma → Prakrit kamma → Hindi kām "work"
214	  - Sanskrit agni "fire" → Prakrit aggi → Hindi āg
215	  - Sanskrit dugdha "milk" → Prakrit duddha → Hindi dūdh
216	  - Sanskrit akṣi "eye" → Prakrit acchi → Hindi ā̃kh 
217	  - Sanskrit mātṛ → Prakrit mātā → Hindi mā, Marathi māy
218	  - sarpa -> sappa -> sāp 
219	  - karṇa → kaṇṇa -> kān
220	
221	  - Latin -> Italian → Spanish similar: Latin noctem → Italian notte → Spanish noche
222	  - 
223	
224	- What's in a name
225	  -  PIE *h₁nómn̥
226	    - Proto-Indo-Iranian *Hnā́ma
227	      - Sanskrit nā́ma → Pali nāma → Hindi/Marathi nām
228	      - Avestan nąman → Old Persian nāma → Middle Persian nām → Modern Persian nām
229	    - Latin nōmen
230	      - Greek ónoma, English name
231	
232	*** Dravidian
233	- AASI, ASI, ANI, IVC
234	- Dravidian, Munda: older languages: substrate (=gone now, since 1500BCE)
235	- Sanskrit:
236	  - Already different from PII because of Dravidian influence
237	  - Retroflexes (ṭ, ḍ, ṇ, ṣ)
238	    - Not in PIE, not in Latin->French/German/English, not in PII/Iranian
239	    - In Sanskrit since Rigveda
240	    - Dravidian: native
241	      - Tamil paṭu "to lie down" vs patu "ten"
242	      - Tamil kāṭu "forest" vs kātu "ear."
243	    - Two types of retroflexes in Sanskrit:
244	      - Internal changes = RUKI rule
245	        - PIE *s becoming ṣ after r, u, k, i — the RUKI rule
246	      - But many appear in words where no internal rule predicts them,
247	        and notably in words for things culturally Indian.
248	        - Explanation? Dravidian loanwords
249	        - Compare Sanskrit aṣṭa "eight" with Avestan ašta, Greek októ,
250	          Latin octō. Sanskrit alone went retroflex. 
251	  - Loanwords:
252	    - Sanskrit kuṭa "hut," kuṭi "house" / Tamil kuṭi "dwelling, household"
253	    - Sanskrit mīna "fish" / Tamil mīn "fish, star"
254	    - Sanskrit daṇḍa "stick, staff" / Tamil taṇṭu "stalk"
255	    - Sanskrit nīra "water" / Tamil nīr "water"
256	    - Sanskrit mukha "face/mouth" (debated) / Tamil mukam
257	    - Sanskrit bala "strength" / Tamil val "strong"
258	    - Sanskrit phala "fruit" (debated) / Tamil paḻam
259	
260	**** Syntactic Dravidian Features in Sanskrit
261	- SOV:
262	  - Indian:
263	    - Hindi: rām-ne mohan-ko kitāb dī
264	    - Tamil: rāmaṉ mōhaṉukku puttakam koṭuttāṉ
265	  - Others:
266	    - Spanish: Ramón le dio el libro a Mohan
267	    - French: Ramon a donné le livre à Mohan 
268	    - Russian: Ramon dal Mohanu knigu
269	    - Persian: Rāmān be Mohan ketāb dād
270	
271	  - PIE was probably partially SOV; Classical Latin was SOV; Old Persian is SOV
272	    - But all shifted:
273	      - All modern European languages: partly or fully SVO
274	      - Modern Persian: lots of flexibility
275	      - Vedic Sanskrit allowed SV VS other patterns
276	    - But Classical Sanskrit = SOV; all later languages rigidly SOV
277	      - Because of Dravidian influence
278	
279	- Quotative constructions
280	  - He said *that* he would come.
281	    - Complementizer before the quoted material
282	  - Tamil:
283	    - avaṉ "nāṉ varukirēṉ" *eṉṟu* coṉṉāṉ
284	      - Kannada: anta / endu; Telugu: ani. Malayalam: ennu
285	  - Sanskrit:
286	    - sa "ahaṃ gacchāmi" *iti* abravīt
287	  - Hindi:
288	    - us-ne kahā *ki* "mai̐ jā rahā hū̐"
289	  - Marathi:
290	    - to mhaṇālā ki "mī yetō"
291	    - to mhaṇālā "mī yetō" *mhaṇūn*
292	  - Bengali:
293	    - se bollo *je* "āmi jacchi"
294	    - se "āmi jacchi" *bole* bollo
295	  - Nepali, Assamese, Sinhala — all have a quotative derived from
296	    "say" placed after the quoted material, parallel to Dravidian.
297	
298	- Echo reduplication (needs validation)
299	  - Hindi: chāy-vāy, kitāb-vitāb, pānī-vānī
300	  - Tamil: tēṉīr-kīṉīr, puttakam-kittakam
301	  - Kannada: chahā-gihā, pustaka-gistaka
302	  - Marathi: chahā-bihā, pustak-bistak
303	  - Bengali: chā-ṭā
304	  - Telugu: ṭī-gīṭī
305	  - Nowhere else in the world except Turkish:
306	    - English has: partial reduplication (zig-zag, flip-flop, ding-dong, criss-cross)
307	    - Also: fancy-schmancy: uncommon; from Yiddish; and meaning is different
308	
309	- Dative subjects for experiencers
310	  - Hindi mujhe bhūkh lagī hai "to-me hunger is felt" = "I'm hungry."
311	    - Compare Tamil eṉakku paci "to-me hunger."
312	    - Other IE languages use nominative subjects: French j'ai faim
313	    - German ich habe Hunger
314	
315	
316	- Conjunctive participles
317	  - Hindi: ghar jā-kar khānā khā-yā
318	    - uṭh-kar, muh dho-kar, kapṛe pahan-kar, ghar se nikal-kar, bus pakaṛ-kar daftar pahũcā
319	  - Tamil: vīṭṭukku pōy cāppiṭṭēṉ
320	    - eḻuntu, mukam kaḻuvi, uṭai aṇintu, vīṭṭiliruntu puṟappaṭṭu, basil ēṟi, alavalakam cērntēṉ
321	  - English: Having gone home, I ate
322	    - Having-gotten-up, having-washed-face, having-worn-clothes,
323	      having-left-house, having-caught-bus, reached office
324	  - In Western languages: this is uncommon and rare. In Sanskrit, it
325	    is one among multiple options. In Hindi/Tamil: it is the default way of speaking
326	
327	
328	*** Dating
329	- Hard dates:
330	  - Modern: DNA (201x)
331	  - Earlier written records (still surviving or archaeology)
332	    - Old Persian: Behistun inscription, ~520 BCE (Darius I). Firm date.
333	    - Hittite: cuneiform tablets, ~1650–1200 BCE.
334	    - Mycenaean Greek: Linear B tablets, ~1400–1200 BCE.
335	    - The first written Sanskrit is Ashokan-era, 3rd c. BCE
336	      - But most likely vedic Sanskrit = the Rigveda = ~1500–1200 BCE
337	    - Latin: earliest inscriptions ~600 BCE.
338	- Relative dating
339	  - Layered sound changes
340	    - Sanskrit sapta → Prakrit satta → Hindi sāt.
341	      - Two changes:
342	        - #1: The cluster simplification (pt → tt)
343	        - #2: degemination (tt → t) and vowel lengthening
344	      - #1 must come before #2... can't get sāt directly from sapta
345	  - Another example:
346	    - Iranian, s → h
347	      Must be after Sanskrit split (2000BCE)
348	      - Because Sanskrit kept the s
349	      - But before Old Persian which already shows h in hafta: (600BCE)
350	
351	- Borrowed words freeze at time of borrowing:
352	  - Finnish kuningas "king" was borrowed from Proto-Germanic *kuningaz.
353	    - But Germanic itself has moved on (English king, German König).
354	    - So the borrowing happened before Germanic underwent its later changes
355	  - Sanskrit loans into Dravidian, and Dravidian loans into Sanskrit,
356	    can be dated by which sound-change stage of each language the loan
357	    reflects. If a Tamil word shows up in Sanskrit in its Old Tamil
358	    form rather than its Middle Tamil form, the contact predates the
359	    Middle Tamil shift. (XXX: examples)
360	    
361	- Mitanni treaty:
362	  - The Mitanni treaty (~1380 BCE, in northern Syria) contains
363	    Indo-Aryan god-names (Mitra, Varuna, Indra, Nasatya) and
364	    horse-training terms (aika- "one," tera- "three," panza- "five,"
365	    satta- "seven," nava- "nine"). These forms are more archaic than
366	    Vedic — aika is older than Sanskrit eka; satta shows the
367	    assimilation Vedic sapta doesn't. This single document proves
368	    Indo-Aryan existed as a distinct branch by 1400 BCE, and that one
369	    offshoot had already drifted west.
370	
371	- Linguistics + Archaeology:
372	  - PIE has solid reconstructions for wheel (*kʷékʷlos), axle
373	    (*h₂eks-), yoke (*yugóm), wagon/wain, and horse (*h₁éḱwos).
374	    Wheeled vehicles appear in the archaeological record around 3500
375	    BCE. So PIE can't be much older than that, or the speakers would
376	    have split before inventing wagons, and you wouldn't get the same
377	    word across all branches. This argument — developed by Anthony,
378	    Mallory, and others — placed PIE at roughly 4000–3000 BCE long
379	    before ancient DNA confirmed it.
380	
381	  - Conversely, PIE has no reconstructible word for iron (each branch
382	    has its own), placing the breakup before the Iron Age (~1200 BCE).
383	
384	  - And reconstructed words for bee and honey (*médʰu) but not for
385	    typical Mediterranean or tropical species suggest a temperate
386	    homeland.
387	
388	  - For Indo-Iranian specifically: shared vocabulary for chariot
389	    (*rátʰas), spoke, horse-training, dates the common period to after
390	    the spoked-wheel chariot appears (Sintashta culture, ~2000 BCE) —
391	    which matched the linguistic estimate well.
392	
393	- Convergence of 4 methods:
394	  - relative chronology
395	  - paleontology
396	  - loanword stratigraphy
397	  - archaeology
398	
399	*** Why Simplification:
400	- Small populations = increasing complexity
401	- Increasing population (conquest/administration, trade, religion) = simplification
402	
403	
404	
405	* Abstract
406	"Proto Indo European: The Mother of All Languages"
407	
408	How do we know so much about a language of which zero records survive? The Latin word for "father" is "pater": How do we know both are descended from PIE word "*ph₂tḗr" and more importantly, why was the the original `p` based and not `f` based? How do we know that Sanskrit is descended from PIE and not the other way round?
409	
410	I'll talk about the science behind the reconstruction of PIE and other interesting facts about the PIE language family tree.

Perfect! I found the exact passage you're looking for. In his 1786 presidential address to the Asiatic Society, William Jones announced that "the Sanscrit language … bear[s to GREEK and LATIN] a stronger affinity, both in the roots of verbs, and in the forms of grammar, than could possibly have been produced by accident; so strong indeed, that no philologer could examine them all three, without believing them to have sprung from some common source, which, perhaps, no longer exists."

This statement came in his Third Anniversary Discourse to the Asiatic Society in 1786, in which he suggested that Sanskrit, Greek and Latin languages had a common root, and that they might all be further related to Gothic and Celtic languages, as well as to Persian.

Based on the search results, here's what I found about the topic you searched for:

## Saussure's Laryngeal Theory

Ferdinand de Saussure first proposed the laryngeal theory in 1879 to explain apparent irregularities in morphophonological patterns in daughter languages. More specifically, Saussure first suggested in 1878 that consonants had disappeared in the Indo-European dialects, leaving reflexes in lengthened vowels. Saussure's observations did not achieve general acceptance, as they were still too abstract and had little direct evidence to back them up.

## Kurylowicz's 1927 Confirmation

In 1927, Polish linguist Jerzy Kuryłowicz discovered that a sound transcribed as ḫ in the newly deciphered ancient Indo-European Hittite language appears in many of the places that the laryngeal theory predicted. In his work "The Indo-European ə and the Hittite ḫ", Kuryłowicz demonstrated that where de Saussure had postulated the presence of lost a-rounding and o-rounding consonants, Hittite preserved a distinct phoneme represented by the letter ḫ.

This discovery was crucial because Saussure's assumption has been upheld by the discovery of confirming evidence in Hittite. De Saussure had passed away 14 years earlier and could not witness the validation of his theory.

Here are the search results for your query about the Mitanni treaty and Indo-Aryan connections:

## Mitanni Treaty (1380 BCE) and Indo-Aryan Gods

In a treaty between the Hittites and Mitanni (between Suppiluliuma I and Shattiwaza, c. 1380 BC), the deities Mitra, Varuna, Indra, and Nasatya (Ashvins) are invoked. These deities are familiar from the Rigveda: Mitra – guardian of contracts, Varuṇa – enforcer of cosmic order, Indra – storm-god, slayer of Vṛta, patron of warriors, and Nasatyas – divine twins, healers, and rescuers.

## Kikkuli's Horse Training Manual

Kikkuli's horse training text (circa 1400 BC) includes technical terms such as aika (Vedic Sanskrit eka, one), tera (tri, three), panza (pañca, five), satta (sapta, seven), na (nava, nine), vartana (vartana, round).

## Indo-Aryan Superstrate Evidence

Some theonyms, proper names and other terminology of the Mitanni exhibit close similarities to Indo-Aryan, suggesting that an Indo-Aryan elite imposed itself over the Hurrian population in the course of the Indo-Aryan expansion.

The presence of these Vedic deities' names and Sanskrit-based numerals in Mitanni documents has been significant evidence in scholarly discussions about Indo-Aryan linguistic and cultural expansion in the ancient Near East during the 2nd millennium BCE.

## Filippo Sassetti and Sanskrit-Italian Language Similarities

Filippo Sassetti (1540–1588) was a traveller and merchant from a long-established Florentine mercantile family, who was born in Florence in 1540. He travelled to the Indian subcontinent, reaching Cochin in November 1583, and remained in Cochin and Goa and the Malabar coast that joins the two, until his death.

Writing privately to fellow Florentine Bernardo Davanzati in 1585, he noted some word similarities between Sanskrit and Italian (e.g. deva/dio 'God', sarpa/serpe 'snake', sapta/sette 'seven', ashta/otto 'eight', nava/nove 'nine').

He is known to posterity from the thirty-two detailed letters he sent home to members of the Florentine patriciate and the Grand Duke of Tuscany; they were not published until centuries after his death. This unpublished observation is today credited to have foreshadowed the later discovery of the Indo-European language family.

Sassetti died in Goa, India in 1588.

I've completed the web search for your query. Here are the results:

The search returned several relevant sources discussing Proto-Indo-European wheel terminology and its reconstruction. Key findings include:

Proto-Indo-Europeans were familiar with wheeled vehicles as they knew the wheel (*kʷekʷlóm), the axle (*h₂eḱs-), the shaft, and the yoke (*yugóm).

The reconstructable PIE form is *kwékwlo-s, derived from *kwel- meaning 'turn'.

The sources reference both Mallory and Adams as key scholars in this field. Mallory and Adams show how scholars have reconstructed Proto-Indo-European from its descendant languages, and Mallory and Adams authored the Encyclopedia of Indo-European Culture.

Cognates for wheel and wagon terms occur in all major branches of Indo-European, from Celtic in the west to Vedic Sanskrit and Tocharian in the east, and from Baltic in the north to Greek in the south.

The search results confirm the importance of wheel and wagon terminology in understanding Proto-Indo-European society and its technological capabilities, which scholars like Mallory and Adams have extensively documented.

Based on the search results, here's information about the Indo-Hittite hypothesis and related topics:

## The Indo-Hittite Hypothesis

The Indo-Hittite hypothesis, formulated by Edgar Howard Sturtevant in 1926, proposes that the Anatolian languages split off from a Pre-Proto-Indo-European language considerably earlier than the separation of the remaining Indo-European languages. Sturtevant advanced this hypothesis in his 1933 work "A Comparative Grammar of the Hittite Language," positing that Anatolian languages like Hittite represented an early divergence from a pre-Proto-Indo-European stage, thus anchoring the family's roots in Anatolia.

## Key Supporting Evidence

According to Sturtevant, this theory was based upon the observation that the Anatolian branch contained a number of very archaic features that set it apart from other daughter languages as a group, leading him to conclude that the Anatolian branch must have become separated from the main speech community before the other branches came into being.

## Modern Status

Nowadays the majority of scholars seem to support the hypothesis that Anatolian did split off first from the mother language, and that the other branches at that point in time still formed a single language community that underwent some common innovations that Anatolian did not share.

The search results do not contain specific information about the relationship between Tocharian and the centum classification that you mentioned in your query.

I've performed the web search for you. Here are the key findings:

## Search Results Summary

The search returned extensive information about this important Indo-European poetic formula. Here are the main points:

**The Phrase and Its Meaning:**
The poetic language preserves in Greek and Vedic one and the same formulaic expression: Homeric kléwos áphthiton and Vedic śravas akṣitam meaning 'imperishable glory', designating the supreme recompense of the warrior.

**Historical Discovery:**
The mid-19th century saw Adalbert Kuhn in 1853 equating Homeric Greek and Rigvedic sravas aksitam, both meaning 'imperishable, unfailing fame', with his innovation being the equation of two phrases in two languages rather than just individual words.

**Calvert Watkins and PIE Poetics:**
The expression kleos aphthiton is discussed in Calvert Watkins' "How to kill a Dragon, Aspects of Indo-European Poetics", which appears to be the work referenced in your query.

**Linguistic Evidence:**
This represents one of the rare pieces of evidence from which we can infer the existence of stock poetic expressions from the time of common Indo-European onwards.

**Proto-Indo-European Origin:**
Scholars have long proposed that these expressions share a common origin in the Proto-Indo-European form klewos n̥dhgwhitom.

I've found relevant search results on this academic debate. Here's what the sources reveal:

## The Core Debate

Sanskrit's Rigveda contains retroflex consonants (ṭ/ḍ, ṇ) with about 88 words in the Ṛg Veda having unconditioned retroflexes, which is cited as evidence of substrate influence from contact with a foreign language family rich in retroflex consonants.

## Positions on Dravidian Substrate

**Witzel's Position:** Witzel initially used the term "Para-Munda" to denote a hypothetical language related to modern Munda languages, which he identified as "Harappan," the language of the Indus Valley civilization. He argues that the Rigveda shows signs of this hypothetical Harappan influence in the earliest level and Dravidian only in later levels, suggesting Indo-Aryans encountered speakers of Dravidian not before middle Rigvedic times.

**Krishnamurti's Position:** Krishnamurti argues the Dravidian case for other features, noting the Ṛg Veda has used the gerund with the same grammatical function as in Dravidian, and also attests the use of iti as a quotative clause complementizer. However, such features are also found in the indigenous Burushaski language of the Pamirs and cannot be attributed only to Dravidian influence on the early Rigveda.

**Hock's Position:** Hock argues that Dravidian should not be considered as significant, but that retroflexion is, rather, the outcome of areal features cutting across language boundaries in the Northwest of the Indian subcontinent.

Based on the search results, here's what I found about Brugmann's law and its relationship to Proto-Indo-Iranian *o lengthening in open syllables and Sanskrit:

## Overview

Brugmann's law, named for Karl Brugmann, is a controversial sound law stating that in the Indo-Iranian languages, an earlier Proto-Indo-European *o became *a in Proto-Indo-Iranian, but became *ā in open syllables when it was followed by a single consonant and another vowel.

## The Mechanism

In open, non-final syllables, the vowel *o is lengthened and becomes *ā. In all other contexts, *o becomes short *a.

## Examples in Sanskrit

For example, the Proto-Indo-European noun for 'wood' was *dóru, which in Vedic became dāru. Another classic example is Sanskrit pitaraḥ, mātaraḥ, bhrātaraḥ for "fathers, mothers, brothers" but svasāraḥ for "sisters".

## Ongoing Debate

Kiparsky (2010) has argued for a revised version of BL in which the accent and ablaut properties of the affected forms play a role, hence essentially for a synchronic morphophonological rule. This shows that while Brugmann's law is widely accepted, there remains scholarly discussion about its precise formulation and mechanisms.

Regarding the specific word meaning "eight": aṣṭan is composed of aś + tan (cf. aśīti), and means eight. The plural forms are aṣṭa or aṣṭau.

Once ṣ was established, it "infected" adjacent dental consonants (like t or n), turning them into retroflexes (ṭ or ṇ) through assimilation. Example: iṣ-ta (wanted) became iṣṭa.

Regarding the Proto-Indo-European origin (h₃ekteh₃), Pāṇini's rule is now known to reflect a change of at least Proto-Indo-Iranian date since Old Iranian has precisely the same distribution of h (< PIIr. *s) and š (< PIIr. *š) as Sanskrit.

The search results discuss how these retroflex changes represent regular sound changes inherited from Proto-Indo-European phonology rather than solely being borrowed from Dravidian languages.

Based on the search results, here's what I found about the RUKI sound law:

## Overview

The ruki sound law is a historical sound change that took place in the satem branches of the Indo-European language family, namely in Balto-Slavic, Armenian, and Indo-Iranian.

## The Sound Change

According to this sound law, an original *s changed to *š (a sound similar to English ⟨sh⟩) after the consonants *r, *k, *g, *gʰ and the semi-vowels *w (*u̯) and *y (*i̯), as well as the syllabic allophones *r̥, *i, and *u.

## Retroflexion

In the second stage, leveling of the sibilant system resulted in retroflexion (cf. Sanskrit ष [ʂ] and Proto-Slavic), and later retraction to velar *x in Slavic and some Middle Indic languages.

## Historical Development

This rule was first formulated by Holger Pedersen, and it is sometimes known as Pedersen's law. The rule was originally formulated for Sanskrit. It was later proposed to be valid in some degree for all satem languages, and exceptionless for the Indo-Iranian languages.

The name "RUKI" comes from the triggering sounds (r, u, k, i) that caused the phonetic change in this sound law.

I've found comprehensive information about echo reduplication, m-words, and their areal distribution. Here are the key findings:

## Echo Reduplication in South Asia

Echo words are a form of reduplication that functions as a widespread areal feature in the languages of South Asia. Echo words are characterized by reduplication of a complete word or phrase, with the initial segment or syllable of the reduplicant being overwritten by a fixed segment or syllable.

In most languages in which this phenomenon is present, echo words serve to express a meaning of "... and such; and things like that."

## M-Reduplication

M-reduplication can be exemplified by the Turkish construction kitap-mitap, and this phenomenon is found in languages as distant as Khalkha Mongolian, Bulgarian and Dargwa. This represents a significant areal feature that extends beyond South Asia.

## Turkish and Armenian

In Turkish, one reduplication strategy involves taking the first syllable of the adjective, dropping the syllable-final phoneme, and adding one of four interpolated consonants (p, s, m, r). In Armenian, reduplication follows the same classification as in Turkish, including echo reduplication, as in սեղան-մեղան (table schmable).

## Indian Languages

Echo formation, a kind of partial reduplication, is often considered a characteristic of languages in the Indian Sprachbund.

Based on the search results, I can provide you with information about Burrow and Emeneau's foundational work on Dravidian-Sanskrit linguistic connections, though the specific Tamil words you mentioned (kuṭi, mīna, daṇḍa, nīra) don't appear in these particular results.

The most significant and monumental work of the 20th century was A Dravidian Etymological Dictionary (DED, 1961; revised 1984) by British linguist Thomas Burrow and Canadian linguist Murray B. Emeneau. Much that has been accomplished in comparative phonology and reconstruction is indebted to this work.

Many scholars have suggested that there is in fact a Dravidian substratum in Sanskrit. There are an estimated thirty to forty Dravidian loanwords in Vedic.

The work by Burrow and Emeneau has been central to understanding linguistic substrate relationships between Sanskrit and Dravidian languages, particularly Tamil. However, for detailed analysis of the specific etymological entries and phonological correspondences for the particular words you mentioned (kuṭi, mīna, daṇḍa, nīra), you would need to consult the Dravidian Etymological Dictionary directly or specialized studies examining those particular lexical items.

Based on the search results, here's information about Grimm's Law and the nine consonants involved in the Germanic sound shift:

## Overview

Grimm's law, also known as the First Germanic Consonant Shift or First Germanic Sound Shift, is a set of sound laws describing the Proto-Indo-European (PIE) stop consonants as they developed in Proto-Germanic in the first millennium BC, first discovered by Rasmus Rask but systematically put forward by Jacob Grimm. In 1822, Jacob Grimm put forth the rule in his book Deutsche Grammatik and extended it to include standard German.

## The Nine Consonants

Grimm described two consonant shifts involving essentially nine consonants. Grimm's Law affected the Indo-European stop consonants, or stops, which could be articulated as labial, dental, or velar sounds.

## The Three Phases of Sound Shift

Grimm's law consists of three parts, forming consecutive phases in the sense of a chain shift. Proto-Indo-European voiceless stops change into Proto-Germanic voiceless fricatives. Proto-Indo-European voiced stops become Proto-Germanic voiceless stops. Proto-Indo-European voiced aspirated stops become Proto-Germanic voiced stops or fricatives (as allophones).

## Examples

According to the law, the ancient unvoiced p, t, k became the English unvoiced f, th, h and the Old High German f, d, h, producing such correlations as that between the initial consonants of Greek pod-, English fod, and Old High German fuo. The law further stated that the ancient voiced b, d, g became the English unvoiced p, t, k and the Old High German spirant stops f, ts, kh—hence the correlation between Latin duo, English "two," and modern German zwei (pronounced "tsvai").

Based on the search results, I found relevant information about the relationship between Sanskrit *iti* and Dravidian quotative complementizers. Here's what the research shows:

The quotative marker *iti* represents extensive grammatical influence on Vedic Sanskrit, a grammatical feature not found even in Avestan, a sister language of Vedic Sanskrit. Rigvedic language attests the use of *iti* as a quotative clause complementizer.

The connection to Dravidian languages is significant: The Dravidian and Munda language families feature a word used like *iti*, suggesting that this use of *iti* was likely borrowed from those languages. The use of the Sanskrit quotative marker *iti* is among the most important structural features that spread from Dravidian to Indo-Aryan.

However, there is scholarly debate about the mechanism of influence. One perspective suggests the quotative had developed independently in both language sets as a result of typological pressure from the 'strict SOV restriction' that permits them to accommodate subordinate structures. Others argue these features indicate substratum influence rather than simple borrowing.

The search results did not specifically mention the Dravidian forms *enru* or *ennu*, though they confirm the broader pattern of quotative complementizer influence and convergence between Sanskrit and Dravidian languages.

Based on the search results, here's what I found about the centum-satem isogloss and its status as an areal innovation rather than a primary split:

## The Centum-Satem Division: An Areal Feature, Not a Primary Split

The centum-satem distinction does not imply a strict binary family tree split and is considered an areal feature rather than a primary genetic divide. Since the early 20th century at least, the centum–satem isogloss has been considered an early areal phenomenon rather than a true phylogenetic division of daughter languages.

The shift in understanding came with new linguistic discoveries. The understanding of the centum-satem division began to shift in the early 20th century with the decipherment of Hittite and Tocharian, which unearthed complexities that challenged the notion of a strict evolutionary split between the two branches. The proposed phylogenetic division of Indo-European into satem and centum "sub-families" was further weakened by the identification of other Indo-European isoglosses running across the centum–satem boundary, some of which seemed of equal or greater importance in the development of daughter languages.

The key phonological distinction involves different treatment of the Proto-Indo-European dorsal consonants: In centum languages, palatovelars merged with the plain velars, preserving velar articulations, as illustrated by the Latin word centum ("hundred"). Conversely, satem languages feature a fronting or palatalization of the palatovelars, resulting in sibilants such as *s, *ś, *š, or affricates, evident in Sanskrit śatám ("hundred").

Based on the search results, here's comprehensive information about Verner's law:

## Overview

Verner's law, stated by Karl Verner in 1875, describes a historical sound change in the Proto-Germanic language whereby voiceless fricatives *f, *þ, *s and *x, when immediately following an unstressed syllable in the same word, underwent voicing and became respectively *b, *d, *z and *g.

## The Problem It Solved

Verner's law marked a pivotal advancement in historical linguistics by resolving apparent exceptions to Grimm's law, thereby bolstering the Neogrammarian principle that sound changes operate without exception when properly conditioned. There appeared to be a large set of words in which the agreement of Latin, Greek, Sanskrit, Baltic, Slavic etc. guaranteed PIE *p, *t or *k, and yet the Germanic reflex was a voiced consonant (*b, *d or *g).

## Verner's Discovery

The apparently unexpected voicing of voiceless fricatives (and their falling together with *b, *d, *g) occurred if they were non-initial and immediately preceded by a syllable that carried no stress in PIE. The original location of stress was often retained in Greek and early Sanskrit, though in Germanic stress eventually became fixed on the initial (root) syllable of all words.

## Publication

This law was first presented in an article, "Eine Ausnahme der ersten Lautverschiebung" ("An Exception to the First Sound Shift"), in the Zeitschrift für vergleichende Sprachforschung in 1876, by the Danish linguist Karl Verner.

The search results provide information about the Iranian s to h sound shift. Here are the key findings:

## The S to H Sound Change in Iranian

In Iranian languages, h replaces s except before nonnasal stops and after i, u, r, vocalic r, and k—with examples like Avestan hapta- 'seven' and Old Persian haruva- 'whole' corresponding to Sanskrit sapta- and sarva-.

## Examples with "Hapta" and "Hindu/Sindhu"

In Avestan, 'Sapta Sindhu' was referred to as 'Hapta Sindhu' with Sindhu pronounced as 'Hindu', because the Iranians replaced 'Sa' with 'Ha'. This sound change is part of the broader phonological transformation of the Iranian languages compared to their Indo-Aryan relatives.

The examples you mentioned—hapta (seven), haoma, and the transformation of Sindhu to Hindu—are classic illustrations of this regular sound correspondence between Sanskrit (which preserves the original *s) and Avestan/Old Persian (which shows h in these positions).

I've found comprehensive information about the semantic reversal of deva/daeva and asura/ahura in Indo-Iranian religions. Here are the key findings:

## The Semantic Inversion

The term daeva is cognate with the Sanskrit deva (meaning benevolent deity), reflecting an inversion in Zoroastrian theology where pre-Zoroastrian Indo-Iranian gods were recast as demonic forces by the prophet Zarathushtra to emphasize monotheistic devotion to Ahura Mazda.

In Vedic tradition, Devas are the gods, associated with light, order, and cosmic balance. In Zoroastrian texts, however, the word Daeva refers to false gods or deceptive forces that lead people away from truth.

## Parallel Inversion: Asura/Ahura

A complementary reversal occurred with the asura/ahura terms. In Zoroastrianism, the reformer Zarathustra declared that Ahuras were to be venerated as divine, while Daevas (cognate with Devas) were false gods to be rejected.

## Scholarly Debate

However, scholars debate the origins of this reversal. The daemonization of the asuras in India and the daemonization of the daevas in Iran both took place "so late that the associated terms cannot be considered a feature of Indo-Iranian religious dialectology". In the Gathas, the oldest texts of Zoroastrianism and credited to Zoroaster himself, the daevas are not yet the demons that they would become in later Zoroastrianism.

The evidence suggests these were independent theological developments in the two branches of Indo-Iranian civilization rather than features of a shared proto-Indo-Iranian religious system.

Here are the search results for your query about Jakobson's work on "mama" and "papa" nursery words and universal kinship terms from 1959:

## Overview

Roman Jakobson wrote "Why 'mama' and 'papa'?" in 1959 in response to anthropologist George Murdock's request for an explanation of data Murdock had compiled of "nursery forms" in various countries.

## Jakobson's Theory

Murdock discovered that 52% of sampled societies used some syllabic combination of [ma, me, no, na, ne, no] to denote 'mother,' while 55% used some combination of [pa, po, ta, to] to denote 'father.'

Jakobson reasoned that all an infant had to do was open his mouth and vibrate his vocal folds to produce the vowel [a], and by smacking his lips together, the infant could easily produce the bilabial consonants [m, b, p].

These nursery forms, Jakobson wrote, "are based on the polarity between the optimal consonant and the optimal vowel".

## Connection to Adult Kinship Terms

According to Jakobson, mama/papa words gave rise to our adult parental words mother and father: in Indo-European, the intellectualized parental designations mātēr and pətēr were built from the nursery forms with the help of the suffix –ter.

## Key Insight

'Mama' and 'papa' weren't passed down through the ages; rather, they were reinvented by each infant, as she began to explore the phonetic abilities available to her.

Based on the search results, here's what I found regarding Sanskrit aśva, Avestan aspa, and the Indo-Iranian sound changes:

The Sanskrit term aśva (अश्व), denoting "horse," derives from the Proto-Indo-Iranian HáćwaH, which in turn stems from the Proto-Indo-European reconstructed root h₁éḱwos, signifying "horse" or a swift equine animal.

This root underwent phonetic shifts in the Indo-Iranian branch, where the initial laryngeal h₁ was lost, the vowel é simplified to a, and the velar ḱw evolved into śv through palatalization and labial retention, yielding the Vedic nominative form aśvaḥ.

Cognates of aśva illustrate the root's wide distribution: in Iranian languages, Avestan aspa preserves a near-identical form, reflecting shared Indo-Iranian heritage.

The search results also show how different Iranian languages handled the *ḱw sound differently: In Avestan and the great majority of Iranian languages, *ḱw and *ǵ(h)w become sp (as in Av. aspa-), while the languages of the nomadic Saka peoples show a different development of *ḱw to š (as in Khot. aśś [aša–] "horse").

Based on the search results, here's what I found about PIE word order, SOV reconstruction, and the scholars you mentioned:

## Key Scholars and Their Positions

Winfred P. Lehmann's influential 1974 work *Proto-Indo-European Syntax* consistently referred to the proto-language as SOV or OV, with OV describing word order across the board. Paul Friedrich (1975) disagreed with Lehmann's analysis, and Friedrich noted that even among Indo-European languages with basic OV word order, none are rigidly OV, and he argued for a VO common ancestor.

## Typological Validation and Hock's Work

Hans Henrich Hock's 2013 article focuses on the position of the finite verb in Proto-Indo-European, and points out that recent typological research does not exclude the occurrence of relative clauses containing relative pronouns and finite verbs in SOV languages. Such structures are therefore reconstructable for a proto-stage with an SOV order, despite earlier arguments against such a reconstruction by Lehmann and Friedrich.

## Current Scholarly Consensus

Hans Henrich Hock (2015) reports that while the SVO hypothesis still has some adherents, the "broad consensus" among PIE scholars is that PIE would have been an SOV language.

Here are the search results for your query about Sanskrit to Prakrit sound changes, including information about MIA (Middle Indo-Aryan), gemination, intervocalic lenition, and references to Pischel and Bloch:

## Key Sound Changes from Sanskrit to Prakrit

**Intervocalic Lenition:** All single intervocalic unvoiced stops become voiced, then non-retroflex stops spirantize (for example g, d, b > ɣ, ð, β / V_V). Finally, aspirated spirants debuccalize, the spirant β > ʋ, and remaining spirants ɣ, ʑ, ð are lost, leaving the surrounding two vowels in hiatus.

**Gemination:** Complex consonant clusters are assimilated into geminate consonants or split through epenthetic vowel, e.g. Skt. sarpa 'snake' vs MIA sappa; Skt. ratna 'jewel' vs MIA ratana.

**Retroflex Stops:** The retroflex stops ɖ/ɖʰ often become ɭ/ɭʰ in intervocalic position (allophones).

## Scholarly References

Studies in the grammar of Prakrit languages are 170 years old in Europe, starting with Lassen (1837) and continuing with Pischel (1900) or Nitti-Dolci (1938). The search results reference Pischel's work on Prakrit comparative grammar and Bloch's contributions to the field.

Based on the search results, here's what I found about the South Asian Sprachbund and Emeneau's work on areal features:

## South Asian Sprachbund Overview

In a classic 1956 paper titled "India as a Linguistic Area", Murray Emeneau laid the groundwork for the concept of a sprachbund by observing that the subcontinent's Dravidian and Indo-Aryan languages shared areal features that were not inherited from a common source, but resulted from diffusion during sustained contact.

## Key Areal Features

The areal features identified by Emeneau include retroflex consonants, echo words, subject–object–verb word order, discourse markers, and the quotative. Only retroflex consonants and dative subjects are exclusively South Asian.

## Language Families Involved

Emeneau specified that language and culture had fused for centuries on the Indian soil to produce structural convergence of four distinct language families: Indo-Aryan, Dravidian, Munda and Tibeto-Burman.

The search results I found discuss the quotative and dative features you mentioned, but do not provide specific detailed information about the conjunctive participle and other specific grammatical features you asked about in relation to these areal features.

Based on the search results, here's what I found about the Tamil minimal pair with "paṭu," "patu," and "pattu":

The minimal pair distinction in Tamil includes பத்து (pattu, ten) vs. பட்டு (paṭṭu, silk). This exemplifies the contrast between dental consonants – where your tongue touches your upper teeth – and retroflex consonants, where your tongue curls back to touch the roof of your mouth further back.

The search results also provide additional examples of this same type of phonological contrast: நாது (nātu, we planted) vs. நாடு (nāṭu, country) and கத்து (kattu, shout) vs. கட்டு (kaṭṭu, bundle).

To clarify, the specific words you asked about are:
- **pattu** (with dental -tt-) = "ten"
- **paṭṭu** (with retroflex -ṭṭ-) = "silk"

These represent a fundamental distinction in Tamil phonology where Tamil phonology is characterised by a lack of aspirated sounds, presence of retroflex consonants, and multiple rhotics and nasals. The dental-retroflex contrast is particularly important for Tamil speakers and challenging for English speakers, since this contrast doesn't exist in English.

Based on the search results, I can provide you with relevant information about conjunctive participles as a South Asian areal feature:

Conjunctive participles (also referred to as general converbs in South Asian linguistics) are features whose presence is pan-Indic. These non-finite verbal forms express an action that occurred before another one expressed by the main verb and exist in Indo-Aryan, Dravidian, Munda and Tibeto-Burman.

Emeneau (1956) identified the existence of an Indian linguistic area and called attention to the spread of features throughout the subcontinent, including the pan-Indic presence of general converbs (commonly called "conjunctive participles" in South Asian linguistics).

The search results confirm that conjunctive participles/converbs are indeed a recognized South Asian areal feature shared across Indo-Aryan and Dravidian language families, though the specific morphological forms you mentioned (-tvā and -ya) are not elaborated upon in these particular results.
