The *i vs. *ə alternation in the Sino-Tibetan word for ‘10’

Some generalizations for a start. Those Sino-Tibetan (ST) words for ‘10’ that end in a labial consonant have the widest distribution and almost certainly reflect the main PST etymon for ‘ten’. They come in two flavors: with vowels *i and *ə. The i-set is limited to Tibeto-Burman (TB). Its members either end in a stop: -ip, -ep, -iap: WB kyip, Limbu gip, Mikir kep, Geman Deng kiɑp/kyep, etc. or—if the stop has been lost— in the vowel preceding it: for instance in some rGyalrongic languages: Japhug sqi, Ergong (Daofu); (Huang and Dai 1992) zʁa ‘ten’, sqha (‘ten’ in ‘20’, ‘30’ etc., from earlier zʁe, sqhe, or zʁia, sqhia). The STEDT website reconstructs *gip ‘ten’, which is fine except that Japhug sqi and Ergong zʁa indicate a uvular initial. Under Matisoff, the STEDT ignores the ST distinction between velars and uvulars. WB kyip, on the other hand, seems to argue against a uvular, since PST uvulars normally go to zero/ʔ (depending on the transcription being used) in Burmese (Peiros and Starostin 1995). Here we probably see the original uvular anteriorized to a velar by the preceding s- in rGyalrongic, a closely related group according to Sagart et al. (2019). This points to a PTB *sɢip.

The STEDT does not give a reconstruction for the ə-vowel set. TB merges *ə into *a, thus the TB forms in this set usually have a low vowel. They include Proto-Tani *čam ‘tens’ (Sun 1993) as in Adi Bokar ʧam– ’10’ in numbers ‘20’ and above. The situation in rGyalrongic is more complex. As already mentioned, Japhug has sqi for ‘10’. In Jacques’s synchronic analysis (2021:236), ‘10’ as a formative in teens is is /sqa/ . Specifically in 11, 12, 13 and 16 it is immediately followed by a labial consonant before the unit number: 11 sqa-p-tɯɣ, 12 sqa-m-nɯz, 13 sqa-f-sum, 16 sqa-p-rɤɣ. The labial element is not inserted in 14 and 15, as the unit number already begins in a labial: sqa-βde, sqa-mŋu. No labial element is inserted in 17-19: sqa-ɕnɯz, sqa-rcat, sqa-nŋɯt. It is of course the lack of an inserted labial in 17-19 which motivates treating -p-, -m-, -f- as insertions: historically they are vestiges of an earlier *-p coda on ‘10’ (pre-Japhug *sqap) assimilated on the following numeral’s initial. Ergong (Huang and Dai 1992) is parallel to Japhug: along with zʁa and sqha, already mentioned for ‘ten’ and its exact multiples, one has ʁɑ in teens (notice the back vowel). The -m endings in Proto-Tani *čam ’tens’ probably also had their *-p ending assimilated on a following nasal: for an unknown reason the *-am forms displaced the *-ap forms. If we wanted to include Proto-Kuki-Chin *soom ‘ten’ (VanBik 2009) in the ə-vowel set, we would need a change ɢ > w, so that *sɢaap/m > swaam > soom. I am not aware of any evidence for that change (noyt that I would necessarily), so the reason for the vowel change may well lie elsewhere.

rGyalrongic holds clues to a solution to the two-flavor problem. Japhug and Daofu have a front vowel when ‘ten’ occurs at the end of a numeral expression—i.e. in ‘10’ and its multiples—vs. a low or back vowel when ‘10’ is non-final, being followed by a unit numeral—in teens. If PST numeral expressions were stressed on the last morpheme and non-final morphemes were unstressed, non-final ‘ten’ would have a more central vowel than word-final ‘10’ phonetically. This could eventually phonologize so that one would get a phonemic contrast between /sɢip/ and /sɢəp/. Only the latter’s ending would have the opportunity to assimilate on a following numeral’s onset—the former was never followed by a numeral. This will explain why the *p ending in the *i-set either remains or falls, but never assimilates, and why only the *ə-set can end in -m.

Tani has lost the i-vowel variant to an innovated form Proto-Tani *rjɯŋ ‘ten’. In all other contexts the ə-variant *čam ‘tens’ has prevailed, even in exact multiples of ten because the Tani order for these numerals is 10-multiplicator, e.g. Adi-Bokar tʃɑmɲi 10-2 ‘twenty’, tʃɑmum 10-3 ‘thirty’, tʃɑmpi 10-3 ‘forty’, tʃɑmŋo 10-5 ‘fifty’. Here we understand why.

Let us now turn to Chinese. The Baxter-Sagart OC reconstruction is *t.[g]əp > MC dzyip ‘10’. This is self-evidently part of the ə-vowel set.  *[g] is shorthand for ‘either *g or *ɢ’. Although after non-pharyngealized onsets OC *-ip and *-əp are indistinguishable—both MC -ip—we are confident that in Old Chinese ‘10’ had OC *-əp because c. 1300-1200 BCE the Oracle Bone inscription graphs for shí 十 ‘10’ and for zhēn //針 ‘needle’ are identical: a vertical stroke. In some bronze inscriptions one end of the stroke is blunt and the other is sharp: clearly a drawing of a needle. Both the loan to Vietnamese găm ‘bamboo or metal pin’ and the WB cognate word ap ‘needle’ are incompatible with *-ip/im. Baxter and Sagart (2014) reconstructed ‘needle’ 箴鍼針 as *t.[k]əm, where [k] is shorthand for *k and *q. Proto-Tai *qem ‘needle’ (Pittayaporn 2009) is a Chinese loanword whose *q- could reflect OC pharyngealized *kˤ-, but not plain *k-. This disambiguates ‘needle’ to OC *t.qəm. Thus ‘10’ and ‘needle’ were phonetically close: *t.ɢəp vs. *t.qəm. Normally the difference in endings would have stood in the way of equivalence in the script. Either ‘needle’ had a doublet with -p (as in WB ap, WT khab, Japhug taqaβ), or ‘10’ had a doublet *t.ɢəm through assimilation on a numeral beginning in a nasal, as in rGyalrongic.

It is as yet unclear if the TB and Chinese preinitials: *s- vs. *t., are relatable. So for PST I suggest a doublet for ‘10’: expression-final *[t,s]V.ɢip, non-final *[t,s]V.ɢəp. Chinese has generalized the non-final form across the entire paradigm. As we saw, TB maintains the two and the context in which the PST vowel distinction first arose is only displayed by rGyalrongic.

Is 袁 yuán ‘long robe’ a ghost word?a response to Guillaume Jacques

In a comment on a post of Guillaume Jacques’s I cited the word 袁 yuán ‘long robe’ as being cognate with Tibetan གོན་ gon “clothing”. This drew a response from Guillaume, from which I extract these passages:

“l’étymologie avec 袁 est difficilement acceptable philologiquement: la glose que tu cites « long robe » est la traduction de celle du shuowen 长衣貌, mais ce mot supposé est sans attestation textuelle (无书证); les dictionnaires ne citent que les gloses de dictionnaires: http://www.guoxuedashi.com/kangxi/pic.php?f=gxhz&p=2055”

and:

“Je pense que l’on ne peut pas utiliser de mots dont l’existence même n’est pas assurée pour faire du comparatisme (en plus quand bien même il aurait existé, la glose X貌 suggère qu’il devait plutôt s’agir d’un idéophone, pas d’un nom).”

Real words do not always occur in the received literature; for instance the Cantonese and Hakka popular word for “egg” has no early Chinese text occurrences, yet it corresponds well to the word “egg” in other ST languages (Baxter and Sagart 2014:324).

Specifically with regard to 袁:

The same word appears written as 褑 and 褤 in the Ji Yun 集韻 with the spelling 于元切= hjwon,and the gloss 衣也 “clothing”. The Ji Yun here is not citing the Shuo Wen, since the characters and the gloss wording are different.

The Shuo Wen itself which says “袁, 长衣貌也” is not citing an earlier dictionary/word list either, since there is no earlier attestation of the character, and the Shuo Wen is the first Chinese dictionary.

Dialectally the word is attested. Huang Kan 黄侃 in his《蕲春语》wrote that a long robe is called 長褑 in his own dialect, noting that the word must be the same as 褑 in the Ji Yun.

Although there are no early text examples of 袁, the character is attested both paleographically and as the head of a phonetic series. It includes 衣 “clothing” and a hand.

There is, then, no reason to assume that 袁 is not a real word. The comparison to WT gon is not problematic.

Tibetan rtswa ‘grass’

In this paper, Guillaume Jacques proposes that the Old Tibetan semi-vowel –w– as part of a word onset is secondary, and that it has its origin in words ending in -u followed by -ba: he supposes the evolution Cu-ba > Cuwa > Cwa, for instance zwa ‘nettle’ < zu-ba, rwa ‘horn’ < ru-ba, grwa ‘corner’ < gru-ba. Another example is ‘grass’, OT rtswa, which must then come from an earlier rtsu-ba. Tibetan rtswa is compared to Chinese *[tsʰ]ˤuʔ > tshawX > cǎo ‘grass, plants’ by Matisoff (here, p. 177) under a reconstruction PST *r-tswa-n, as part of a list of mostly spurious comparisons. In the case of ‘grass’, Matisoff got lucky, but only Jacques’s proposal makes sense of the phonology of this comparison, since OT -a does not otherwise correspond to OC -u.
