October 8, 2019: a paper on the origins of Kra-Dai tones is now published (here). It represents my current understanding of the formation of Kra-Dai tones and supersedes the present three posts. There are more data in the paper, especially on the Austronesian final consonant I note as *X; there are also some significant differences between the present posts and the paper. Thus, although it is clear that the word ‘excrement’, ususally reconstructed as *Caqi, ended in some kind of guttural fricative, it contains too many irregularities, possibly euphemistically motivated (as noted by Wolff), both in Austronesian and Kra-Dai, to identify that fricative. Therefore in the published paper I retreat from my suggestion that *Caqi ‘excrement’ was really *Caqix. I suggest instead that final *-x was the value of Tsuchida’s *-H2, thus converging with Blust’s proposal, but on completely different grounds (pages 7-9).
Like Old Vietnamese, Written Burmese and Proto-Hmong-Mien, the Kra-Dai languages exhibit a phonological typology strongly influenced by a form of Chinese which is later than Old Chinese and earlier than Early Middle Chinese: that is, a period extending beginning c. 200 BCE and covering the first half of the first millennium CE. Their tone system is structurally identical to that of Chinese of that time: three contrasting tones on words ending in sonorants (vowels, semi-vowels, nasals, liquids) while words ending in oral stops do not show any tonal contrast. The origin of the Vietnamese tone system was elucidated by Haudricourt (1954a): one tone originated in words ending in [h], another in [ʔ], a third in sonorants. Haudricourt (1954b) showed that the Chinese qùshēng 去聲 originated in an *-s suffix which evolved to [h] prior to becoming a tone. Mei (1970) completed Haudricourt’s picture by proposing that the Chinese shǎngshēng 上聲 goes back to words ending in a glottal stop. For details see Sagart (1999). The origins of the Burmese, Hmong-Mien and Kra-Dai tones have not been elucidated although some progress has been made for Kra-Dai by Ostapirat (2005) and Norquest (2013). Here I describe additional hypotheses which bring us closer to a solution.
The Kra-Dai tones are known as A, B, C and D. The core of these categories existed in Proto-Kra-Dai (Ostapirat 2000), though not necessarily as true phonetic tones having pitch as their main acoustic clue. When borrowed into Kra-Dai, Middle Chinese píngshēng 平聲 words (ending in sonorants in Old Chinese) typically have tone A; Middle Chinese shǎngshēng 上聲 words (ending in a glottal stop in Old Chinese) are treated by tone C; MC qùshēng 去聲 words (ending in *-h in late OC < OC *-s) show tone B. Chinese words ending in oral stops form the so-called rùshēng入聲 category. They do not contrast with the other Chinese tones. Kra-Dai ‘tone’ D is the corresponding category in Kra-Dai. Gedney (1978) suggests that the phonetic values of the Thai tones A, B and C are the same as the Old Chinese values of the Chinese píngshēng, qùshēng and shǎngshēng respectively, under the Haudricourt-Mei solution: sonorant endings, [h]-endings, [ʔ]-endings. Earlier attempts to solve the origin of Kra-Dai tones have assumed Gedney’s hypothesis.
Sagart (2004, 2005, 2008, 2011) argued that the Kra-Dai languages are a subgroup, not a sister, of the Austronesian language family. Here I attempt an account of the Kra-Dai tone categories from the viewpoint of Austronesian consonant endings. It should be borne in mind that the AN words in Kra-Dai, while very basic, are quantitatively limited: for that reason my proposals are based on small numbers of examples. This post deals with the Kra-Dai tone C. Two other posts deal with tones B (here) and A (here).
In examining the Kra-Dai tone categories in connexion with Austronesian, reference must be made to Tsuchida’s reconstruction of two final consonants (Tsuchida 1976): *H1 (-h in Pazeh, Saisiyat, Atayal, Sediq, Amis and Aklanon) and *H2 (-h in Takituduh and Aklanon). AN words ending in *H1 form the core of the Kra-Dai tone C:
|PAN(Sa)||Buyang (Li 1999)||PHlai(Os)||PTai(Pi)|
|‘to come, go’||*uwaH1||va11 < C2||—||—|
|‘head’||*quluH1||qa0 ðu11 < C2||*uRəu C||*kraw C|
|‘shoot, outgrowth, flower’||*buŋaH1||ma0 ŋa11 < C2||—||—|
PAN(Sa): Proto-Austronesian (Sagart, this post); PHlai(O): Proto-Hlai (Ostapirat 2004); PTai(Pi): Proto-Tai (Pittayaporn 2009)
Supporting evidence for these reconstructions:
*uwaH1 ‘to come, to go’: Atayal uah ‘come’, Mantauran Rukai oa ‘go’, Babuza m-oa ‘come’, Puyuma ua ‘go’;
*quluH1 ‘head’ : Paiwan qulu, Sediq (Taroko) qolox ‘skull’, Saisiyat ta-ʔœlœh, Aklanon úeo(h);
*buŋaH1 ‘shoot, outgrowth, flower’: Saisiyat poŋaeh ‘flower’ (p- unexplained; expect b-), Saaroa vuŋavuŋa ‘ear of foxtail’ (own fieldwork, 2014), Kanakanabu buŋabuŋa ‘flower’, Aklanon búːŋah ‘fruit’.
Some Kra-Dai C-category words cannot come from *H1. The word for ‘excrement’, Proto-Kra *kai C, Proto-Hlai *akaːi C, Proto-Tai *C̬.qɯj C, in all likelihood corresponds to a PAN word reconstructed as *C1aq3i (Tsuchida), Blust *Caqi (Blust), *taqí (Wolff). Under the generally accepted sound correspondences, these should yield sai in Pazeh and Kaxabu, two closely related languages of central-western Taiwan. If the word had ended in *-H1, saih would be expected in both. The attested forms are Pazeh saik, Kaxabu saix (Tun 2015). Recently, thanks to my friends Prof. Hsing Yue-ie and Hsu Tze-fu of the Institute of Microbial and Plant Biology, Academia Sinica, I was able to visit Mr Tun in Puli and to record his pronunciation of this word (here). Blust treats Pazeh saik as a metathesis, but that explanation cannot work for Kaxabu. Currently I do not know any other examples of the correspondence Pazeh –k to Kaxabu –x. One possibility is that the word ended in a rare consonantal ending PAN *-x, preserved unchanged in Kaxabu, and merged with *-k in Pazeh. The aberrant –l ending in Kavalan tal ‘excrement’ would be its indirect reflection, as would tone C in Kra-Dai. This is speculative, as no other example of the final-consonant correspondence shown by ‘excrement’ in Austronesian is currently known.
In two other posts I examine the origins of the Kra-Dai tone B (here). and A (here), B and C. A list of references is appended to the post on tone A.

Pulleyblank proposed a glottal stop as the source of 上聲 on p. 225 of part II of “The consonantal system of Old Chinese” in 1962, eight years before Mei’s article.
Indeed he did. In fact the idea was already in germ in Haudricourt’s 1954 paper on Vietnamese. But it was Mei who in my opinion made a strong case of it, citing (as I recall) evidence from modern dialects preserving a glottal stop in the Shangsheng, from Indic transcriptions and from late Tang perceptual descriptions of contemporary Chinese tone systems by Japanese monks.
