In their Notes d'Etymologie Taï, published in 1926 in the Journal of the Siam Society, vol. xx, pt. i, MM. J. Burnay and G. Coedès have compared the various Taï words meaning “a hundred”. Ahom pāk, Shan pāk1, Khamti pāk1, White Taï pdk1, Thô pāk1, Nùng pāh1, Dioi pā1—all go back to a form *pāk, which is very close to the sixth century Chinese (pak).
