Mày is a Vietic language spoken by the May people of Minh Hóa district, Quảng Bình province, Central Vietnam.
It is a member of the Cheut language cluster, which belongs to the Vietic branch of the Austroasiatic family.
[3] May is spoken in the villages of Ca Oóc, Bai Dinh, and Cha Lo.
Unique phonological characteristics in May include the coda -ɽ, derived from proto-Vietic *-s, which stands behind a consonant nucleus, in contrast to final -l/-h/-i̯ found in most other Vietic languages.
The use of clitics and affixes is generally limited and does not undermine the analytical grammar structure.
