Prai (Phray) or Phai, also known as Thin (Htin), is a MonâÂÂKhmer language of Thailand and Laos. There are several closely related, but not mutually intelligible dialects which go by the names Prai and Thin. They are also closely related to Mal, together forming the MalâÂÂPhrai group of languages, sometimes collectively called Lua' language (because they are spoken by the Lua people).
All vowels can be long or short.
