Manually Coded Malay

Kod Tangan Bahasa Malaysia (KTBM), or Manually Coded Malay, is the only form of sign language recognised by the government in Malaysia as the language of communication for the Deaf. It is not itself a language, but a manually coded language, a signed form of oral Malay. It is adapted from American Sign Language (or perhaps Manually Coded English), with the addition of some local signs, and grammatical signs representing affixation of nouns and verbs as used in Malay. It is used in Deaf schools for the purpose of teaching the Malay language.
