Kedah Malay
Kedah Malay or Kedahan (Malay: bahasa Melayu Kedah; also known as Pelat Utara or Loghat Utara 'Northern Dialect') or as it is known in Thailand, Syburi Malay (Thai: ภาษามลายูไทรบุรี Phasa Malāyū Saiburī) is a Malayic language mainly spoken in the northwestern Malaysian states of Perlis, Kedah, Penang, and northern Perak and in the southern Thai provinces of Trang and Satun.
The usage of Kedah Malay was historically prevalent in southwestern Thailand before being superseded by the Thai language.
Enclaves of Kedah Malay can be found in Kawthaung District in Myanmar; Ranong and Krabi in upper southern Thailand; Jaring Halus, Langkat and Aceh in Sumatra, Indonesia and up north in Bangkok, central Thailand, where most of the Kedah Malay speakers are descendants of historical settlers from Kedah.
[3] Speakers in Trang as well as Satun are heavily influenced by the Thai language.
[9][10] Note(s): Kedah Malay has four diphthongs /ai, au, oi, ui/ with /ui/ being a surplus diphthong that does not exist in Standard Malay.
