==Thai year vocabulary==
Thai orthography spells most native words phonetically, though there is no definitive system for
[[Royal Thai General System of Transcription|transcription]] into Roman letters. Here, native Thai words are immediately followed by a vocabulary entry in this pattern:
:''Phonetic'' Thai (Thai phonetic respelling, if different) [Comment] definition; variant definitions.
Example:
:''Thai''  ไทย (ไท)  [Archaic] free, frank; Thai race, language, [[Thai alphabet|alphabet]]; [[thaification|citizen of Thailand]].
