We have used the Royal Thai General System of Transcription, published by the Royal Institute of Thailand, to romanize Thai expressions, although we have introduced a few minor exceptions for the benefit of readers unfamiliar with Thai pronunciation. Instead of the RTGST vowel ue, we use ?, resulting in m?ang rather than mueang. The RTGST does not distinguish between the aspirated and unaspirated forms of ch, but we render the unaspirated form as j, producing thammajak rather than thammachak. For words and names that have acquired a familiar romanized form, such as baht or Chulalongkorn, we have retained that form rather than applying our version of the RTGST to make them bat and Julalongkon. Similarly, we have not changed the romanization of proper names that individuals have transliterated themselves, nor have we altered the romanization of words and phrases in quoted material.
