A study of Thai linguistics works in 2005 shows that most are M.A. theses and doctoral dissertations done by Thai students in five universities in Thailand and a few universities in the U.S.. and the U.K.. Only three works analyse foreign languages, while the rest investigate the Bangkok Thai dialect. Five main areas are identified: sound and orthography, sociolinguistics, utterance semantics, lexical semantics and syntax-semantic interface. More works focus on the last two areas. With regard to the frameworks used in the analyses, pragmatics, discourse, and speech acts are found most often. Several topics such as village names, politeness, and slang, which have been studied previously, were investigated again in 2005 with different locations or different groups of speakers. Although such investigations may yield additional information on the topics, new questions or new probes into similar data may be preferable.
