For more than 15 years, I have collected some frequent questions on the Thai language from my students. I have tried to group them up and wrote down the questions. In "A Handbook of Thai Language" readers find the following topics: the script system, word classes, classifiers, pronouns, the uses of nouns and verbs, noun and verb phrases’ structures, word structures, pre verbs, post verbs, pre verbs and post verbs in actions, preposition, conjunctions, sentence types and particles. Moreover, do not be surprised when you feel like in my different classes of Thai.
