Learn Thai Slang Words & Idioms

Are you a Thai language student looking for the latest Thai idioms and slang? A tourist looking for a Thai language book that’s not filled with the same old stuff? An English teacher struggling to understand your Thai students? An expat professional wanting to communicate with Thailand’s young generation? If the answer is yes, then the Thailand Book of Slang flip book below will help you.

More than just giving you new vocabulary, this book of Thai slang words and idioms provides hundreds of sample sentences to advance your skills in listening, talking, and reading the colloquial language of Thailand. It also will help intermediate Thai language students struggling to master the tricky usage of Thai particles. Lastly, for those foreigners who are studying Thai, but whose native language is not English, you’ll probably pick up a bunch of new English phrases to boot!

This book of Thai slang words is organized to make it easy for you to navigate. The Thai idioms and slang are arranged alphabetically by their transliteration (phonetic spelling). Each entry is followed by an English definition and two English words or phrases that match the Thai. This vocabulary is used in the comic and in the sample sentence below the definition. The Thai translation of the English sample sentence is followed by its transliteration and by a literal word-for-word translation, so that students can better understand the vocabulary used and how the sentence is organized. At the bottom of each page is a transliteration of the Thai slang used in the comic, followed again by its literal translation. Lastly, there is an English word index in the back of the book, which can help you locate matching Thai entries.

Remember that the words and phrases listed in this book are mostly Thai slang words and idioms. While not vulgar, many of the entries are not what many adult Thais would call “polite” speech. The comics and sample sentences are the way teens and young adults talk when among friends. It is not recommended that you use this language when talking to people older than you, or in a professional setting. As a guide, we have rated the Thai vocabulary as (G) for general inoffensive words, (PG) for slightly stronger language, and (R) for words which should not be used except when with close friends. The English words and phrases are likewise rated.
