How to Ask WH Questions in Thai?

Written By: Hugh Leong

It is common for beginning students of Thai (or students of most foreign languages for that matter) to start off making sentences and answering the teacher’s questions. In fact, quite often the art of ASKING questions is frequently left to much later, and sometimes is forgotten altogether. This is a problem with Thai since Thai questions are asked in quite a different way than English questions.

Word Order

Word order of Thai “wh” questions – who, what, where, how, why – is different from the word order of English questions. The question words are in a different place.

In English, the question word begins the sentence, so everyone knows the question is coming. Thai needs to set you up first. If you want to know where something is, you name that thing first and then use the question word. So, “where is the book?” in Thai word order becomes “the book is where?” Exceptions are the why questions where the question word is either in front or behind, such as “why are you sad?” or “you are sad why?”

Note that tenses in Thai questions such as in “what will”, “what did”, “what are”, as well as all the other “wh” type questions use the same pattern. It takes adding other context words to clarify your meaning.

For example with: “what will you do tomorrow“, “what did you do yesterday“, “what are you doing now“, “what are you doing tonight“. And even though there is a nice future indicator in Thai such as จะ /ja/, as well as other time indicators, they are often dropped.

If everyone understands the context, then these words are not needed. But many an Expat is left confused as to whether they are being asked about something they did, or will do, or are doing. When I am the one doing the asking, in order to be understood I use the context words.

There are so many ways to ask questions. I have shown just a few here but you are sure to come across many more question patterns. Observe the word order in the examples below. The Thai question words have been underlined for clarity.
