How do you say what is your name in thai?

Answer 1

Kuhn cheu a-rai krup/ka (literally - you name what is - followed by polite ending krup or ka)

Kuhn (You, polite formal, spoken like English word spoon but don't hold it too long, middle tone)

Cheu (Name, not a direct equivalent for the "eu" in English but close to the noise you might make when you see something distasteful, best to hear audio, falling tone)

A-rai (Question word, many times the single trilled "r" is replaced with an "L" sound, this is a short "a" as the "u" in the English word "cut" immediately followed by the English word lie)

Covered many times in Answers, the polite word endings for a male speaker is krup (or quickened to kup by many, high tone) and ka for female speaker (falling tone)

Answer 2

You can say "คุณชื่ออะไร" (pronounced as "kun chue arai") in Thai, which means "What is your name?"
