Sawadeekrup is Thai for "hello". If you want to try greeting someone in English you can say "hello"! I think in Thai there are slight differences in pronunciation in words when a man is speaking compared to a woman. But in English there is no difference. Not sure what the question is asking but I guess you mean something like this?

This is Thai language for "hello", right? I do not understand the question.

Sawadeekub is not an English word, so I don't think English speakers can help you with that one.
