What is the meaning of does in hindi?

Hindi doesn't really have one word for 'does'. It's more of a grammar thing. For example, to ask "Does he go?", you add the word 'kya' at the start of the sentence. The main verb also changes its ending based on who you are talking about. So the idea of 'does' is built into the other words. It is not a separate word you can just look up. It's a little tricky at first
