Today "why" is used as a question word to ask the reason or purpose of something. I don't know why, but it seems to me that bob would sound a bit strange if he said, "why is it that you have to get going?" in that situation. Nov 7, 20138 1) please tell me why is it like that.
Why is it like that? You never know, which is why. Only have similar answers where the reason for something is the cause.
This is the case for a question like "why is the boy so big?" — he has eaten. What part of speech is "why?" i think it modifies the verb "is", so i think it is an adverb.
