what,where ,who,which,who,whom,how都是什么词性

what who which who whom 是代词,在句中可做主语,宾语和表语,但whom中做宾语.如 What is happening in the classroom?I believe what you said.Could you tell me which is the nearest way to the post office?Give...那么why与whether什么词性why是副词,在句中做状语。whether无词性,只有词义引导名词性从句,不做从句成分。如I don't know whether he likes the gift that I gave him.The reason why he didn't go to school is that he was will.
