Whatever means no matter what, or anything at all. Whatever happens, whatever you like, whatever the cost.
It introduces a clause meaning it makes no difference: whatever he says, I am going. It also means anything of a kind: take whatever you need. On its own, whatever is a dismissive reply meaning I do not care and this conversation is over — which is one of the most efficient and most annoying words in English. Note whatsoever, which is an emphatic form used after a negative: no evidence whatsoever.
