entire

Entire means all of it, with nothing left out. She ate an entire pizza. The entire street lost power. He spent the entire afternoon looking for the keys that were in his coat.

It leans a little harder than whole, and it likes to stand in front of the noun: the entire building, my entire family, the entire point. It will not sit after the verb, so a cake is whole, never entire. Entirely is the adverb for completely: entirely my fault, not entirely true. The noun entirety turns up in one phrase worth knowing, in its entirety, meaning all of something taken together, as when a report is published in its entirety rather than in pieces.
