enoughpronoun
as much as neededas much or as many as is needed
Enough stands alone, without a following noun, often before of: I've had enough, enough of this. Directly before a noun, enough is a determiner, a separate entry.
Usage
Enough used alone or with of is a pronoun; directly before a noun, with no of, it is a determiner (enough time). After an adjective or adverb (good enough), enough is an adverb. All three are separate entries.
