As an adjective, 'enough' describes a sufficient quantity, degree, or extent of a noun.
We have enough food for the party.
There aren't enough chairs in the room.
I hope we've made enough copies for everyone.
When 'enough' is used as an adjective, it's essential to ensure it directly modifies a noun. For instance, 'enough water' or 'enough time.'
as an adverb, 'enough' modifies an adjective, adverb, or verb to indicate the sufficiency of the degree or manner of the action.
She's old enough to make her own decisions.
He doesn't run fast enough to beat the record.
I can't emphasize enough how important this is.
It's crucial to differentiate between the adverbial and adjectival uses of 'enough.' For instance, 'She's strong enough' (adverb modifying an adjective) vs. 'She has enough strength' (adjective modifying a noun).
A common mistake is misplacing 'enough' when it's used as an adverb. For example, 'She's enough strong' is incorrect; it should be 'She's strong enough.'
