enough means 'as much as necessary'. It can be used with an adjective, an adverb, a verb or a noun. It can also act as a pronoun.

We know what the noun is because of the context.
With an adjective and a noun
When enough is used with an adjective and a noun, two positions are possible but the meaning changes.
We haven't got big enough envelopes.
We haven't got enough big envelopes.
When enough is after the adjective (big enough envelopes), it describes the adjective – the envelopes are too small. When enough is before the adjective (enough big envelopes), it describes the noun phrase – we have some big envelopes, but we need more.
We normally only use enough of when it is followed by a determiner or a pronoun (a/an/the, this/that, my/your/his, you/them, etc.).
There isn't enough of that bread to make sandwiches for everyone.
