Enough goes after adjectives and adverbs:
– I can’t run very far. I’m not fit enough. (not enough fit)
– Let’s go. We’ve waited long enough.
– Is Joe going to apply for the job? Is he experienced enough?
Compare too … and not … enough:
– You never stop working. You work too hard.
(= more than is necessary)
– You’re lazy. You don’t work hard enough.
(= less than is necessary)
Enough normally goes before nouns:
– I can’t run very far. I don’t have enough energy. (not energy enough)
– Is Joe going to apply for the job? Does he have enough experience?
– We’ve got enough money. We don’t need any more.
– Some of us had to sit on the floor because there weren’t enough chairs.
Note that we say:
– We didn’t have enough time. (not the time wasn’t enough)
– There is enough money. (not the money is enough)
You can use enough alone (without a noun):
– We don’t need any more money. We’ve got enough.
Compare too much/many and enough:
– There’s too much furniture in this room. There’s not enough space.

We say enough/too … for somebody/something
– We don’t have enough money for a vacation.
– Is Joe experienced enough for the job?
– This shirt is too big for me. I need a smaller size.
But we say enough/ too … to do something (not for doing). For example:

– Is Joe experienced enough to go on vacation. (not for going)
– They’re too young to get married. / They’re not old enough to get married.
