ENOUGH AND TOO


ENOUGH
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.

Enough normally goes before nouns:

We have enough money. We don’t need any more.
There weren’t enough chairs. Some of us had to sit on
the floor.

We also use enough alone (without a noun or adjective):

We don’t need more money. We have enough.


TOO AND 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)

Compare too much/many and enough:

There’s too much furniture in this room. There’s not enough space.
There were too many people and not enough chairs.

ENOUGH/TOO + TO …

We say enough/too … to do something. 
For example:
Does Joe have enough experience to do the job?
Let’s get a taxi. It’s too far to walk home from here.
She’s not old enough to have a driving licence.

The next example has both for … and to … :

The bridge is just wide enough for two cars to pass one another.

TOO HOT TO EAT ETC.

We say:
The food was very hot. We couldn’t eat it.
and
The food was so hot that we couldn’t eat it.
but
The food was too hot to eat. (not to eat it)

In the same way we say:

These boxes are too heavy to carry. (not to carry them)
The wallet was too big to put in my pocket. (not to put it)
This chair isn’t strong enough to stand on. (not to stand on it)
