7.3 Enough and too

Rule: Enough and too in comparative expressions are followed by an infinitive clause, tot by a that clause.

Examples of errors:

(1) This approach is too much centered upon life in America that it can have a real impact on the European reader.
(2) He's not strong enough that he can lift it.

As mentioned in 7, enough and too are used in comparative expressions to indicate a relationship between two items that can be described as 'sufficiency' and 'excess'. The comparative elements whether it be an adjective, adverb, or noun phrase, is followed by an infinitive clause (not a that clause, as in (1)); this clause may be omitted when context allows, e.g.:

Want to go swimming?
No, it's too cold (to go swimming).

or

Yeah, I guess it's warm enough (to go swimming).

The subject of the infinitive clause may be introduced by

for:

It's too cold for us to go swimming.
