Excess and sufficiency followed by to plus verb.
Why you specifically
The rule
Too and enough are often followed by to + verb. Too goes before an adjective or adverb and means there is an excess, while enough usually comes after the adjective or adverb and means there is sufficient quantity, degree, or ability for the action. With nouns, enough can also come before the noun, but this lesson focuses on the infinitive pattern.
The trap
The box is enough heavy to carry.
The box is too heavy to carry.
Too + adjective + to + verb shows excess, so the action is not possible or practical.
She is too old to drive.
She is old enough to drive.
Enough comes after the adjective and before to + verb. Too means the opposite idea of excess.
The soup is enough hot to drink now.
The soup is too hot to drink now.
Too + adjective + to + verb means there is too much of the quality for the action to happen comfortably or safely.
He was enough tired to finish the homework.
He was too tired to finish the homework.
Too cannot be used with enough in this structure. Use too + adjective + to + verb for excess, or adjective + enough + to + verb for sufficiency.
