infinitives (6): after adjectives reactions and feelings: pleased to see you
Infinitives are often used after adjectives describing reactions and feelings.
I'm pleased to see you.

Not all adjectives of this kind are followed by infinitives. Some are followed by preposition + -ing form (see 297), or by that-clauses (see 19). Some adjectives (e.g. afraid, sure) can be followed by either an infinitive or an -ing form, often with a difference of meaning: for details, see 299.
For structures with for (e.g. She's anxiolls for rile children to go home), see 291-293. other adjectives: certain to win
Besides adjectives referring to reactions and feelings, many other adjectives can be followed by infinitives. Examples: right, wrong, stupid, certain (see 299.15), welcome, careful, due, fit, able (see 3), likely (see 327), lucky.
