Adjective + Preposition

Many adjectives are followed by a fixed preposition before a noun, a pronoun or an -ing form. No rule tells you which one, so learn them as pairs:

• in: interested in, involved in, rich in
• at: good at, bad at, terrible at (skills)
• of: afraid of, scared of, tired of, proud of, jealous of, full of, aware of
• to: married to, engaged to, kind to, polite to, similar to, allergic to
• for: famous for, responsible for, ready for, grateful for, good for / bad for (health)
• about: worried about, excited about, nervous about, crazy about, curious about

Note the contrast: She's good at tennis (a skill), but Exercise is good for you (healthy). After the preposition, a verb takes -ing: I'm tired of waiting. Say married to someone, never married with.
