Verb Patterns

Some verbs are followed by verb + ing (e.g. enjoy, mind, keep, admit, recommend, suggest)

The negative form is not + verb + -ing

Other verbs are followed by to + infinitive (e.g. want, promise, hope, agree, offer, need, refuse threaten, plan)

Some verbs can be followed by both patterns (e.g. start, begin, continue) with no change of meaning

Some verbs can be followed by both patterns, but the meanign changes (e.g. try, forget, remember)

Some verbs need an object before to + infinitive (e.g. advise, invite, ask, remind, tell, want)

When a verb comes after a preposition (e.g. about, by, of) the verb is always in the -ing form

Infinitive or purpose

Adjective + to + infinitive

Verb + question word + to + infinitive
