Some verbs refer to actions that produce a finished result. Examples are cut, build, pack, close. Other verbs do not: for example push, live, speak, hit, carry. The past participles of finished-result verbs, and some of their passive tenses, can have two meanings. They can refer to the action, or they can describe the result (rather like adjectives). Compare:
