Many verbs can be followed by an object. These verbs are called transitive verbs. In fact, some verbs must have an object (e.g., "take"), but some verbs never take an object (e.g., "sleep"). Verbs that do not take an object are called intransitive verbs. Some verbs can even have two objects. They are called ditransitive verbs. In the following examples, the object is underlined and the primary verb is in bold.
