In previous Chapter, we learned that transitive verbs can be followed by a noun, a to-infinitive, a gerund, a that-clause, and a wh-clause as object. These verbs, which take one object to make a predicate, are called monotransitive verbs. In addition, some transitive verbs might simultaneously take two objects to make a predicate: a direct object (Od) and an indirect object (Oi). Verbs of this type are called ditransitive verbs. Study this chapter critically.
