There are five types of subordinate clauses in English: the subject, the predicative, the attributive, the object and several types of adverbial clauses.

In English grammar, all the clauses are subdivided into three main groups: noun clauses, adjective clauses and adverb clauses.

The Noun clauses include three types of subordinate sentences such as the subject clause, the predicative clause and the object clause. Usually in subordinate clauses we use the direct word order but in some cases we may face a particular version of inversion. Also, different subordinate clauses need to be introduced by different introductory words which cannot be omitted.

All English verbs are divided into three big groups of transitive, intransitive and linking verbs. The belonging to one of these groups influences the choice of the object the verb may be followed by: direct, indirect, indirect without a preposition, prepositional object or the complex object. Another reason to know about "transitivity/intransitivity" of a verb is to be able to use the verb in the passive voice. In addition, some verbs such as get, grow, keep, look, and alike, can be also link verbs that will strongly influence the meaning of a sentence.

Practice using verbs that take an object + infinitive pattern, such as want, ask, tell, allow, and encourage. Learn when to use to + verb after the object and which verbs require a bare infinitive instead.
