  • Complex Sentence

    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.
