Flexibility of the Sentence Elements

Although the sentence has a normal order—subject, verb, object; or subject, verb, complement—it is rich and varied in the possibilities it possesses of variety and rearrangement, especially in the position of adjective, participial, and adverbial elements, and in the case of adverb clauses.
