Components of a sentenceClausesA clause consists of a subject and a predicate. The subject is typically a noun phrase, though other kinds of phrases (such as gerund phrases) work as well, and some languages allow subjects to be omitted. The predicate is a finite verb phrase: a finite verb together with zero or more objects, zero or more complements, and zero or more adverbials.There are two types of clauses: independent and subordinate (dependent). An independent clause demonstrates a complete thought; it is a complete sentence: for example, "I am sad." A subordinate clause is not a complete sentence: for example, "because I had to move."See also copula for the consequences of the verb to be on the theory of sentence structure.Complete sentencesA simple complete sentence consists of a single clause (subject and predicate). Other complete sentences consist of two or more clauses (see below).
