Adjective & Adverbial Complements

 to Learning English

Complements are called complements because that is what they do--complete the sense of a subject, an object, or a verb.  There are three kinds of complements: subject complements, object complements, and verb complements.

1. Subject complements come after a linking verb*, and are adjectives, nouns, pronouns, or a word or groups of words acting as an adjective or a noun.  Subject complements define or describe the subject.   Subject complements can be predicate nouns (Jude is a philanderer), predicate adjectives (Martha is excited), or adverbial complements (The murdered is on the run).

*A linking verb is often a form of “to be.”  The verbs indicating the five senses may also be linking verbs (look, sound, smell, feel, taste), and sometimes verbs that reflect a condition or state of being (for example: appear, seem, become, grow, turn, prove, remain) act as linking verbs also.

Predicate adjectives and predicate nouns both follow linking verbs (verbs of sensation such as "feel," "look," "smell," "sound," "taste" or verbs of existence such as "act," "appear," "be," "become," "continue," "grow," "prove," "remain," "seem," "sit," "strand," "turn"). A predicate adjective is an adjective.  “Shelly is pretty.”—“pretty is an adjective describing “Shelly”.  A predicate noun (predicate nominative) is a noun.  “Will is an engineer”—“engineer” is a noun  describing “Will”.

 2. Object complements come after a direct object and describe, define, or refer to that object.  Object complements can be a noun, or an adjective, or any word functioning as a noun or an adjective.  Some verbs like “make, name, call, choose, elect, and appoint” often have object complements.  Object complements are not set off with commas.

  Usually verbs of perception, change, and judgment can cause their direct objects to take an object complement:  

 3.  Verb complements are direct or indirect objects of a verb.  Verb complements may be nouns, pronouns, or words or word groups acting as nouns.

        3a.  Adjective and Adverbial "complements" are also used.  They give the same information as an adjective or an adverb (where, when, how, how much) but are necessary to the meaning of the sentence.

Notice how leaving the adjective complement out would make the sentence seem incomplete.

Adverbial complements can only be placed:  1) after the verb and 2) after the object.
