Verb complement

Verb Complements :
A Verb complement(notice the spelling of the word) is any word or phrase that completes the sense of a subject, an object, or a verb. As you will see, the terminology describing predicates and complements can overlap and be a bit confusing. Students are probably wise to learn one set of terms, not both.
•A subject complementfollows a linking verb; it is normally an adjective or a noun that renames or defines in some way the subject.
o A glacier is a huge body of ice.
o Glaciers are beautiful and potentially dangerous at the same time.
o This glacier is not yet fully formed. (verb form acting as an adjective, a participle)

Adjective complements are also called predicate adjectives; noun complements are also called predicate nouns or predicate nominatives.

•An object complementfollows and modifies or refers to a direct object. It can be a noun or adjective or any word acting as a noun or adjective.
o The convention named Dogbreath Vice President to keep him happy. (The noun “Vice President” complements the direct object “Dogbreath”; the adjective “happy” complements the object “him.”)
o The clown got the children too excited. (The participle “excited” complements the object “children.”)

•A verb complementis a direct or indirect object of a verb.
o Granny left Raoul all her money. (Both “money” [the direct object] and “Raoul” [the indirect object] are said to be the verb complements of this sentence.)
