What Are Subject Complements?

'Subject complements' (also known as predicative adjectives) are words or phrases that follow linking verbs and complete the meaning of the clause by describing the subject of the clause. Subject complement provides a description of the subject.

Adjective Phrases as Subject Complements

Adjective phrases can consist of one or more adjectives. They can be placed after linking verbs to provide additional information and complete the description of the subject.

Noun phrases can consist of a single word or multiple words. They can be used as subject complements in a clause, providing additional information about the subject of the sentence. Take a look at the examples:

Adverb Phrases as Subject Complements

While adverb phrases can be used as subject complements following linking verbs, it is important to note that if an adverb can be easily removed from the sentence without affecting the meaning, then it is not acting as the subject complement. For example:

She was upstairs.

His mother is out.
