What Are Subject Complements in English?

What Are Subject Complements?

'Subject complements' (also known as predicative complements) are special types of verb complements 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.

Subject Complements: Types

There are five types of subject complements in English:

Adjective Phrases as Subject Complements

Adjective phrases can consist of one or more adjectives and their modifiers, such as adverbs or prepositional phrases. They can be placed after linking verbs to provide additional information and complete the description of the subject.
Check out the examples:

Example

The walls are green.

It will get quite small when you fry it in oil.

Noun Phrases as Subject complements

Noun phrases can consist of a single noun or a noun and all its modifiers, e.g., determiners, adjectives, prepositional phrase, and noun modifiers. 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:

Example

It seems a long time since I have seen you.

My favorite animals are sea horses.

Pronouns as Subject Complements

Pronouns can also act as subject complements following linking verbs. There are various types of pronouns that can be used in this way, including:

Check out the examples:

Example

The big problem is this. → demonstrative pronoun

It was me calling for help. → object pronoun

It was I calling for help. → subject pronoun

This use of subject pronouns is old fashioned and uncommon.

The teacher is who? → (interrogative pronoun)

She's someone I knew back in college. → (indefinite pronoun)

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:

Example

She was upstairs.

His mother is out.

Noun Clauses as Subject Complements

A noun clause functioning as a subject complement is a type of clause that follows a linking verb and serves to complement the subject by providing information about it. For example:

Example

The question is who will lead the team.

Her belief is that honesty is the best policy.
