Here's how linking verbs function in a sentence:
Subject
+ Linking Verb
+ Subject Complement
The subject complement is a noun, pronoun, or adjective that follows the linking verb and provides more information about the subject.
It completes the meaning of the sentence by describing or identifying the subject.
Example with an adjective complement:
She
is happy.
The linking verb
is connects the subject
she with the adjective complement
happy describing her state of being.
Example with a noun complement:
He
is a doctor.
The linking verb
is connects the subject
he with the noun complement
doctor identifying his profession.
