How do you use pronouns as subject complements?

Pronouns can function as subject complements when they refer back to the subject of the sentence and provide more information about the subject's identity or state of being. Here's how it works:

Subject Complement Structure:

* Subject + Linking Verb + Subject Complement

Pronouns as Subject Complements:

* Personal Pronouns:

* "It is I who am responsible." (I refers back to the subject "it")

* "The person at the door is she." (she refers back to the subject "person")

* Reflexive Pronouns:

* "The student who aced the test was himself." (himself refers back to the subject "student")

* "The cat washed itself." (itself refers back to the subject "cat")

* Demonstrative Pronouns:

* "The problem is that." (that refers back to the subject "problem")

* "The winner is this." (this refers back to the subject "winner")

Examples:

* "The winner of the contest is he." (He is the subject complement, identifying the winner)

* "My favorite author is she." (She is the subject complement, describing the author)

* "The mystery guest was none other than her." (None other than her is the subject complement, revealing the identity of the guest)

* "The reason for the delay is it." (It is the subject complement, explaining the reason)

Important Note: In formal writing, it's generally preferred to use "I" or "he/she" after the linking verb "to be," rather than "me" or "him/her." However, in informal speech, the use of object pronouns is more common.

Summary:

Subject complements provide more information about the subject of a sentence. Pronouns can act as subject complements, referring back to the subject and identifying or describing its identity or state of being.
