October 2026 - Pronouns Study Guide

The three cases

The removal test

Case errors nearly always happen when a pronoun is paired with someone else. "The consultant thanked Maria and I" sounds careful, and is wrong. Remove Maria: "the consultant thanked I". The ear settles it immediately, so the correct version is "Maria and me".

The test works in both directions. "Maria and me reviewed the notes" becomes "me reviewed the notes", which is equally wrong, so it should be "Maria and I". Neither form is automatically more correct — the test tells you which is needed.

Agreement with the antecedent

The antecedent is the noun the pronoun stands for. They must match in number and person.

• Singular antecedent, singular pronoun: Each nurse collected her own equipment, or the widely accepted singular their.
• Watch indefinite pronouns: everyone, each, either, neither, somebody and nobody are grammatically singular.
• Collective nouns such as team, staff and committee are usually singular in American usage: the team submitted its report.
• Person must match too: do not start a sentence about "a student" and finish it with "you".

Vague and ambiguous reference

A pronoun with no clear antecedent is an error even when the grammar is otherwise sound.

• Ambiguous — The nurse told the patient that she had made a mistake. Who made it? Rewrite to name the person.
• Vague this or it — The system crashed and the notes were lost. This caused delays. What caused them? Add a noun: This failure caused delays.
• Missing antecedent — In the policy, it says handover must be documented. The policy says it; there is no "it" to refer to.

What the TEAS asks most

The same core ideas appear in different wording. If you can answer these without stopping to think, you have what this section requires.

Key points

• Three cases: subjective, objective, possessive.
• Remove the other person to test which case a paired pronoun needs.
• Pronouns must agree with their antecedent in number and person.
• Everyone, each and nobody are singular.
• Substitute he or him to choose between who and whom.
