TOEIC Link Part 5: Pronoun Case — Choosing Between I/me, he/him, and they/them

A common TOEIC Link Part 5 question gives you one blank and four versions of the same pronoun: she, her, hers, herself. They all refer to the same person, so meaning will not tell you which is right. What decides the answer is the pronoun's grammatical job in the sentence — whether it is acting as a subject, an object, a possessor, or a reflexive. English keeps a different form for each job, and Part 5 tests whether you can identify the job quickly and match it to the form. This guide gives you the four cases, the one rule that picks between them, and the specific traps the test likes to set.

The four forms a pronoun can take

English personal pronouns change shape depending on their role. This is called case. There are four cases you need for Part 5:

Each column answers a different question, so the first move on any pronoun question is to ask: what is this pronoun doing in the sentence?

The one rule: identify the pronoun's job

• Subject case is for the doer of the verb — the thing performing the action. She approved the budget. If the blank comes before the main verb and is doing the action, it is a subject.
• Object case is for the receiver of an action or the object of a preposition. The manager promoted him. The package was sent to us. If the blank follows a verb (as its target) or follows a preposition like to, for, with, between, it is an object.
• Possessive case shows ownership. Use the determiner form before a noun (their report) and the standalone form when no noun follows (the decision was theirs).
• Reflexive case is used when the subject and the object are the same person. The director nominated himself. Here the doer and the receiver are identical, so the reflexive form is required.

Almost every Part 5 pronoun question is solved by locating the blank, asking which of these four jobs it is doing, and reading the matching form off the table. This is the same "find the job first" discipline that governs subject–verb agreement, where you must locate the true subject before you can choose the verb.

Trap 1: compound subjects and objects

The test's favorite trap is a pronoun joined to a noun or another pronoun with and. The join does not change the case — the pronoun keeps whatever form its job requires.

✗ The contract was signed by the client and I. ✓ The contract was signed by the client and me.

By is a preposition, so its object must be in object case: me, not I. The presence of the client and tempts you toward I because "the client and I" sounds polished, but politeness is not grammar. The reliable test is to delete the other person and read the pronoun alone: "signed by ... I" is clearly wrong, "signed by ... me" is right. This deletion trick resolves nearly every compound trap.

The same applies to compound subjects:

✓ She and I reviewed the figures. (both are subjects → subject case)

Delete the partner: "I reviewed the figures" works; "me reviewed the figures" does not.

Trap 2: "between you and I"

A specific high-frequency trap is the phrase _between you and __. Because _between is a preposition, both pronouns after it must be in object case: between you and me. "Between you and I" is one of the most common errors in business English, and Part 5 includes it precisely because so many test-takers have heard it and assume it is correct. Whenever a pronoun follows between, among, with, for, or to, reach for the object form.

Trap 3: possessive determiner vs possessive pronoun

When the answer choices include both their and theirs (or your/yours, her/hers), check whether a noun follows the blank:

• A noun follows → use the determiner form. Please update your records.
• No noun follows → use the standalone pronoun form. These records are yours.

This mirrors the determiner discipline tested across quantifiers and determiners: the word's form depends on whether it modifies a noun or stands in place of one.

Trap 4: reflexive used wrongly for emphasis

Reflexive forms (myself, themselves) are correct only when the subject and object are the same. Test-writers offer a reflexive as a distractor in sentences where a plain object is needed:

✗ Please send the report to myself. ✓ Please send the report to me.

The sender and the receiver are different people here, so no reflexive is justified. Use a reflexive only when you can point to a subject earlier in the clause that the pronoun loops back to: I taught myself the software (I = myself).

A three-second decision process

1. Find the blank and its job. Is the pronoun doing the action (subject), receiving it or following a preposition (object), showing ownership (possessive), or looping back to the subject (reflexive)?
2. If it is part of a compound, delete the partner and read the pronoun alone to hear the correct case.
3. For possessives, check for a following noun to choose determiner vs standalone.
4. For reflexives, confirm the subject and object are the same person before selecting one.

Run this process and the four near-identical choices collapse to one. Pronoun case rewards mechanical rule-following, not ear or instinct — which is exactly why building the habit pays off on test day.
