Ambiguous pronoun antecedents and how to fix them

Pronouns keep writing from sounding repetitive, but they work only when readers can identify what each pronoun means. If two nouns could fit, or the intended antecedent is too far away, a reader may assign the pronoun to the wrong person or idea. This is a clarity problem even when the sentence is technically grammatical.

Spot competing antecedents

Consider: “When Lena spoke with Morgan, she said the report was late.” The reader cannot know whether “she” means Lena or Morgan. The pronoun agrees grammatically with both names, so agreement alone cannot resolve the ambiguity. Repeat the intended name: “Lena told Morgan that the report was late,” or “Morgan told Lena that the report was late.”

Make vague this and that specific

A sentence-initial “this,” “that” or “it” can refer to an entire preceding thought without naming which point matters. For example, “The supplier missed two deadlines. This caused concern” is vague if several effects are possible. “The missed deadlines caused the project team to question the delivery schedule” identifies the cause and effect directly. Adding a noun after “this” often clarifies the reference: “This delay…” or “This cost increase…”

Check distance and number

Even a single possible antecedent can become hard to follow if several sentences separate it from the pronoun. Repeat the noun when the reader has to search backward. Also check number: “The committee submitted their report” may be acceptable in some varieties and contexts, but formal U.S. exam editing typically expects a singular pronoun when the group is treated as one unit, or a rewrite that avoids the issue. The antecedent and pronoun must communicate the same intended referent.

A quick revision method

1. Circle every he, she, it, they, this, that and which.
2. Draw an arrow to the intended antecedent.
3. If more than one noun is plausible, rewrite the sentence with the intended noun.
4. If the reference is distant, repeat or restate the noun near the pronoun.
5. Check that the pronoun agrees in person and number and that the revised sentence preserves the intended meaning.

Common traps

• A pronoun can be grammatically matched to two different names and still be unclear.
• A vague pronoun may refer to an entire clause rather than one noun.
• Do not make readers infer the referent from context when one clear noun would solve the problem.
• Changing a pronoun to a noun may improve precision even if it repeats a word.
• Do not confuse ambiguous reference with pronoun case: the form may be correct while the reference is unclear.

Key takeaway

Ask what each pronoun points to. If a reader can reasonably choose between two antecedents, name the intended person or idea and revise the sentence around it.

Look for competing nouns before the pronoun

A pronoun has an ambiguous antecedent when two or more nouns could reasonably be its referent. “When Eli called Jordan, he sounded worried” does not make clear whether Eli or Jordan sounded worried. Repeat the intended name or restructure: “Eli sounded worried when he called Jordan” or “Jordan sounded worried when Eli called.” The repair should identify the actor without changing who did what.

A pronoun can also be grammatically matched yet unclear because a plural antecedent sits among several nouns. “The report compared the survey with interviews, and they showed a difference” could refer to the survey and interviews together, the interviews alone, or the results. Replace they with the exact noun: “The survey and interviews showed a difference” or “The interviews showed a difference from the survey.”

Avoid broad this, that, and it references

Demonstrative pronouns such as this, that, and it can point vaguely to an entire preceding idea. “The plan was changed at the last minute, and this upset the team” is understandable but this has no specific noun antecedent. For more precise writing, name the event: “This last-minute change upset the team.” The word idea or situation can help when the reference is truly a whole proposition, but do not add a vague filler noun automatically.

A pronoun beginning a sentence can be unclear when the prior paragraph contains several possible referents. Repeat the noun at a paragraph transition, especially in technical writing where several processes or groups have been discussed. Repetition is not always clumsy; it can be the shortest route to clear reference.

Keep number and meaning aligned

A pronoun should agree with its antecedent in number and person, but agreement alone does not guarantee clarity. “The committee sent its report after it reviewed the data” has singular it for both committee and report; readers may momentarily attach the second it to the report. A clear version names the actor: “After the committee reviewed the data, it sent its report.” If ambiguity remains, repeat committee.

When a sentence mentions a person and a possession, watch for possessive pronouns that could refer to either person. Recast the sentence to identify the owner. Use each pronoun’s grammatical form correctly and maintain the person’s stated pronouns when the antecedent is an individual.

• List every plausible antecedent for an unclear pronoun.
• Repeat the intended noun or reorganize the sentence.
• Replace vague this/that/it with a precise noun when helpful.
• Check both agreement and meaning; one does not guarantee the other.
• Reintroduce key nouns after long passages or paragraph breaks.

Use a clear noun when two references compete

When two nouns could be the antecedent, agreement alone may not resolve the ambiguity. “Jordan told Alex that he needed more time” leaves the reader to guess who needed it. Repeating the name is often the cleanest repair: “Jordan told Alex, ‘I need more time,’” or “Jordan told Alex that Alex needed more time.” A rewrite can also remove the pronoun: “Jordan asked Alex for more time.” Choose the version that preserves the intended relationship and point of view.

Vague this, that, and it also need attention when they refer to a whole idea rather than a nearby noun. “The class changed the schedule, and this caused confusion” is understandable, but “The schedule change caused confusion” names the cause. In reading questions, look backward for the nearest grammatically and logically possible antecedent, then test whether another noun also fits. If the reference remains uncertain, the passage may be deliberately imprecise; do not invent certainty that the text does not supply.
