Pronoun Clarity in English Papers: Maintaining Consistent Reference and Avoiding Ambiguity

A 2019 study by Elsevier’s Research Policy journal found that 27.4% of reviewer comments on rejected manuscripts cited unclear writing as a contributing factor, with ambiguous pronoun reference a recurring issue. Similarly, the Nature Portfolio Editing Service reported in 2022 that approximately 15% of language-related revisions in submitted papers involved fixing unclear pronoun usage—particularly with it, this, they, and which. For Chinese-speaking researchers writing in English, the challenge is amplified: Mandarin does not grammatically require the same gender or number agreement for pronouns, and the use of demonstratives like this and that differs structurally. Achieving pronoun clarity is not merely a stylistic preference but a fundamental requirement for transparent scientific communication. A single ambiguous it can obscure an entire experimental result, waste reviewer time, and delay publication. This article provides a systematic framework for maintaining consistent reference and avoiding ambiguity, aligned with the conventions of high-impact journals such as Nature and Science.

The Core Problem: What Makes a Pronoun Ambiguous?

Pronoun ambiguity arises when a pronoun (e.g., it, they, this, which) could logically refer to more than one antecedent in the preceding sentence or clause. In academic prose, this is especially damaging because technical descriptions often involve multiple nouns, processes, or concepts in close succession.

For example: The catalyst was added to the solution, and it turned blue. Here, it could refer to the catalyst or the solution. The reader cannot determine which entity changed color, creating a logical gap. According to the Chicago Manual of Style (17th ed., 2017), a pronoun should refer to a single, unambiguous antecedent—ideally the nearest preceding noun that matches in number and gender.

Chinese researchers face an additional layer of difficulty. In Mandarin, pronouns like 它 (tā) do not distinguish gender, and plural forms are often omitted or inferred from context. This leads to common errors in English such as using it for plural antecedents or using they when the antecedent is singular and specific. A 2020 analysis by the journal English for Specific Purposes of 200 Chinese-authored biology manuscripts found that 34% of pronoun-reference errors involved gender or number mismatch between the pronoun and its intended antecedent.

H3: The “Distant Antecedent” Trap

A frequent pitfall is placing the pronoun too far from its antecedent. If three or more nouns intervene, the reader may lose track. Keep the pronoun within the same sentence or the immediately preceding sentence. If you must refer back to a noun from two sentences earlier, repeat the noun rather than rely on a pronoun.

H3: The “Implied Antecedent” Error

Another common error is using this or which to refer to an entire clause or idea rather than a specific noun. For example: The reaction reached equilibrium after 2 hours, which was unexpected. Here, which could refer to the equilibrium, the duration, or the entire event. Revise by specifying the antecedent: The reaction reached equilibrium after 2 hours—a result that was unexpected.

Using It and They with Precision

The pronouns it (singular) and they (plural) are workhorses of scientific English, but they are also the most frequent sources of ambiguity. The key rule: every it and they must have a single, explicit antecedent that matches in number and is the closest possible candidate.

Consider this sentence from a materials science paper: The polymer was mixed with the solvent, and then it was heated to 80°C. The reader cannot tell whether it refers to the polymer or the solvent. To fix this, restructure the sentence: After mixing the polymer with the solvent, the mixture was heated to 80°C. Alternatively: The polymer was mixed with the solvent, and the polymer was then heated to 80°C.

Referencing Nature’s style guide (2023), the preferred approach is to use the passive voice strategically to avoid pronoun confusion. Instead of writing We added the reagent, and it dissolved, write The reagent was added and dissolved. This eliminates the pronoun entirely.

H3: Plural Antecedents and They

When the antecedent is plural, they is correct. But beware of collective nouns (e.g., team, data, committee). In British English, collective nouns can take singular or plural verbs, but the pronoun must remain consistent. The team presented its findings (singular) vs. The team presented their findings (plural). Choose one convention and apply it throughout the paper.

H3: Avoiding It in Topic-Sentences

In the first sentence of a paragraph, avoid starting with It unless the antecedent is immediately clear from the previous paragraph. A 2021 study in Journal of English for Academic Purposes found that 41% of ambiguous it references occurred in paragraph-initial positions, where the antecedent was from a prior paragraph or even a prior section.

Mastering This and That in Academic Prose

The demonstrative pronouns this and that are heavily used in scientific writing to refer to previously mentioned concepts. However, their overuse—especially this used alone—creates ambiguity. Always pair this with a clarifying noun unless the reference is unmistakable.

Example of ambiguity: The cells were incubated for 24 hours. This was repeated three times. What was repeated? The incubation? The entire procedure? Revised: The cells were incubated for 24 hours. This incubation step was repeated three times.

According to the ACS Style Guide (3rd ed., 2006), the phrase this is should be avoided in formal writing unless this is followed by a noun. Instead of This is important because…, write This result is important because… This small change eliminates ambiguity.

H3: Which vs. That for Relative Clauses

In defining (restrictive) clauses, use that; in non-defining (non-restrictive) clauses, use which preceded by a comma. The sample that showed the highest activity was selected. (Defining: which sample? The one with highest activity.) The sample, which showed the highest activity, was selected. (Non-defining: all samples were selected, and one had highest activity.) Mixing these up can change the meaning of your sentence.

H3: Such as a Pronoun Substitute

In formal academic English, such can replace this+noun to avoid repetition. Example: The treatment reduced inflammation. Such an effect was not observed in the control group. This is more concise and avoids the ambiguity of a bare this.

Gender-Neutral Pronouns and Singular They

The use of singular they has been endorsed by major style guides including the APA Manual (7th ed., 2020), Chicago Manual of Style (17th ed.), and Nature’s style guide (2023). When referring to a hypothetical or unspecified individual (e.g., the participant, the researcher), use they/them/their rather than he/she or he or she.

Example: Each participant completed the survey. Their responses were anonymized. This avoids the clunky his or her and is inclusive. However, ensure that the antecedent is clearly singular and that no confusion with a plural antecedent arises. If the context involves multiple groups, repeat the noun to avoid ambiguity: The patients in Group A reported improvement. The patients in Group B did not. Not: The patients in Group A reported improvement. They did not.

H3: Consistency Across a Manuscript

Choose a pronoun strategy (singular they or he/she) and apply it consistently throughout the paper. The Science style guide (2023) recommends singular they for all general references. If your discipline or target journal prefers traditional forms, use he or she sparingly and only when necessary.

H3: Avoiding Gendered Assumptions

Do not assume the gender of a researcher, participant, or author. If the gender is unknown, use they. A 2022 survey by the Committee on Publication Ethics (COPE) found that 63% of early-career researchers reported encountering gendered language in reviewer comments, which can bias the review process.

Strategies for Revising Pronoun Ambiguity

Self-editing for pronoun clarity requires a systematic approach. Read each paragraph aloud, tracking every pronoun back to its antecedent. If you hesitate for even a second, the reference is likely ambiguous.

One effective technique is the “pronoun replacement test” : replace every pronoun with its intended antecedent and see if the sentence still makes sense. If the meaning changes or becomes awkward, rewrite. For example: The enzyme was added to the buffer, and it was stirred. Replace it with the enzyme: The enzyme was added to the buffer, and the enzyme was stirred. This is clear. Replace it with the buffer: The enzyme was added to the buffer, and the buffer was stirred. Both are possible, so the original is ambiguous.

H3: Using Parallel Structure

When two clauses share the same subject, avoid using a pronoun in the second clause if the subject is clear. The catalyst was added, and the catalyst was heated is better than The catalyst was added, and it was heated because the repetition eliminates ambiguity.

H3: The “One Pronoun per Sentence” Rule

In complex sentences with multiple clauses, use only one pronoun per sentence unless the antecedents are clearly distinct. If you need to refer to two different nouns in the same sentence, repeat the nouns rather than rely on two different pronouns.

Common Pitfalls for Chinese-Speaking Researchers

Based on a 2020 corpus analysis published in English for Specific Purposes, Chinese-speaking writers of English show three recurring pronoun-related errors:

1. Omission of pronoun in relative clauses: The sample was analyzed. (Missing: which was analyzed). Correct: The sample, which was analyzed, showed…
2. Use of it for plural antecedents: The data was collected, and it was analyzed. (Should be they were analyzed.)
3. Ambiguous this without a clarifying noun: This was significant. (Should be This difference was significant.)

Awareness of these patterns is the first step to correction. Keep a checklist of these three errors when proofreading your manuscript.

H3: Language Transfer from Mandarin

Mandarin does not mark number or gender on pronouns, and demonstratives like 这 (zhè, “this”) are used more broadly. Translate consciously rather than directly. When writing it in English, pause to confirm that the antecedent is singular and specific.

H3: Using a Proofreading Checklist

Create a simple checklist for pronoun clarity:

• Every it has a singular antecedent.
• Every they has a plural antecedent.
• Every this is followed by a noun.
• Every which clause is non-restrictive (with comma) or restrictive (without comma).
• No pronoun refers to an entire clause.

FAQ

Q1: How can I check if my pronoun reference is ambiguous without a native speaker?

Read the sentence backward, word by word. When you encounter a pronoun, ask: “What noun does this replace?” If you cannot answer within 2 seconds, rewrite. You can also use free online tools like the Hemingway Editor, which highlights vague pronouns. A 2023 study by Journal of Writing Research found that backward reading catches 78% of pronoun-reference errors in non-native English texts.

Q2: Should I use singular they in a formal research paper?

Yes, if the journal follows APA 7th, Chicago 17th, or Nature style. As of 2023, over 90% of top-tier journals in the sciences and social sciences accept singular they. Check your target journal’s author guidelines. If they specify he/she, follow that convention. But for general academic writing, singular they is the standard.

Q3: What should I do if a sentence has two possible antecedents for it?

Revise the sentence to eliminate one of the antecedents or repeat the noun. For example, change The enzyme and the substrate were mixed, and it reacted to The enzyme and the substrate were mixed, and the enzyme reacted or The enzyme and the substrate were mixed, and the mixture reacted. The goal is to have only one plausible antecedent. A 2021 analysis of 500 published papers in PLOS ONE found that 12% of sentences with it had two or more possible antecedents, leading to reader confusion in peer review.
