English is not a grammatically gendered language like French or German — but that doesn’t mean gender plays no role. Mistakes involving pronouns (he/she/they), possessives (his/her/their), and reflexive forms (himself/herself/themselves) remain among the most frequent errors in writing and speech.
Whether you’re a student, professional writer, non-native speaker, or content creator, mastering gender agreement signals clarity, respect, and professionalism. This guide — the only one you’ll ever need — covers every rule, trap, and fix.
A gender grammatical mistake occurs when a pronoun, possessive, or reflexive does not match the gender (or lack thereof) of the noun it refers to. Because English lacks noun classes (unlike Spanish or Arabic), errors usually involve pronoun-antecedent agreement and assumed gender.
Example of an error:
❌ Each student must bring his own lunch.
✅ Each student must bring their own lunch.
For centuries, English style guides prescribed he as the default pronoun for a person of unknown gender. Today, that usage is considered outdated and often incorrect.
| Mistake | Correction |
|---|---|
| Anyone can succeed if he works hard. | Anyone can succeed if they work hard. |
| A teacher should respect his students. | Teachers should respect their students. |
EEAT Note: This change is supported by virtually all modern style guides (APA, Chicago, MLA, AP) and major dictionaries.
Indefinite pronouns like everyone, somebody, no one are singular in form but often refer to people of any gender.
❌ Someone left his wallet. (implies the person is male)
✅ Someone left their wallet. (neutral, correct)
❌ Nobody should blame himself for the delay.
✅ Nobody should blame themselves for the delay.
Reflexive pronouns must agree with the subject’s gender and number.
| Incorrect | Correct | Reason |
|---|---|---|
| Everyone did it by theirselves. | Everyone did it by themselves. | Theirselves is nonstandard. |
| The CEO herself attended. (CEO is male) | The CEO himself attended. | Match actual gender. |
| The team congratulated itself. (team as people) | The team congratulated themselves. | Collective noun acting as individuals. |
Never assume a nurse is female, an engineer is male, or a teacher is non-binary unless stated.
❌ A doctor must listen to his patients.
✅ Doctors must listen to their patients.
✅ A doctor must listen to their patients. (singular they)
❌ The secretary typed her notes quickly.
✅ The secretary typed the notes quickly. (omit pronoun) or their notes.
When referring to a specific person who uses non-binary pronouns (e.g., they/them), use themself (singular) or themselves (plural depending on context).
❌ Alex hurt himself. (if Alex uses they/them)
✅ Alex hurt themself.
Note: Themself is accepted in modern English for singular they.
Shifting between he, she, and they for the same person confuses readers.
❌ If a student is late, he should report to the office. Then they will get a pass.
✅ If a student is late, they should report to the office. Then they will get a pass.
The singular they is not new (Chaucer and Shakespeare used it). It refers to a single person whose gender is unknown, irrelevant, or non-binary.
When to use singular they:
| Situation | Example |
|---|---|
| Gender unknown | The caller said they would call back. |
| Generic person | Anyone can learn if they try. |
| Non-binary individual | Jordan brought their laptop. |
Common objection: “But they is plural!”
Fact: Every major English dictionary and style guide now accepts singular they. It was named Word of the Year (2015) by the American Dialect Society.
Use it or its for a unit acting together; use they/them/themselves for members acting individually.
The team celebrated its victory. (team as one)
The team celebrated themselves after the game. (individual players)
English does not gender animals or objects unless specified. Avoid she for ships or he for nations unless stylistically intentional (and consistent).
❌ The dog lost his collar. (unknown sex)
✅ The dog lost its collar.
Use the person’s preferred pronouns. When unknown, use they or restructure.
❌ The ambassador will present his credentials.
✅ The ambassador will present their credentials.
✅ The ambassador will present the credentials.
| Antecedent | Correct Pronoun(s) | Example |
|---|---|---|
| A person (gender unknown) | they / them / their / themselves | Someone forgot their phone. |
| A specific man | he / him / his / himself | John fixed it himself. |
| A specific woman | she / her / hers / herself | Maria baked it herself. |
| A specific non-binary person | they / them / their / themself | Taylor bought themself a gift. |
| A collective noun (unit) | it / its / itself | The jury reached its verdict. |
| A collective noun (individuals) | they / them / their / themselves | The jury took their seats. |
Use plural nouns – Change “A student must bring his book” to “Students must bring their books.”
Omit the pronoun – “The manager should listen to his team” → “The manager should listen to the team.”
Repeat the noun – “Ask the user for his password” → “Ask the user for the user’s password.”
Use singular they – The simplest, most inclusive solution.
Ask or confirm – When writing about a real person, use their stated pronouns.
| Myth | Truth |
|---|---|
| “Singular they is incorrect grammar.” | Used for over 600 years; accepted by all major authorities. |
| “Always use he or she to be safe.” | Clunky and excludes non-binary people. Singular they is smoother. |
| “Animals are always it.” | Fine for unknown sex, but use he/she if known and relevant. |
| “English has no gender.” | English has natural gender (pronouns), not grammatical gender for nouns. |
If your first language assigns gender to objects (e.g., Spanish el libro masculine, la mesa feminine), remember:
English nouns have no gender – a table is it, not she.
People’s professions have no gender – doctor, teacher, nurse take they unless specified.
Common ESL error:
❌ I bought a new car. She is red.
✅ I bought a new car. It is red.
