He or she, his or her? Why Spanish speakers mix them up even when they know better

You're on a video call with the Chicago team, explaining that your manager, Sarah, signed off on the budget. Out comes "He approved it this morning". Nobody corrects you, but someone frowns at their screen. You know perfectly well that she means ella. So what happened?

Spanish speakers make two separate slips in English, he/she and his/her, with two separate causes, and neither one is a knowledge gap. The he/she slip happens because Spanish rarely says the subject: aprobó el presupuesto never forces you to decide whether it was a man or a woman. The his/her slip happens because Spanish possessives agree with the thing owned, so a gendered noun like brother drags the English word along: Mary loves his brother. Both slips show up when you speak in real time, not on a test. The fix pairs a one-line rule with a lot of practice out loud.

Why do I say he when I'm talking about a woman?#

Spanish drops the subject, and that leaves gender out of the sentence plan. Spanish speakers say the subject pronoun in a minority of cases: 21% in Spain and an average of 24% in mainland Latin American Spanish. Even the Caribbean, where it's most common, averages 38%. You rarely practice choosing between él and ella, and English demands that choice every time you talk about someone.

Spanish speakers mix up he and she far more than French speakers at the same level. In an experiment with 20 Spanish speakers and 20 French speakers answering spoken questions about pictures, the Spanish group made gender errors on 4.30% of he/she uses, compared with 0.68% for the French group. French, like English, always states the subject. The study's author, Inés Antón-Méndez, puts it plainly: "even very proficient Spanish-English L2 speakers seem to confound the two pronouns, calling husbands she and mothers he". In her words, these errors "are not due to lack of knowledge".

The slip happens in the moment of speaking, not in your grammar. A team at Radboud University simulated it with two computer models: the one that learned a version of Spanish without dropped subjects made almost no pronoun errors (0.11% at most), while the one that learned real Spanish started at 9.75% and never reached zero. Their explanation: dropping subjects leaves gender weak in your sentence plan, and at full speed the "it's a woman" signal loses the race to your mouth.

Back on the Chicago call:

Wrong: "Sarah checked the numbers, and then he approved the budget."
Right: "Sarah checked the numbers, and then she approved the budget."

Why do I say his when the owner is a woman?#

Norman Coe blames su first in Learner English, Cambridge's reference guide for teachers: "Spanish and Catalan have the same word for your (formal), his, her and their, with consequent confusion in English".

The deeper cause goes beyond su having no gender: Spanish possessives agree with the thing owned, not the owner. In a 2011 study, Antón-Méndez compared speakers of Dutch, Italian, and Spanish. The Spanish speakers made the same errors as the Italians, whose suo/sua does mark gender, mostly when the thing owned was a person, like mother. In a separate experiment, errors reached 12.1% with gendered people nouns, versus 3.6% with people nouns that work for either sex.

Say you're telling a coworker in Toronto that your friend Marta is coming to the barbecue with her husband:

Wrong: "Marta is bringing his husband."
Right: "Marta is bringing her husband."

Husband is masculine, so your Spanish-wired brain reaches for his. In English, Marta picks the word, because she's the owner. It works in reverse too: Pedro called her mother when you mean Pedro's own mother.

Many learners lean toward his. In a 2023 study of 43 Spanish speakers living in London, masculine slips made up 36.3% of errors, versus 15.7% for feminine ones. Objects barely cause trouble: mistakes with his hit 31.2% with animate nouns and just 4.6% with inanimate ones. You'll rarely flub her job; her brother is where you trip.

You know it, but it slips out when you speak#

Your grammar is fine; what's missing is automaticity. Participants in the London study filled out a questionnaire on possessives first and scored at ceiling, yet kept slipping in the speaking task. Lucia Pozzan and Inés Antón-Méndez reached the same conclusion: the pull toward agreeing with the nearby noun is specific to production.

A higher level cuts these errors but doesn't erase them. Antón-Méndez puts it this way: "even proficient L2 speakers are susceptible to the influence of automatic processes that should apply in their first language alone". In the London study, advanced speakers made fewer errors overall, but proficiency didn't reduce the errors where her was needed.

It's not a Spanish-speaker flaw#

Mixing up his and her isn't unique to Spanish. Pozzan and Antón-Méndez describe the same local-agreement pattern in Mandarin-speaking learners and in English-speaking children. The he/she slip is typical of languages that drop the subject: the Radboud team notes it also shows up in Italian speakers.

How to stop mixing them up: one short rule and a lot of talking#

The his/her rule fits on one line: look back at the owner and ignore the noun that comes after. Owner is a man, his; a woman, her, whether the thing owned is a husband, a mother, or a car. The he/she rule is its sibling: before you open your mouth, lock in who's doing the action.

The rule works better with repeated practice. White, Muñoz, and Collins gave French-speaking and Catalan/Spanish-speaking teenagers a rule of thumb, contrastive information, and repeated practice in context, and the students made progress with his/her even with only a few hours of English a week.

Could you tell someone right now, out loud, what your sister did last weekend with her boyfriend? That automatic recall is exactly what Tabla trains: short phrases you say out loud, with speech recognition scoring each attempt, until they come out on their own.

You're telling a friend in Denver that your aunt Rosa called her son. Is it Rosa called his son or Rosa called her son?

Rosa called her son. The owner is Rosa, a woman, so it's her, even though son is masculine.

Next time you talk about someone in English, before the possessive, ask yourself whose it is, not what it is.

Try this today: spend one minute describing three women in your life and their families out loud (her husband, her son, her brother), record it, and count how many times his slips out.
