Spanish vs French Gender: What's the Same, What's Different

If you speak one Romance language and you’re learning another, you have a huge head start with gender. Spanish and French share most of the same gender assignments — but not all. Knowing where they agree and where they diverge saves you from embarrassing mistakes.

The Good News: Most Words Share Gender

About 85-90% of cognates have the same gender in French and Spanish. If a word is masculine in French, it’s very likely masculine in Spanish too:

The shared Latin roots carry the same gender through to both modern languages.

Patterns That Work in Both Languages

Several ending rules apply to both French and Spanish:

Always feminine in both

• -tion / -ción: la nation / la nación
• -sion / -sión: la passion / la pasión
• -ure / -ura: la nature / la natura (Italian: la natura too)

Always masculine in both

• -ment / -mento: le moment / el momento
• -isme / -ismo: le tourisme / el turismo

If you’ve internalized these for one language, you can trust them for the other.

The Traps: Words That Flip Gender

Here’s where it gets interesting. Some common words are masculine in one language and feminine in the other:

These are the words that will trip up bilingual learners. Le lait is masculine in French but la leche is feminine in Spanish — there’s no logic to it, just historical drift from Latin.

Why Do They Differ?

Most gender flips happened because of sound changes over centuries. Latin had three genders (masculine, feminine, neuter). When the neuter disappeared, its nouns had to become either masculine or feminine — and French and Spanish sometimes made different choices.

Lac (milk) in Latin was neuter. French turned it masculine (le lait), while Spanish turned it feminine (la leche). Neither is “wrong” — they just evolved differently.

The “-e” Trap

In Spanish, words ending in -o are usually masculine and words ending in -a are usually feminine. French doesn’t have this luxury — plenty of masculine words end in -e (le livre, le monde, le musée).

Don’t apply Spanish gender intuition to French endings. Le monde (the world) ends in -e but is masculine. Le silence ends in -ence — a typically feminine pattern — but is masculine.

Cross-Language Strategy

If you’re learning both languages:

1. Trust shared patterns: -tion/-ción, -ment/-mento, -isme/-ismo all keep the same gender.
2. Flag the flippers: memorize the ~30 common words that change gender between the two languages.
3. Don’t guess from the other language for words that don’t share a root. French le lait tells you nothing about Spanish la leche.
4. Use cognates as anchors: if you know la nation is feminine in French, you can trust la nación in Spanish.

Compare Side by Side in Accord

Accord shows each word’s gender across all four Romance languages in a comparison table. When you look up chat (French: masculine), you can instantly see that gato (Spanish) is also masculine — or spot where the gender flips. It’s the fastest way to build cross-language gender intuition.
