What this is
Subject pronouns are the words that stand in front of a verb and say who is doing it: I, you, he, we. French has nine of them where English has seven, and the two extra ones are not decoration — they encode information English simply throws away.
Two things make this harder than swapping one word for another. French makes you choose between two words for you, based on your relationship with the person. And French has no it: every object is either il or elle, decided by the gender you learned with the noun.
The rule
| French | English | Notes |
|---|---|---|
| je (j’) | I | lowercase mid-sentence; elides to j’ before a vowel |
| tu | you | one person you are close to |
| il | he / it | a man, or any masculine noun |
| elle | she / it | a woman, or any feminine noun |
| on | we / one / people | takes a singular verb |
| nous | we | correct everywhere, formal in speech |
| vous | you | one person formally, or several people |
| ils | they | all-masculine or mixed groups, people or things |
| elles | they | all-feminine groups, people or things |
Notice what is not in that table: an equivalent of it. There is no gender-free option. If you are talking about a table, you say elle; if you are talking about a book, you say il. This is the single biggest habit shift in this concept, and it is why gender has to be learned with the noun rather than looked up later.
Why it works this way
French verbs used to carry enough information in their endings that the subject could be dropped, the way Spanish and Italian still do. As final consonants and vowels went silent, parle, parles and parlent collapsed into one identical sound, and the ending stopped being able to tell you who was speaking. The pronoun had to become obligatory to fill the gap. That is why French says je parle where Spanish is happy with hablo — the pronoun is now doing the work the ending can no longer do.
The same erosion explains on. It descends from the noun homme (man), used the way English used to say one does not do that. Because it started life as a noun, it takes a third-person singular verb — and it has kept that verb form even after everyday speech quietly promoted it to the ordinary word for we.
Edge cases
on takes a third-person singular verb but usually means “we”
On va au cinéma means we’re going to the cinema, not one goes to the cinema. In conversation, on has almost entirely replaced nous as the subject: French speakers say on mange, on parle, on regarde. But the verb never changes shape to match the meaning — it stays in the il/elle form. On mangeons is not a thing. Write on mange, and hear it as we eat.
Nous has not disappeared. It survives in writing, in speeches, in careful or formal registers, and in the emphatic form nous, on…. Learn to produce on and to recognize nous.
vous is both formal singular and plural; only context distinguishes them
Vous préférez le café ? can be one person you have just met, or five people in a room. Nothing in the sentence tells you which. Being wrong in the other direction has consequences, though: using tu with a stranger, a shopkeeper, or someone much older reads as either rude or oddly intimate. Default to vous with anyone you have not been invited to tutoyer, and switch when they switch.
A mixed group takes ils regardless of proportion
Ninety-nine women and one man is ils. The masculine form covers mixed company, so elles only survives when every single member of the group is feminine — and adding one masculine noun to the list switches the pronoun for the whole sentence. This applies to objects too: les chaises et les livres is ils, because livres is masculine.
il and elle are not only “he” and “she”
Le stylo ? Il est là. — The pen? It’s over there. Objects keep the gender of their noun when they turn into pronouns, so il is doing the job English gives to it. In the plural, the same logic gives you ils for masculine objects and elles for feminine ones. The pronoun is chosen by the word, never by whether the thing is alive.
What English speakers get wrong here
Three errors show up constantly, and all three are English habits leaking through.
The first is reaching for a neutral pronoun and landing on il by default for every object. La voiture ? Il est petite is wrong twice over — wrong pronoun, and the adjective exposes it. If you cannot recall a noun’s gender, that is a signal to relearn the noun, not to guess the pronoun.
The second is conjugating on as a plural. It means we, so the plural ending feels right. It isn’t. On behaves like il forever.
The third is treating tu as friendly and vous as cold. Vous is not distance, it is default courtesy — the neutral setting, not the frosty one.
