  • Common errors
Two more present-tense families: You already know -er verbs (parler, aimer). French has two more regular present families: verbs whose infinitive ends in -ir (like finir, to finish) and verbs ending in -re (like vendre, to sell). Each has its own set of endings. The single biggest thing to learn: most -ir verbs add a little -iss- in the three plural forms (nous finissons), while -re verbs have no ending at all in the il / elle form (il vend).
un verbe en -ir
an -ir verb (finir, choisir, réfléchir) — most take -iss- in the plural
un verbe en -re
an -re verb (vendre, attendre, répondre, entendre)
le radical
the stem — what's left after you remove -ir or -re (fin-, vend-)
la terminaison
the ending — the part that changes with the person (-is, -ons, -ez…)
finir
to finish — the model -ir verb
vendre
to sell — the model -re verb
Same jobs as -er verbs: These verbs do the same jobs as -er verbs — habits, facts, the here-and-now, near-future plans. Only the endings change. Master finir and vendre as your two models and you can conjugate dozens of high-frequency verbs (choisir, réussir, attendre, répondre, perdre…).
Drop the ending, add the new one: Take the infinitive, remove -ir or -re to find the stem, then add the endings below. For -ir verbs of the finir type, the three plural forms gain an extra -iss- (the part learners forget). For -re verbs, the il / elle / on form takes no ending — just the bare stem (il vend).

-ir « partir »-s · -s · -t · -ons · -ez · -ent (no -iss-)dormir, sortir, partir, sentir, servir
Watch the small « partir » family: Not every -ir verb adds -iss-. A small but very common group — partir, sortir, dormir, sentir, servir — instead drops the last consonant of the stem in the singular: je pars (not « je partis »), tu pars, il part; then nous partons, vous partez, ils partent. Learn these few by heart so you don't force a wrong -iss- onto them.

Same jobs as the present: -ir and -re verbs cover exactly the same uses as the present you already know — the endings are the only difference. Here are the everyday uses, each shown with a high-frequency -ir or -re verb.

Emplois du présent (-ir / -re)

  • Habits & routines — « Je finis mes devoirs après le dîner. » (I finish my homework after dinner.)
  • General facts — « Ce magasin vend des livres d'occasion. » (This shop sells second-hand books.)
  • Actions happening now — « J'attends le bus depuis dix minutes. » (I've been waiting for the bus for ten minutes.)
  • Near-future plans — « Ce week-end, je choisis ma tenue pour la fête. » (This weekend, I'm choosing my outfit for the party.)
  • Reactions & opinions — « Je réfléchis avant de répondre. » (I think before I answer.)
Don't over-think the meaning: A -ir or -re verb in the present means just what you'd expect: « je finis » is simply I finish, « il vend » is he sells. The only challenge is the form — pick the right ending for the person and the rest works like any present verb.
A day told with -ir and -re verbs: Here's a short everyday paragraph built one sentence at a time. Each sentence packs in -ir verbs (finir, choisir, réfléchir), -re verbs (attendre, répondre, entendre) and a couple from the partir family (dormir). Read it once for meaning, then tap Voir la traduction for the English or 🔊 to hear it.

Le présent en -ir et -re en action

Une journée, phrase à phrase

  1. Le matin, je finis mon petit-déjeuner et je choisis des vêtements confortables.
  2. À l'arrêt de bus, j'attends le 12 et je réfléchis à ma journée.
  3. En cours, le professeur pose une question et nous répondons tous ensemble.
  4. Après les cours, mes amis et moi finissons nos devoirs à la bibliothèque.
  5. Le soir, j'entends de la musique, je réfléchis un peu, puis je dors profondément.
Steal this for your routine: Notice how many everyday verbs are -ir / -re: je finis, je choisis, je réfléchis, j'attends, nous répondons, j'entends, je dors. Learn the two endings sets and you can describe a whole day. Swap in your own activities and you have a ready-made paragraph.

The slips to watch for: Three mistakes dominate. Forgetting the -iss- in finir-type plurals (« nous finons » instead of finissons). Adding an ending to the il form of an -re verb (« il vendt » instead of bare il vend). And forcing -iss- onto the partir family (« je finis » is fine, but « je dormis » is wrong — it's je dors). Compare the right version with the typical mistake and the fix becomes obvious.

Correct

  • Nous finissons à midi.
  • Il vend des journaux.
  • Je dors huit heures par nuit.
  • Vous choisissez un dessert.

Erreur fréquente

  • Nous finons à midi.
  • Il vendt des journaux.
  • Je dormis huit heures…
  • Vous choisez un dessert.
Ask: which family is this verb?: Before you conjugate, decide the family. finir type → add -iss- in nous / vous / ils (finissons, choisissez, réussissent). vendre type → no ending on il (il vend, il attend, il répond). partir type → drop the last stem consonant in the singular and use no -iss- (je pars, je dors, je sors).
