The Roadmap to French Conjugation: Verb Groups Explained
3 min read
If a French conjugation table ever felt like a scrambled puzzle, you are not alone. Verbs are not a random pile of words—they are sorted into three groups.
Learning which group a verb belongs to is one of the biggest shortcuts in French: you stop trying to memorize thousands of one-off forms and start applying repeatable patterns.
- How the infinitive ending predicts default conjugation behavior.
- Why Group 2 is not “every -ir verb”—the -issons signature.
- A present-tense snapshot for regular Group 1 and Group 2 verbs.
- A three-step habit: spot the group, prioritize heavy hitters, then apply the pattern.
Why Do Verb Groups Matter?
In French, the infinitive (the dictionary form: “to speak,” “to finish”) almost always ends in one of a few patterns. That ending is your first clue to how the verb will behave in the present and beyond.
Think of it like car models: once you know how a manual transmission works, you can drive almost any manual car. Verb groups are the “transmission” of French grammar—same idea, different paint job.
Group 1: The “-er” Verbs (the Reliable Majority)
Roughly 90% of French verbs are Group 1. If you meet a new verb today (skyper, texto, regional favorites), it is almost certainly -er and regular.
- Ending: -er
- Examples: parler, manger, habiter
- Feel: mostly predictable—one core pattern with a small set of spelling tweaks (e.g. manger → nous mangeons).
- Watch the imposter: aller ends in -er but is not Group 1. It is a highly irregular Group 3 verb wearing a Group 1 costume.

Group 2: The “-ir” Verbs (the “-iss-” Group)
Group 2 verbs are regular, but not every -ir verb belongs here. True Group 2 verbs share a clear plural “signature.”
- Ending: -ir (in the infinitive)
- Examples: finir, choisir, réussir
- Signature: nous ends in -issons (nous finissons). If you do not get that -iss- stretch in the plural, you are probably looking at a Group 3 -ir verb such as partir or dormir.
Group 3: The “Wild West” (-re, -oir, and Irregular -ir)
Group 3 is the everything else bucket. It holds some of the most common verbs (être, avoir, faire) and many of the least pattern-friendly ones. There is no single magic rule—you learn families and models instead of one blanket ending.
- Typical endings: -re, -oir, plus irregular -ir verbs (e.g. partir, sortir, dormir).
- Examples: prendre, vouloir, voir, partir.
- Feel: high effort, high reward—these verbs dominate real conversation, so time spent here pays off quickly.
Summary Table: Present Tense “Identity Tags” (Regular Verbs)
For regular Group 1 and Group 2 verbs in the present, you drop the infinitive ending and add the endings below. (Irregular Group 3 verbs follow their own families.)
| Subject | Group 1 (-er) | Group 2 (-ir) |
|---|---|---|
| Je | -e | -is |
| Tu | -es | -is |
| Il / elle / on | -e | -it |
| Nous | -ons | -issons |
| Vous | -ez | -issez |
| Ils / elles | -ent | -issent |
How to Master the Groups
Do not try to memorize the dictionary in alphabetical order. Use a small daily loop (see our 10-minute conjugation routine) and three habits:
- Spot the ending first: label a new verb as Group 1, Group 2, or Group 3 before you conjugate.
- Learn the “Big Ten” early: Group 3 heavyweights (être, avoir, faire, aller, etc.) anchor almost every tense—prioritize them.
- Default to the pattern: for a new -er verb, assume regular Group 1 until you meet a proven exception; for -ir, check for -issons before you assume Group 2.
Ready to practice? You now have the map—next is walking it. Use present-tense drills for Group 1 muscle memory, browse conjugation models when Group 3 splinters, and keep high-frequency verbs in rotation.
