We write a quick message to a colleague: “I’m leaving at 2 PM.” The spell checker highlights it in red. We hesitate, we correct, we doubt again. The problem rarely comes from a lack of vocabulary, but from a poorly ingrained reflex regarding the root of the verb partir in the present indicative.
Leaving in the present: the trap of the changing root
Most errors with partir come from a confusion of groups. We treat partir as a second-group verb (like finir), while it belongs to the third group of -ir verbs. The difference is concrete: finir retains its complete root in all persons (I finish, we finish), while partir loses part of its root in the first three.
In the singular, the root is reduced to “par-“: I leave, you leave, he/she leaves. The “t” of partir disappears before the “s” of the ending. This is a remark that Larousse explicitly states. In the plural, the complete root “part-” returns: we leave, you leave, they leave.
This same mechanism is found with other third-group verbs like sortir, sentir, or dormir. Working on the conjugation of the verb partir in the present thus provides a solid reference for this entire family of irregular -ir verbs.
Endings of the verb partir in the present indicative
Rather than an isolated table, here are the forms placed within their logic. We break the verb into two blocks to fix the mechanics.
Singular block: short root + endings -s, -s, -t
I leave, you leave, he/she leaves. We notice that the endings are identical to those of many third-group verbs (I go out, you go out, he goes out). The root loses its final consonant “t” and the endings take over.
Plural block: complete root + endings -ons, -ez, -ent
We leave, you leave, they leave. Here, the root regains its long form. The endings are those of the majority of French verbs in the plural, without exception.
| Person | Root | Ending | Conjugated form |
|---|---|---|---|
| I | par- | -s | I leave |
| you | par- | -s | you leave |
| he/she | par- | -t | he/she leaves |
| we | part- | -ons | we leave |
| you | part- | -ez | you leave |
| they | part- | -ent | they leave |

Concrete method to remember partir without a table in front of you
A table, we consult it, we close it, we forget it. To anchor the conjugation of partir, we can rely on a two-step approach that also works orally.
Step 1: identify the subject and number. If the subject is singular (I, you, he), we cut the root to “par-“. If the subject is plural (we, you, they), we keep “part-“. That’s the only choice to make. The rest follows the standard endings.
Step 2: check by ear with sortir. We mentally conjugate sortir in the same person. If the form of sortir sounds right, that of partir follows the same pattern: I go out / I leave, we go out / we leave, they go out / they leave. This parallel works for every person without exception.
This analogy method is more reliable than mechanical recitation because it creates a network between several third-group verbs. Instead of memorizing a list, we memorize a mechanism.
Frequent confusions with partir in the present
Three situations pose recurring problems, especially in writing.
- Writing “I parti” or “I partie” instead of “I leave”: this is a confusion between the present indicative and the past participle. In the present, the form is always “I leave” with a final -s. “Parti” only appears in the passé composé (I left).
- Writing “he parts” by adding an -s to the third person singular: we mistakenly apply the plural rule of nouns. In the present, the third person takes a -t, not an -s. He leaves, period.
- Confusing partir (third group) with second-group verbs like finir: in the present, finir gives “I finish” with the complete root, while partir gives “I leave” with a truncated root. The simple test: if the present participle does not end in -issant, it is third group (parting, not “partissant”).
Leaving in the present to express a near future
A common usage that is often forgotten: the present of partir can replace the future when the temporal context is clear. “I leave tomorrow at 8 AM” is a perfectly correct sentence to express a future action, without going through the construction “I am going to leave”.
This is a useful point for learners of French as a foreign language, but also for native French speakers who wonder if “we leave next week” is grammatically valid. The answer is yes: the present with future value works with partir as soon as a time complement removes the ambiguity.

The verb partir in the present can be summarized by a single mechanism: short root in the singular, complete root in the plural, standard third-group endings. The parallel with sortir, sentir, or dormir allows checking any form in a few seconds, without reopening a conjugation table.
