When writing a quick message or responding verbally, the verb partir presents a very concrete problem: one hesitates between “je pars” and “je parts,” doubts the “t” in the third person, and sometimes applies a single root “part-” to all persons. This uncertainty stems from a specific mechanism that conjugation tables display without ever explaining: the change of root between the singular and plural.
The trap of the double root par- and part- in the present indicative
The most common mistake with the verb partir in the present tense is to write “je parts” or “tu parts,” keeping the “t” from the root. One applies the endings -s, -s, -t to “part-” as if the root remained the same for all persons. It makes sense, but it’s incorrect.
The actual mechanism works in two stages. In the singular, the root loses its final consonant: “part-” becomes “par-.” Then, the endings -s, -s, -t are added. Result: je par-s, tu par-s, il par-t. The “t” seen in the third person is from the ending, not from the root.
In the plural, the complete root “part-” returns. We add -ons, -ez, -ent: nous part-ons, vous part-ez, ils part-ent. Detailed resources can be found on partir in the present on Liens Vers Emploi that break down this transition form by form.
This double root is not unique to partir. It concerns an entire group of third-group verbs: sortir, dormir, mentir, sentir, servir. The rule is the same: in the singular, the last consonant of the root drops.
Complete conjugation of partir in the present: the six forms to remember
Here are the correct forms, without ambiguity:
| Person | Form | Root used |
|---|---|---|
| je | pars | par- |
| tu | pars | par- |
| il / elle | part | par- |
| nous | partons | part- |
| vous | partez | part- |
| ils / elles | partent | part- |
The column “root used” visually shows the switch. In the singular, we write par- without the t from the root. In the plural, the t reappears because the complete root is retained before the ending.
Method of three pivot forms to memorize partir
Learning all six persons at once is not the most effective method. Recent pedagogical approaches suggest focusing on just three forms: je pars, nous partons, ils partent. These three forms are enough to reconstruct the entire table.
- “Je pars” gives the short root par- and the ending -s, which also applies to “tu pars.”
- “Nous partons” reveals the long root part- and the ending -ons, allowing one to deduce “vous partez” by simple change of ending (-ez).
- “Ils partent” confirms the return of the long root in the plural and the ending -ent, useful for checking consistency with “nous partons.”
With these three reference points, one covers the change of root and the two sets of endings. The rest can be deduced effortlessly. This approach also works for sortir (je sors, nous sortons, ils sortent) or dormir (je dors, nous dormons, ils dorment).
Testing in real situations
One retains a conjugation better by using it in a complete sentence than by reciting a table. A few sentences to repeat or write:
- I leave at eight o’clock, you leave at nine o’clock.
- She leaves without warning, we leave together.
- You leave early, they leave late.
The idea is not to multiply exercises but to anchor the forms in a context similar to what one writes daily. A natural sentence anchors better than an abstract list.
Common mistakes with the verb partir and how to avoid them
Three confusions regularly arise, particularly among learners of French as a foreign language and middle school students.
Writing “je parts” with a t
This is the most widespread mistake. One reasons from the infinitive “partir,” identifies the root “part-,” and sticks the ending -s to it. The result, “je parts,” seems logical. To avoid this, one remembers that the singular of the present cuts the last consonant of the root in this group of verbs.
Confusing the auxiliary in the passé composé
Partir is conjugated with the auxiliary être, not avoir. One says “je suis parti,” never “j’ai parti.” This point does not directly concern the present indicative, but confusion often arises when working with several tenses in parallel. Keeping in mind that partir expresses movement helps choose the right auxiliary.
Mixing partir and partager
Feedback varies on this point, but some learners confuse the forms of partir and similar verbs like partager (first group) or repartir. The test is simple: if the infinitive ends in -ir and belongs to the dormir/sortir/partir group, the double root rule applies. If it is a verb ending in -er, the endings are those of the first group (-e, -es, -e, -ons, -ez, -ent).
Partir in the present and other third-group verbs ending in -ir
The verb partir does not function like finir. This is a point that misleads many French speakers. Finir is part of the second group -ir verbs, with a root that lengthens in the plural by adding -iss- (nous finissons). Partir, on the other hand, belongs to the third group: no -iss-, but a root that loses its final consonant in the singular.
To know if an -ir verb is conjugated like partir or like finir, one looks at the first person plural. If one hears “-issons” (nous finissons, nous choisissons), it is the second group. If one hears simply “-ons” without “-iss-” (nous partons, nous dormons, nous sortons), it is the third group, and the rule of the truncated root in the singular applies.
This distinction between the second and third groups is ultimately the only real choice to make. Once one has identified the group, the conjugation of partir in the present becomes mechanical: short root in the singular, complete root in the plural, standard third-group endings.
