Comprendre is the verb to understand — the workhorse of expressing comprehension, agreement, and intellectual grasp in everyday French. It is also, more literally, the verb to comprise or to include — a dual sense traceable to its Latin source (com-prehendere, "to grasp together"). Both readings are alive in modern French: je comprends ton point de vue (I understand your perspective) versus le menu comprend une entrée, un plat et un dessert (the menu includes a starter, a main, and a dessert).
Comprendre is one of the most-used verbs in French — from polite acknowledgment (je comprends) to checking whether someone follows you (tu comprends ?) to academic register (il faut comprendre que...). It belongs to the prendre family, sharing the conjugation of prendre, apprendre, surprendre, entreprendre, and reprendre. The high-frequency idiom y compris (including) is a fossilized form of its past participle compris: tout est inclus, taxes comprises (everything is included, taxes included).
The simple tenses
Comprendre is a member of the prendre family. The conjugation is identical to prendre — same three-stem present, same compris past participle, same split-stem subjunctive.
Présent de l'indicatif
Three-stem alternation: nasal /ɑ̃/ in the singular, schwa + single n in 1pl/2pl, denasalized /ɛn/ with double n in 3pl.
| Person | Form | Pronunciation |
|---|---|---|
| je | comprends | /kɔ̃pʁɑ̃/ |
| tu | comprends | /kɔ̃pʁɑ̃/ |
| il / elle / on | comprend | /kɔ̃pʁɑ̃/ |
| nous | comprenons | /kɔ̃pʁənɔ̃/ |
| vous | comprenez | /kɔ̃pʁəne/ |
| ils / elles | comprennent | /kɔ̃pʁɛn/ |
The 3pl comprennent /kɔ̃pʁɛn/ has a denasalized vowel: the double n signals /ɛn/ instead of nasal /ɑ̃/. Same pattern as prennent, apprennent, surprennent.
Je ne comprends pas ce que tu veux dire — tu peux préciser ?
I don't understand what you mean — can you be more specific?
Vous comprenez le français ? — Oui, mais parlez lentement, s'il vous plaît.
Do you understand French? — Yes, but please speak slowly.
Les enfants ne comprennent pas toujours pourquoi on dit non.
Children don't always understand why we say no.
Imparfait
Built on the plural stem compren- with regular imparfait endings.
| Person | Form |
|---|---|

| nous | comprenions |
| vous | compreniez |
| ils / elles | comprenaient |
Quand j'avais cinq ans, je ne comprenais pas pourquoi mes parents pleuraient en regardant les infos.
When I was five, I didn't understand why my parents would cry watching the news.

Futur simple
Stem comprendr- with regular futur endings.
| Person | Form |

| nous | comprendrons |
| vous | comprendrez |
| ils / elles | comprendront |
Tu comprendras quand tu seras plus grand.

| Person | Form |
|---|---|
| je | comprendrais |
| tu | comprendrais |
| il / elle / on | comprendrait |
| nous | comprendrions |
| vous | comprendriez |
| ils / elles | comprendraient |
The conditional is heavily used in polite-tentative comprehension: je comprendrais que tu veuilles partir (I'd understand if you wanted to leave).
Je comprendrais que tu sois fâché — j'aurais réagi pareil.
I'd understand if you were angry — I would have reacted the same way.
Personne ne comprendrait une telle décision.
No one would understand such a decision.
Subjonctif présent
Two stems: comprenn- (singular and 3pl) and compren- (1pl, 2pl).

|---|---|
| (que) je | comprenne |
| (que) tu | comprennes |
| (qu')il / elle / on | comprenne |
| (que) nous | comprenions |
| (que) vous | compreniez |
| (qu')ils / elles | comprennent |
The 1pl/2pl forms are spelled identically to the imparfait — context decides.
Il faut que tu comprennes : on ne peut plus continuer comme ça.
You need to understand: we can't go on like this.
Je doute qu'il comprenne vraiment l'enjeu.
I doubt he really understands what's at stake.
Impératif
| Person | Form |
|---|---|
| (tu) | comprends |
| (nous) | comprenons |
| (vous) | comprenez |
The imperative of comprendre most often appears in polite or insistent appeals: comprends-moi bien (understand me well, get me right), comprenez bien (be sure to understand).
Comprends-moi bien : je ne te juge pas, je m'inquiète.
Don't get me wrong: I'm not judging you, I'm worried.
Comprenez bien que cette décision est définitive.
Be quite clear that this decision is final. (formal)
Participles and gérondif
- Participe passé: compris (agrees with preceding direct object when avoir is auxiliary; also used adjectivally in y compris)
- Participe présent: comprenant
- Gérondif: en comprenant
C'est en lisant et en relisant le texte que j'ai fini par le comprendre.
It's by reading and re-reading the text that I finally came to understand it.
The participle compris takes feminine comprise, plural compris / comprises. In adjectival uses (y compris, taxes comprises), the agreement is variable depending on position — see the y compris section below.
The compound tenses
Comprendre uses avoir as its auxiliary throughout.
Passé composé
avoir (présent) + compris
| Person | Form | Translation |
|---|---|---|
| j' | ai compris | I understood / I have understood |
| tu | as compris | you understood |
| il / elle / on | a compris | he/she/we understood |
| nous | avons compris | we understood |
| vous | avez compris | you understood |
| ils / elles | ont compris | they understood |
J'ai enfin compris pourquoi il était si distant — il traversait une période difficile.
I finally understood why he was so distant — he was going through a hard time.
Tu as compris la consigne ? — Oui, c'est clair.
Did you understand the instructions? — Yes, it's clear.
The passé composé j'ai compris often functions as an aspectual marker: it pinpoints the moment of grasping (the realization), as opposed to the imparfait je comprenais which describes ongoing comprehension as a state. This contrast is the same logic as connaître and savoir in compound tenses.
Plus-que-parfait
avoir (imparfait) + compris
J'avais compris ses intentions bien avant qu'il ne parle.
I had figured out his intentions long before he spoke.
Futur antérieur
avoir (futur) + compris
Quand tu auras compris ça, tu comprendras tout le reste.
Once you've understood that, you'll understand everything else.
Conditionnel passé
avoir (conditionnel) + compris
Si tu avais expliqué autrement, j'aurais compris du premier coup.
If you'd explained it differently, I'd have understood first time.
The semantic core: understand vs comprise
Comprendre is etymologically transparent — Latin com-prehendere "to grasp together" — and both of its modern senses preserve this core image.
Sense 1: To understand
The default reading: mental grasp of meaning, reasons, language, situations, people.
Je comprends ce que tu ressens, c'est légitime.
I understand what you're feeling, it's legitimate.
Il ne comprend rien aux mathématiques.
He doesn't understand a thing about math.
On comprend mieux quand on dort assez.
You understand better when you've slept enough.
The construction comprendre quelque chose à + noun is an idiom usually in the negative — je n'y comprends rien (I don't get it at all).
Franchement, je n'y comprends rien à cette histoire.
Honestly, I can't make heads or tails of this story.
Sense 2: To comprise / include
Used with abstract collections, contents, or compositions. The subject is what contains, the object is what's contained.
Le menu comprend une entrée, un plat et un dessert.
The menu includes a starter, a main course, and a dessert.
Le prix comprend les taxes et le service.
The price includes taxes and service.
Cette région comprend cinq départements.
This region comprises five departments.
L'abonnement comprend l'accès illimité aux articles et aux podcasts.
The subscription includes unlimited access to articles and podcasts.
This sense is particularly common in administrative, commercial, and geographic descriptions. It is closer to English comprise, include, consist of than to understand.
Comprendre que — and the mood it triggers
When comprendre is followed by a que-clause, the mood of the verb that follows (indicative or subjunctive) depends on what comprendre means in that context. This is one of the genuinely subtle points about the verb.
Comprendre que + indicative — to realize that
When comprendre que introduces a fact you've grasped, the dependent verb stays indicative.
J'ai compris qu'il ne reviendrait pas.
I realized he wouldn't come back.
On comprend que la situation est délicate.
We can see that the situation is delicate.
Elle a compris que tu mentais.
She figured out you were lying.
Comprendre que + subjunctive — to sympathize with
When comprendre que means "to find acceptable" or "to sympathize with" someone's behavior, the dependent verb takes the subjunctive.
Je comprends que tu sois fatigué — repose-toi.
I understand that you're tired — get some rest. (subjunctive: empathetic understanding)
On comprend que vous soyez en colère, mais essayons de discuter calmement.
We understand that you're angry, but let's try to talk calmly.
Je comprends qu'elle ait voulu partir, après tout ce qu'on lui a fait.
I understand that she wanted to leave, after everything we did to her.
The contrast is real and meaningful for native speakers:
| Form | Reading |
|---|---|
| Je comprends qu'il *est fatigué* (indicative) | I see / realize he is tired (factual recognition) |
| Je comprends qu'il *soit fatigué* (subjunctive) | I understand his being tired / I sympathize with his being tired (empathetic acceptance) |
If a learner masters this distinction — even just at recognition level — French speakers will notice. It is one of the textbook cases where the indicative/subjunctive choice carries semantic weight.
Y compris — including (fossilized form)
Y compris is the standard French expression for including. It is a frozen form of the past participle compris.
Tout est inclus dans le prix, y compris le petit-déjeuner.
Everything is included in the price, including breakfast.
Tous les magasins seront fermés, y compris les pharmacies.
All shops will be closed, including pharmacies.
Agreement
When y compris precedes the noun, it is invariable:
Y compris les enfants, tout le monde a apprécié le spectacle.
Including the children, everyone enjoyed the show.
When compris follows the noun (typically without y), it agrees in gender and number:
Le forfait coûte 50 euros, taxes comprises.
The package costs 50 euros, taxes included.
The fixed phrase taxes comprises / charges comprises is everywhere in French commercial writing — restaurant menus, rental ads, hotel quotes.
Ça comprend — that includes (informal lookup)
A common informal use: when asking what something includes.
Le forfait à trente euros, ça comprend quoi exactement ?
The 30-euro package, what does that include exactly?
Comparison with English
Three friction points for English speakers:
Two senses in one verb. English splits understand and comprise / include. French uses comprendre for both — context disambiguates: a person grasps; an abstract collection (menu, price, region) contains.
The mood-switching que clause. English I understand that you're tired is ambiguous between cognitive and empathetic readings. French splits these via indicative/subjunctive — je comprends qu'il est fatigué (cognitive) vs je comprends qu'il soit fatigué (empathetic).
Y compris is a fixed expression, not productive. English including is a productive present participle. French y compris is fossilized — *y comprenant is wrong. Treat it as a single lexical item.
Common Mistakes
Mistake 1: Subjunctive after every comprendre que.
❌ J'ai compris qu'il ne vienne pas.
Wrong — when comprendre que means 'realize that' (factual), the indicative is required. Subjunctive only with the empathetic reading.
✅ J'ai compris qu'il ne venait pas.
I realized he wasn't coming.
Mistake 2: Indicative after the empathetic comprendre que.
❌ Je comprends que tu es fâché — c'est normal.
If 'I understand' means 'I sympathize / I find it acceptable,' use the subjunctive: que tu sois fâché.
✅ Je comprends que tu sois fâché — c'est normal.
I understand that you're angry — that's normal.
Mistake 3: Confusing comprendre and apprendre for hearing news.
❌ Je comprends que tu déménages à Lyon.
If you mean 'I heard / found out you're moving,' use apprendre, not comprendre. Comprendre is for grasping meaning, not receiving information.
✅ J'ai appris que tu déménages à Lyon.
I heard you're moving to Lyon.
Mistake 4: Using comprendre with de instead of direct object.
❌ Je comprends de ce qu'il dit.
Wrong — comprendre takes a direct object, no preposition. The construction with de doesn't exist.
✅ Je comprends ce qu'il dit.
I understand what he's saying.
Mistake 5: Treating y compris like a verb form.
❌ Tout y comprenant les taxes.
Wrong — y compris is a fixed expression, not a productive participle. It never inflects.
✅ Tout, y compris les taxes.
Everything, including taxes.
Key takeaways
Comprendre covers two senses inherited from Latin com-prehendere: to understand (mental grasp) and to comprise / include (containment). The subject signals which: a person grasps; a menu, price, or collection contains.
The conjugation is identical to prendre: three-stem present (comprend- / compren- / comprenn-), compris past participle, comprendr- in the futur and conditionnel, split-stem subjunctive. Compound tenses use avoir.
The subtlest point is comprendre que: indicative when it means "realize / grasp that," subjunctive when it means "sympathize with / find acceptable that." This split carries real semantic weight. The fossilized form y compris (including) and its variant ... compris(es) (after a noun, with agreement) are everywhere in French commercial and administrative writing.
