The imparfait and the conditionnel présent share a set of endings — -ais, -ais, -ait, -ions, -iez, -aient — and to a beginner's ear they sound nearly identical. They are not. They differ in stem (the imparfait builds on the present-tense nous-stem; the conditionnel builds on the future stem with its characteristic -r-), and in careful speech they also differ in the vowel of the -rai/-rais ending in the first-person singular. This page teaches you to hear and produce that difference.
Why does it matter? Because the two tenses do completely different jobs. Je parlais (imparfait) means "I was speaking" — a description of past activity. Je parlerais (conditionnel) means "I would speak" — a hypothetical, a polite request, a future-in-past. Mishearing one for the other in a conversation can flip a story about yesterday into a hypothetical about tomorrow, or turn a polite request into a description. For listening comprehension at B1 and above, this is the single highest-leverage contrast you can drill.
Two parts to the distinction
The contrast lives in two places: the stem (which is the major and reliable cue) and, separately, the first-person singular ending vowel (which is a finer cue, alive in careful speech but disappearing in casual speech).
Cue 1: the stem — listen for /ʁ/
The imparfait stem is the present-tense nous-form minus -ons. So parler → nous parlons → imparfait stem parl-: je parlais /ʒə paʁ.lɛ/.
The conditionnel stem is identical to the futur simple stem, which always contains an -r- (or -rr-). So parler → futur stem parler- → conditionnel je parlerais /ʒə paʁ.lə.ʁɛ/.
The structural difference is the extra /ʁ/ (often with a schwa /ə/ before it) inserted between the verb root and the ending. If you hear an /ʁ/ before the -ais ending, you are hearing the conditionnel. If you do not, you are hearing the imparfait.
Je parlais à mon frère quand tu es arrivé.
I was talking to my brother when you arrived.
Je parlerais à mon frère, mais il ne répond plus à mes messages.
I would talk to my brother, but he doesn't reply to my messages anymore.
The first sentence has /paʁ.lɛ/ — two syllables, no /ʁ/ between parl- and -ais. The second has /paʁ.lə.ʁɛ/ — three syllables, with a clear /ʁ/ between parl- and -ais. In rapid speech the schwa often drops, giving /paʁ.lʁɛ/ — still three "beats," still with the extra /ʁ/.
Cue 2: the vowel — /e/ vs /ɛ/ in 1sg
In educated French, the first-person singular endings of the futur simple and the conditionnel présent are distinguished by vowel quality:
- Futur 1sg -rai is pronounced /e/ (closed, like the é in café).
- Conditionnel 1sg -rais is pronounced /ɛ/ (open, like the è in père).
So je serai /ʒə.s(ə).ʁe/ ("I will be") and je serais /ʒə.s(ə).ʁɛ/ ("I would be") form a minimal pair distinguished only by /e/ vs /ɛ/. The spelling helpfully signals the difference: futur 1sg ends in -rai (no s), conditionnel 1sg ends in -rais (with a silent s).
Note that this /e/ vs /ɛ/ contrast applies only in the 1sg distinction between futur and conditionnel. The contrast between conditionnel and imparfait — both of which have the -ais ending — relies entirely on the stem cue (the /ʁ/). All persons of the conditionnel use the open /ɛ/.
| Form | Spelling | Pronunciation | Meaning |
|---|---|---|---|
| Futur 1sg | je serai | /ʒə s(ə).ʁe/ | I will be |
| Conditionnel 1sg | je serais | /ʒə s(ə).ʁɛ/ | I would be |
| Imparfait 1sg | j'étais | /ʒe.tɛ/ | I was |
A modern caveat: many younger speakers, especially in the Paris region, are merging /e/ and /ɛ/ in unstressed final position. For them, je serai and je serais sound identical, both somewhere between /e/ and /ɛ/. In careful, formal, or northern non-Parisian speech, the distinction is preserved. In casual fast speech you cannot rely on it. So treat /e/ vs /ɛ/ as a useful but secondary cue, and rely primarily on the /ʁ/-stem cue to tell conditionnel from imparfait.
The full minimal-pair drill
Practice these aloud. Record yourself if you can — your ear is the best judge.
| Imparfait | Conditionnel | Key difference |
|---|---|---|
| je parlais /paʁ.lɛ/ | je parlerais /paʁ.lə.ʁɛ/ | extra /ʁ/ + schwa |
| tu finissais /fi.ni.sɛ/ | tu finirais /fi.ni.ʁɛ/ | -iss- vs -r- |
| il vendait /vɑ̃.dɛ/ | il vendrait /vɑ̃.dʁɛ/ | -d- vs -dr- |
| nous avions /a.vjɔ̃/ | nous aurions /o.ʁjɔ̃/ | different stems entirely |
| vous étiez /e.tje/ | vous seriez /sə.ʁje/ | different stems entirely |
| ils faisaient /fə.zɛ/ | ils feraient /fə.ʁɛ/ | -s- vs -r- |
Notice the irregular verbs (être, avoir, faire): for these, the imparfait and conditionnel stems are visibly different, not just one extra /ʁ/. J'étais (imparfait) and je serais (conditionnel) share no consonants at all — once you learn that être's conditionnel/futur stem is ser-, you cannot mishear them. The same is true of j'avais /a.vɛ/ vs j'aurais /o.ʁɛ/, and je faisais /fə.zɛ/ vs je ferais /fə.ʁɛ/.
For regular verbs, the difference is more subtle and worth drilling. Je parlais /paʁ.lɛ/ and je parlerais /paʁ.lə.ʁɛ/ differ only in the inserted /ʁ/ syllable, which a tired or distracted listener can miss.
Quand j'étais petit, je jouais dans le jardin tous les jours.
When I was little, I played in the garden every day.
Si j'avais le temps, je jouerais dans le jardin avec les enfants.
If I had time, I would play in the garden with the kids.
Tu disais quoi ? Je n'ai pas entendu.
What were you saying? I didn't hear.
Tu dirais quoi à ta place ? Honnêtement, je ne sais pas.
What would you say in her place? Honestly, I don't know.
In each pair, the imparfait and conditionnel are doing different communicative jobs. The first describes; the second hypothesizes. Once your ear locks onto the /ʁ/, you can hear which one the speaker meant.
Spelling: the s that matters even though it is silent
In writing, the futur 1sg and conditionnel 1sg are distinguished by a single letter. That letter is silent in pronunciation, but it is the diagnostic if you have any doubt:
- Futur 1sg ends in -rai: je parlerai, je serai, j'aurai, je ferai.
- Conditionnel 1sg ends in -rais: je parlerais, je serais, j'aurais, je ferais.
Memorize the s. When you write, the difference between "I will speak to him" and "I would speak to him" is one letter — and that letter is the difference between a commitment and a hypothesis.
A note on -er verbs and the schwa
Regular -er verbs in the conditionnel insert a schwa /ə/ between the root and the -r-. So parler → conditionnel stem parler- → je parlerais /paʁ.lə.ʁɛ/. In careful speech the schwa is fully pronounced, giving three syllables. In fast casual speech the schwa drops:
J'aimerais bien venir avec vous, mais je travaille demain.
I'd love to come with you, but I'm working tomorrow.
That aimerais in fast speech becomes /ɛm.ʁɛ/ (two syllables), while in careful speech it stays /ɛ.mə.ʁɛ/ (three syllables). The /ʁ/ is the cue that survives in both registers; the schwa is what comes and goes. Train your ear to notice the /ʁ/ even when the schwa is dropped.
Beyond the 1sg: the rest of the paradigm
The /e/ vs /ɛ/ vowel cue applies only to the 1sg of futur and conditionnel. For the other persons, both tenses share the same final vowel — what changes is everything else:
| Person | Futur | Conditionnel |
|---|---|---|
| 1sg | je parlerai /e/ | je parlerais /ɛ/ |
| 2sg | tu parleras /a/ | tu parlerais /ɛ/ |
| 3sg | il parlera /a/ | il parlerait /ɛ/ |
| 1pl | nous parlerons /ɔ̃/ | nous parlerions /jɔ̃/ |
| 2pl | vous parlerez /e/ | vous parleriez /je/ |
| 3pl | ils parleront /ɔ̃/ | ils parleraient /ɛ/ |
So in 2sg, 3sg, 3pl, the difference between futur and conditionnel is /a/ or /ɔ̃/ vs /ɛ/ — much more salient than 1sg. The difficulty is concentrated in 1sg, and that is where you should focus your listening practice.
Common Mistakes
❌ Quand j'étais petit, je parlerais avec mon chien.
Wrong — using conditionnel where the meaning is past habit
✅ Quand j'étais petit, je parlais avec mon chien.
When I was little, I used to talk to my dog.
❌ Si j'avais le temps, je voyageais en Italie.
Wrong — using imparfait in the apodosis of a hypothetical
✅ Si j'avais le temps, je voyagerais en Italie.
If I had time, I would travel to Italy.
❌ Hier soir, je serais fatigué.
Wrong — conditionnel where past description is meant
✅ Hier soir, j'étais fatigué.
Last night, I was tired.
❌ J'aimais un café, s'il vous plaît.
Wrong — imparfait used as a polite request
✅ J'aimerais un café, s'il vous plaît.
I'd like a coffee, please.
❌ Je pensais que tu voulais aller au cinéma demain.
Acceptable as past description, but for future-in-past use conditionnel
✅ Je pensais que tu voudrais aller au cinéma demain.
I thought you'd want to go to the cinema tomorrow.
The first three errors come from confusing the two tenses' meanings; the fourth is a classic English-speaker error (using imparfait for politeness because the schwa-then-/ʁ/ in aimerais is hard to hear and produce). The fifth shows a subtle point: when reporting past thoughts about a future event, the conditionnel is the correct form (the future-in-past).
Key takeaways
- The two tenses share the endings -ais/-ais/-ait/-ions/-iez/-aient — the difference lives in the stem.
- The conditionnel always has a /ʁ/ in its stem (the same /ʁ/ that marks the futur). The imparfait does not.
- In 1sg, the futur ends in /e/ (-rai) and the conditionnel ends in /ɛ/ (-rais) — a vowel-quality contrast preserved in careful speech but increasingly merged in casual Parisian speech.
- For irregular verbs (être, avoir, faire, aller, venir), the imparfait and conditionnel stems are visibly different, not just one /ʁ/ apart — these are easier to distinguish.
- For regular -er verbs, the contrast is subtle: parlais /paʁ.lɛ/ vs parlerais /paʁ.lə.ʁɛ/. Drill these as minimal pairs.
- The silent s in the conditionnel 1sg ending (-rais) is your visual cue when reading; in writing, omitting it changes the meaning of the sentence.
