How to Teach “Could” in French – Present Conditional vs. Imperfect – A French Teacher’s Guide
When English-speaking students learn that pouvoir means “can” or “to be able to,” they usually have no trouble with the present tense.
The problem comes when they want to say could.
Should they use the conditional?
Should they use the imperfect?
And what happens when could comes after si?
I teach this by separating the different meanings of could instead of trying to give students one translation. The English word stays the same, but French uses different tenses depending on what the sentence means.
French Conditional and Imperfect Tenses – Could and Would

I start with pouvoir in the present conditional
I first explain that could is often expressed in French using pouvoir in the present conditional.
The conditional is used for hypothetical events or possibilities that aren’t guaranteed to happen.
The forms students need are:
je pourrais
tu pourrais
il/elle/on pourrait
nous pourrions
vous pourriez
ils/elles pourraient
I then give students practical examples:
Je ne pourrais jamais vivre en ville.
I could never live in the city.
Pourrais-tu allumer le four ?
Could you turn on the oven?
Est-ce qu’elle pourrait venir vers 17h00 ?
Could she come around 5:00 pm?
Nous pourrions aller au parc.
We could go to the park.
Pourriez-vous m’aider ?
Could you help me?
Ils pourraient partager les frais.
They could share the costs.
I want students to recognize that these sentences are hypothetical possibilities. They aren’t saying that something actually happened or that someone definitely can do something.
I point out that “could” doesn’t always mean conditional
This is where I tell students to be careful.
It is tempting to learn:
could = pourrais / pourrait / pourrions / pourriez / pourraient
and use the conditional every time they see could in English.
But that’s not how it works.
The tense changes depending on the context.
The first important exception is when could follows si.
I teach “could” after si with the imperfect
I explain that when could follows si in a second conditional sentence, pouvoir must be in the imperfect.
This is a particularly important pattern because students often want to use the conditional after si.
The pattern is:
si + imperfect → conditional
The order of the two clauses can change, but the tense after si does not.
For example:
Je ferais un grand voyage si je pouvais.
I would take a big trip if I could.
Here we have:
je ferais → conditional
si je pouvais → imperfect
We can reverse the clauses:
Si tu pouvais, irais-tu voir ta famille ?
If you could, would you go to see your family?
The pattern is still:
si + imperfect → conditional
I emphasize that it doesn’t matter which clause comes first. What matters is the tense used in each clause.
I give students several examples with pouvoir
Once students understand the basic pattern, I give them examples where pouvoir appears in the imperfect after si.
Ce serait sympa si tu pouvais m’aider.
It would be nice if you could help me.
Nous pourrions venir avec vous si notre chien pouvait nous accompagner.
We could come with you if our dog could accompany us.
Si vous pouviez tout recommencer, qu’est-ce que vous changeriez ?
If you could do it all over again, what would you change?
Ils viendraient s’ils pouvaient.
They would come if they could.
I have students look specifically at the verb after si.
si tu pouvais
si notre chien pouvait
si vous pouviez
s’ils pouvaient
They’re all imperfect.
This gives students a useful rule they can apply when they encounter new examples.
I show students that the clauses can switch places
I want students to see that the position of the clause doesn’t determine the tense.
Compare:
Je ferais un grand voyage si je pouvais.
and:
Si je pouvais, je ferais un grand voyage.
The clauses have switched places, but the verb forms haven’t changed.
The rule remains:
si + imperfect
and the other clause uses the conditional.
This is an important distinction to practice because students sometimes think that the first verb needs to be conditional simply because it comes first.
Then I teach “could” in the past
Next, I introduce another important use of could.
When we’re talking about an ability or possibility in the past, we use pouvoir in the imperfect.
Here, could means that someone was able to do something or wasn’t able to do something in the past.
There isn’t an indication that the ability had a definite beginning and end.
For example:
Je ne pouvais rien voir.
I could not see anything.
Tu pouvais acheter tout ce que tu voulais.
You could buy anything you wanted.
Il ne pouvait pas faire du yoga.
He could not do yoga.
Nous ne pouvions pas bouger.
We could not move.
I point out that these aren’t hypothetical situations. They’re describing an ability or inability in the past.
That’s why we’re using the imperfect rather than the conditional.
I use repeated past situations to reinforce the imperfect
I also give students examples where the past ability was part of an ongoing or repeated situation.
Quand vous aviez vingt ans, vous pouviez sortir tous les soirs.
When you were twenty years old, you could go out every evening.
The imperfect pouviez describes what you were able to do during that period of your life.
I also use:
Elles ne pouvaient pas s’en empêcher.
They could not help themselves.
They could not help it.
Again, pouvaient describes an ability or inability in the past.
I compare the different uses of “could”
Once students have seen all three situations, I put them side by side.
Hypothetical “could”
Use pouvoir in the present conditional:
Je pourrais venir.
I could come.
“Could” after si
Use pouvoir in the imperfect:
Si je pouvais, je viendrais.
If I could, I would come.
“Could” referring to past ability
Use pouvoir in the imperfect:
Je pouvais venir.
I could come / I was able to come.
This comparison is really the heart of the lesson.
The English word is the same:
could
But the French tense depends on the meaning.
I have students identify the situation before conjugating pouvoir
When students practice, I don’t want them to immediately translate the English word could.
Instead, I have them ask themselves what kind of could they’re dealing with.
Is it a hypothetical possibility?
→ Present conditional
Is it could after si?
→ Imperfect
Is it describing an ability or possibility in the past?
→ Imperfect
Only after they’ve identified the situation do they choose the appropriate form of pouvoir.
This helps prevent students from automatically reaching for the conditional every time they see could.
I practice the si clause pattern separately
Because the si + imperfect pattern is so important, I give students some practice where the main goal is simply to recognize the two tenses.
For example:
Si je pouvais, je __________.
Students complete the second clause with the conditional.
Or I reverse it:
Je __________ si je pouvais.
This gives them repeated practice with the pattern:
Si + imperfect, conditional.
I also make sure they see examples where pouvoir isn’t the verb in the other clause:
Si tu pouvais, irais-tu voir ta famille ?
Si vous pouviez tout recommencer, qu’est-ce que vous changeriez ?
That way, students learn the actual conditional pattern rather than thinking that it only applies to pouvoir.
I come back to the meaning of “could”
I finish by bringing students back to the question they should ask themselves whenever they see could.
What does could mean here?
If it expresses a hypothetical possibility, use the present conditional:
Je pourrais…
If it comes after si in a second conditional:
si je pouvais…
If it describes what someone was able to do in the past:
je pouvais…
Once students understand that distinction, they have a much better way of deciding between the conditional and imperfect.

If your students need practice distinguishing pouvoir in the present conditional and imperfect, especially with could in second conditional si clauses and past situations, the resources in this bundle give them an opportunity to work with the different patterns in context.
