How to Teach “Should Have,” “Could Have,” and “Would Have” in French – Past Conditional – A French Teacher’s Guide
The French past conditional is the tense students need when they want to express should have, could have, or would have.
I find that the easiest way to teach it is to connect it directly to something students already know: the passé composé with avoir and être as helping verbs.
The basic structure is very similar. The main difference is that instead of putting avoir or être in the present tense, we put the helping verb in the present conditional.
Once students understand that connection, the past conditional becomes much less intimidating.

I start with “should have,” “could have,” and “would have”
I begin with the English expressions because they give students an immediate reason for learning this tense.
When we want to say that someone should have done something, could have done something, or would have done something, French uses the past conditional.
I introduce the three expressions together:
should have
could have
would have
Then I tell students that they are going to see a pattern that connects all three.
I don’t start by asking them to memorize a complicated conjugation. Instead, I first remind them of how the passé composé works.
I connect the past conditional to the passé composé
This is the most important connection I make in this lesson.
I ask students what they already know about forming the passé composé.
They already know that we need:
helping verb + past participle
They also know that the helping verb can be avoir or être, depending on the verb.
I explain that the past conditional works the same way.
The rules for choosing between avoir and être are the same as they are in the passé composé.
The difference is that the helping verb is no longer in the present tense.
It goes into the present conditional.
So the basic idea is:
present conditional of avoir or être + past participle
That is the key to forming the French past conditional.
I review the present conditional of avoir and être
Before students start forming past conditional sentences, I make sure they know the present conditional forms of the two helping verbs.
For avoir:
j’aurais
tu aurais
il/elle/on aurait
nous aurions
vous auriez
ils/elles auraient
For être:
je serais
tu serais
il/elle/on serait
nous serions
vous seriez
ils/elles seraient
I want students to know these forms well because they are going to use them constantly in the past conditional.
Your choice of helping verb hasn’t changed.
You’re simply changing the tense of that helping verb.
I show students how similar this is to the passé composé
I find it helpful to put the two structures next to each other.
With the passé composé:
avoir or être in the present + past participle
With the past conditional:
avoir or être in the present conditional + past participle
For example, the important change isn’t the past participle.
The change is the helping verb.
This is why I tell students that if they already understand the passé composé, forming the past conditional should feel much more familiar. The lesson guide specifically emphasizes reviewing the passé composé rules and knowing the present conditional forms of avoir and être.
I explain “would have”
I then focus specifically on would have.
One thing I point out to students is that the English word would doesn’t exist by itself in French in the same way.
When you want to say that you would have done something, the main verb is put into the past conditional.
So students need to think in terms of the entire expression:
would have + past participle
rather than looking for a single French word that means “would.”
The French verb itself carries the conditional meaning through the helping verb.
I remind students that avoir and être still work the same way
This is where students sometimes want to start treating the past conditional as an entirely new system.
I remind them that it isn’t.
If a verb takes avoir in the passé composé, it takes avoir in the past conditional.
If a verb takes être in the passé composé, it takes être in the past conditional.
The helping verb simply changes from the present to the present conditional.
This is why I make sure students are comfortable with their passé composé rules before expecting them to produce the past conditional independently.
I bring in devoir for “should have”
Next I focus on devoir, which is particularly important for expressing should have.
Students already know devoir as the verb meaning “must” or “to have to.”
Now I show them how it works in the past conditional.
The important thing is that devoir itself is put into the past conditional when we want to express should have.
This gives students a very useful connection:
devoir + past conditional meaning → should have
I have students practice identifying the helping verb and the past participle rather than trying to memorize the entire sentence as one unit.
I bring in pouvoir for “could have”
I do the same thing with pouvoir.
Students have already learned that pouvoir means “can” or “to be able to,” and they have seen it in the present conditional for could.
Now they can take that idea one step further.
When we want to express could have, we use pouvoir in the past conditional.
This makes a nice connection to the lesson I teach on could in the present conditional versus imperfect.
Students can see that they’re not learning an unrelated new verb. They’re learning how to move pouvoir into another tense.
I have students focus on the helping verb
At this point, I have students practice identifying the helping verb before worrying about the rest of the sentence.
I ask:
Is this verb formed with avoir or être?
Once they know that, they can put the appropriate helping verb into the present conditional.
Then they add the past participle.
This reinforces the connection with the passé composé and keeps the formation from feeling like an entirely new concept.

I review the passé composé rules before moving on
I don’t want students to forget that the past conditional depends on what they already know about the passé composé.
I review the rules they need:
- Which verbs use avoir
- Which verbs use être
- How to form the past participle
- Agreement when être is used
The past conditional doesn’t replace those rules.
It builds on them.
The lesson guide specifically emphasizes that the same rules for choosing avoir versus être apply when forming the past conditional.
I have students practice the three English expressions together
Once students understand the formation, I bring should have, could have, and would have back together.
I have students identify which English expression they’re trying to express and then determine the French structure they need.
This keeps the lesson connected to the reason we’re learning the tense in the first place.
Rather than giving students a page of isolated conjugations, I want them working with meaningful sentences that require them to choose and form the past conditional.

I remind students that the past conditional is not completely new
This is probably the most important message I give students during this lesson.
They already know two major pieces of the puzzle:
The passé composé gives them the helping-verb rules and past participles.
The present conditional gives them the conditional forms of avoir and être.
Put those two things together, and they have the French past conditional.
The lesson guide’s final reminder is exactly the preparation I want students to have: review the passé composé rules and know the present conditional conjugations of avoir and être well.
