Subjonctif present - irregular pouvoir

In French, we use the indicative for facts.

'I can speak French' is a fact.

But the subjunctive is for the heart.

It is for dreams, doubts, and needs.

It lives in the land of 'maybe'.

When you use pouvoir, you express ability.

In the subjunctive, that ability is clouded.

Maybe it is a wish you have.

Maybe someone is forcing you to act.

It always follows the magic word que.

Without que, there is usually no subjunctive.

Think of it like a grammar bridge.

You cross the bridge to enter a mood.

It is where feelings rule over cold facts.

Yes, even native speakers pause sometimes.

It is okay to take your time.

1. 1Most French verbs follow a strict recipe.
2. 2You take the 'they' form and cut.
3. 3Then you add some standard endings.
4. 4But pouvoir decided to be different.
5. 5It uses a totally unique root.
6. 6You must memorize this special stem: puiss-.
7. 7It sounds a bit like a 'shhh' sound.
8. 8Here is how you build it:
9. 9Start with the root puiss-.
10. 10Add the ending -e for je.
11. 11Add -es for the tu form.
12. 12Add -e for il, elle, or on.
13. 13Use -ions for the nous form.
14. 14Use -iez for the vous form.
15. 15Add -ent for the ils or elles form.
16. 16It looks like this in full:
17. 17que je puisse
18. 18que tu puisses
19. 19qu'il puisse
20. 20que nous puissions
21. 21que vous puissiez
22. 22qu'ils puissent
23. 23Notice the 'i' in the nous and vous.
24. 24It is like a little secret code.
25. 25You've got this pattern down now.

The subjunctive pops up in specific places.

One huge trigger is the phrase il faut que.

This means 'it is necessary that'.

Imagine you are at a job interview.

You say, 'It is necessary I can work'.

In French: Il faut que je puisse travailler.

You also use it for strong wishes.

Maybe you want a friend to succeed.

'I want you to be able to come'.

That uses the subjunctive of pouvoir.

Use it when you feel doubt too.

'I doubt he can finish the race'.

It is perfect for ordering food politely.

'I wish I could have some cake'.

Well, that is more for fancy requests.

It helps you sound very natural.

Think of it as a social tool.

It makes your French feel more fluid.

It shows you understand subtle emotions.

Grammar is just a way to connect.

Do not use it for simple facts.

'I can swim' is just Je peux nager.

No que, no subjunctive mood needed.

Also, do not use it with certainty.

Words like je sais que love the indicative.

'I know he can do it'.

This uses peut, not the puisse form.

Another rule: check the subjects.

Are the subjects the same person?

'I want to be able to go'.

In French, we use the infinitive here.

Je veux pouvoir partir.

We only use puisse for different people.

'I want YOU to be able to go'.

Now the bridge is open for us.

Keep it simple and avoid overthinking it.

Many people try to use the indicative.

They say Il faut que je peux.

This sounds very wrong to French ears.

It is like saying 'I goes' in English.

Remember: que is your warning sign.

Another mistake is forgetting the root.

Some try to use pouv- or peuv-.

Nope, only puiss- works in the subjunctive.

Also, watch out for the nous form.

People often forget that extra 'i'.

Que nous puissions is the right way.

Que nous pussions is a different thing.

Don't let the 's' sounds scare you.

Just hiss a little and move on.

Everyone makes mistakes when learning this.

Even teachers slip up on occasion.

Just laugh and try it again later.

Compare je peux and que je puisse.

The first is a hard fact.

The second is a soft possibility.

Think of it like a light switch.

Peux is the 'on' position for reality.

Puisse is the 'dimmer' for feelings.

Another contrast is with the verb vouloir.

Je veux (I want) often triggers puisse.

But je pense (I think) usually does not.

Unless you say 'I do NOT think'.

Negatives can change the grammar rules.

It is like a game of chess.

You must look at the whole board.

Is there a que? Is there doubt?

If yes, reach for that puiss- root.

It is your best friend in uncertainty.
