Peut vs Peu vs Peux in French
Peut, peu, and peux sound alike but mean different things in French. See how to tell them apart with examples and a quick decision rule.
Three spellings, one sound: peu, peut, and peux are the homophone triple that fills French forums with corrections. Your ear can't help you - only grammar can - and the fix takes ten seconds once you know which word does which job.
The decision rule
Try replacing with pouvait: if the sentence survives, it's the verb - peux after je/tu, peut after il/elle/on. If it doesn't, write peu.
Core Difference
Peut and peux are conjugations of pouvoir tied to grammatical subject. Peu is an adverb of quantity with no connection to the verb pouvoir.
Use Peut When
Use peut with il, elle, or on.
Il peut venir demain.
He can come tomorrow.
Use Peux (and Peu) When
Use peux with je or tu. Use peu, unrelated to pouvoir, to mean little or few.
Je peux t'aider.
I can help you.
Tu peux essayer.
You can try.
Side-by-Side Examples
Comparing all three side by side makes the distinction concrete.
Elle peut nager.
She can swim.
peut, subject elle
Il y a peu de temps.
There is little time.
peu, quantity word, unrelated to pouvoir
Edge Cases
"Peu" combines with "un" to form "un peu" (a little), which is nearly the opposite in feel from "peu" alone (very little, hardly any).
J'ai un peu d'argent.
I have a little money.
a modest but real amount
J'ai peu d'argent.
I have little money.
emphasizes scarcity
Common Mistakes
Because all three words sound alike, learners often write "peu" when they mean "peut" or "peux," especially when typing quickly.
Il ne peu pas venir.
(Incorrect) He can't come.
Wrong spelling - should be peut.
Il ne peut pas venir.
He can't come.
Right.
Quick Test
Which is correct: "Je ___ venir ce soir" - peux or peut? Answer: peux, because the subject is je.

Where learners go wrong
Autocorrect can't rescue you here because all three words are real and frequent. The classic slips: « il peux » (wrong - il takes peut), « je peut » (wrong - je takes peux), and « un peut de sucre » (wrong - quantity is peu). The quantity word peu builds essential expressions worth learning as blocks: un peu de (a little), peu à peu (little by little), à peu près (approximately), depuis peu (recently). None of them ever takes a t or an x. One more trap: the question form « Puis-je...? » replaces peux in inversion - « Peux-je » does not exist - which is why polite requests sound different from the conjugation table learners memorised.
On peut se tutoyer, non ?
We can use tu with each other, right?
On → peut, like il/elle.
Ajoute un peu de crème, pas trop.
Add a little cream, not too much.
Quantity - peu, invariable.
Frequently asked
Why do peut, peux, and peu sound the same?
French frequently drops the final consonant sound, so pouvoir forms and the adverb peu converge on a similar pronunciation even though they are unrelated words.
Is there a quick way to remember peux vs peut?
Je and tu (the "closer" subjects) both end in x: peux. Il, elle, and on end in t: peut.
