French /ø/ vs /œ/
peu vs peur: the two sounds hiding inside "eu"

French "eu" is not one sound. It's two. Peu and peur look almost the same on paper but use entirely different vowels. The split follows a simple pattern most learners never get told — and once you know it, you'll hear the difference immediately.

This contrast is the most subtle of the French eu vowels. Both are front-rounded. The only physical change is jaw height — about one millimeter. The ABX drill sharpens your perception before your tongue even has to figure out what to do.

The problem

Two vowels, one spelling, zero English equivalent

Both /ø/ and /œ/ are front-rounded vowels. Neither exists in English. Learners who worked to master "eu" usually built one mental category — one sound, one spelling. Finding out there are actually two sounds in the same spelling forces a recalibration.

The physical difference is minimal: /ø/ is close-mid (jaw nearly shut), /œ/ is open-mid (jaw opens one notch, about one millimeter). The acoustic difference is real and consistent, but it requires trained attention to catch.

There is one more wrinkle: in conversational Parisian French, native speakers are increasingly neutralizing this distinction. So you may not always hear it in natural speech. But for formal French, classical diction, opera, and theater, the distinction is maintained and matters.

Closed /ø/ — open syllable

When "eu" ends the syllable with no following pronounced consonant, it is /ø/.

Open /œ/ — closed syllable

When a pronounced consonant follows "eu" in the same syllable, it is /œ/.

The rule

The position rule — one rule, most cases covered

/ø/
Open syllable

No pronounced consonant follows the eu in the same syllable.

peu, deux, feu, jeu, bleu
/œ/
Closed syllable

A pronounced consonant follows and closes the syllable.

peur, fleur, cœur, jeune, seul

This rule covers approximately 85-90% of cases. Exceptions exist — notably "yeux" (/jø/, eyes) follows the open syllable pattern, and a few formal words deviate — but the rule is reliable enough to build on.

Production: the one-millimeter shift

For /ø/: tongue forward and raised, lips tightly rounded, jaw almost shut. For /œ/: keep everything the same, drop your jaw by one millimeter, relax the lips very slightly. That small opening is the whole difference.

The famous minimal pair: jeûne vs jeune

Jeûne /ʒøn/ = a fast (not eating). Jeune /ʒœn/ = young. These are the most-cited /ø/-/œ/ minimal pair in French phonetics literature. Both are common words.
