In short
Some speakers distinguish brun /bʁœ̃/ from brin /bʁɛ̃/; many pronounce both with /ɛ̃/. Keep the different spellings and meanings whichever pattern you follow. Une /yn/ is a separate case: an oral vowel followed by a pronounced /n/.
Yellow the idea to rememberBlue French to learn
- brun / brinAlways two different soundsTwo words; the vowel contrast depends on the speaker
Mon frère est brun. Il tient un brin d’herbe.My brother has dark hair. He is holding a blade of grass.
Learn brun as an adjective and brin as a masculine noun. A speaker can pronounce them alike and still use both words.
- un / uneThe same nasal vowel with an extra endingA nasal vowel versus /y/ + /n/
J’ai un cousin et une cousine.I have a male cousin and a female cousin.
In une /yn/, pronounce /n/. In the article un, the tilde in /œ̃/ or /ɛ̃/ marks a nasal vowel, rather than a separate /n/.
- parfumA word ending in a spoken /m/A word ending in a nasal vowel
Ce parfum est léger.This fragrance is light.
The final -um belongs to the same historical vowel set as un and brun. Learn the word with its ending /œ̃/ or the merged /ɛ̃/.
| Word | Contrast retained | Categories merged |
|---|---|---|
| brun | /bʁœ̃/ | /bʁɛ̃/ |
| brin | /bʁɛ̃/ | /bʁɛ̃/ |
| un | /œ̃/ | /ɛ̃/ |
| une | /yn/ | /yn/ |
A merger changes a sound distinction, not the meaning of the words. The full phrase usually makes the meaning clear: des cheveux bruns describes hair, while un brin d’herbe names a blade of grass. When you compare two speakers, listen to several words from the set. One word gives you less to work with than un, brun and parfum together.
