Beau or bon? French oral and nasal vowels in useful pairs
Compare beau/bon and paix/pain, then follow a short family tea-time scene. See how bon, bonne and peinte have three different vowel-and-consonant patterns.
In short
An oral vowel sends air mainly through the mouth; a nasal vowel also sends air through the nose. Compare beau /bo/ with bon /bɔ̃/: the initial /b/ stays, and the vowel changes. Bon ends in a nasal vowel; bonne /bɔn/ has an oral vowel followed by a pronounced /n/.

What is the difference between oral and nasal vowels?
beau /bo/ → bon /bɔ̃/beautiful → good
Focus: The first consonant stays /b/. The vowel category changes.
Le gâteau est beau.
The cake is beautiful.
Le gâteau est bon.
The cake tastes good.
paix /pɛ/ → pain /pɛ̃/peace → bread
Focus: The first consonant stays /p/. The second word has a nasal vowel.
Nous voulons la paix.
We want peace.
Nous achetons du pain.
We buy bread.
The /ɛ/ pronunciation of paix is the model for this comparison; some speakers use /e/. With beau and bon, the broad symbols also show a difference in vowel quality: /o/ and /ɔ̃/. Learn the complete target vowel for each word rather than keeping an English vowel and adding an ending.
- Léa
Ton gâteau est très beau !
Your cake is beautiful!
- Tante
Merci ! Tu veux une petite part ?
Thanks! Would you like a small slice?
- Léa
Oui, merci. Il est vraiment bon.
Yes, thanks. It’s really good.
- Tante
Et il reste du pain pour demain.
And there’s some bread left for tomorrow.
First Léa comments on the cake’s appearance with beau. After tasting it, she says bon. The two words have the same beginning and a different vowel. In the last line, pain ends with a nasal vowel too. The final letters help distinguish the words on the page; keep the vowel itself clear when saying them.
Words to put the contrasts in context
Find:
Three endings to keep separate
| Example | Structure | End of the word |
|---|---|---|
| bon /bɔ̃/ | Nasal vowel | Keep the vowel flowing; no final /n/. |
| bonne /bɔn/ | Oral vowel + /n/ | The tongue closes for /n/. |
| peinte /pɛ̃t/ | Nasal vowel + /t/ | Keep nasalisation, then make /t/. |
These endings give you a precise way to compare two attempts. If bon gains a strong final /n/, return to the first row. If peinte loses its /t/, return to the third. A following consonant and nasalisation are separate features, so listen for each one in a spoken model of the word.
