What you'll learn
Say “song” and stop right before the ng — that buzzing, nose-routed vowel is roughly what French does on purpose, all the time. Un bon vin blanc (a good white wine) contains four nasal vowels and zero pronounced n’s. Here’s the whole system — it’s smaller than it looks.
👃 Three sounds, one rule
Standard French keeps three nasal vowels: /ɑ̃/ as in an, en — /ɔ̃/ as in on — /ɛ̃/ as in in, ain, un. The n or m is not pronounced; it is only the signpost telling the vowel to go through the nose. Say « bon » and if your tongue touches for the n, it’s not French yet.

The three sounds of modern French
| Sound | Spellings | Words | Mouth |
|---|---|---|---|
| [ɑ̃] “ahn” | an, en, am, em | dans, vent, temps, chambre | open wide, drop the jaw |
| [ɔ̃] “ohn” | on, om | bon, mon, nom, tomber | round lips hard, like o |
| [ɛ̃] “ehn” | in, im, ain, ein, un | vin, pain, plein, brun, bien | smile slightly, mouth half-open |
(Textbooks list a fourth, [œ̃] for « un » — most of France merged it into [ɛ̃] decades ago. Un = “ehn” and nobody blinks.)
The n is a lie
The written n or m only marks nasality — your tongue never touches for it. Bon = [bɔ̃], tongue stays down. The moment you actually pronounce the n, you’ve said bonne — a different word. That pair (and vin/vine, an/âne) is the highest-value minimal pair drill in French.
When the nasal breaks
Add a vowel or a second n/m after, and the vowel de-nasalizes: bon → bonne, vin → vigne, an → année, brun → brune. This is exactly how masculine/feminine pairs sound different: américain [ɛ̃] → américaine [ɛn].
Test sentence
« Un bon vin blanc » = [œ̃/ɛ̃] [ɔ̃] [ɛ̃] [ɑ̃] — all three sounds in four syllables. If a French person smiles when you say it, you’ve earned the smile.

✍️ Your turn: trust your nose
Which nasal vowel is in « pain »? (bread)
Show answer
/ɛ̃/ — ain spells the same sound as in, ein, un.
« vent », « vont », « vin » — how many different vowels? (minimal trio)
Show answer
Three: /ɑ̃/, /ɔ̃/, /ɛ̃/ — wind, (they) go, wine. If they sound alike, slow down and exaggerate.
Why is there no nasal in « bonne »? (double n)
Show answer
The vowel is followed by nn + e, so it stays oral: /bɔn/. Same for « année », « immense ».
Is the n pronounced in « bon ami »? (liaison)
Show answer
Yes — in liaison the n surfaces and the vowel often loses its nasality: bo-na-mi.
Do the French still say /œ̃/ in « un »? (un vs in)
Show answer
Most speakers in France merge it into /ɛ̃/; the South and Belgium keep the distinction. Either is understood.
FAQ
How is « en » in “en été” different from “vent”?
Same [ɑ̃] sound — but in « en été » liaison adds an n-bridge to the next vowel: an-n-été. The vowel stays nasal; the liaison n belongs to the next syllable.
Why does « bien » sound like “byen”?
The i becomes a y-glide before the nasal: bien = b + y + [ɛ̃]. Same in rien, chien, viens.
Do accents ever appear on nasal vowels?
No — accents and nasality never stack on the same letter. Where the accents DO go is here: French accent marks.
How can I practise hearing the three vowels apart?
Minimal trios: banc / bon / bain, sans / son / sain, lent / long / lin. Say each trio aloud daily for a week — the contrast installs faster through your own mouth than through your ears.
Why does « parfum » not rhyme with « brun » for some speakers?
Both end in the old /œ̃/. Speakers who keep that vowel rhyme them; speakers who merged it say /ɛ̃/ in both. Pick one system and be consistent — mixing is what sounds odd.
