Everywhere in the world except in a part of France the French speaking people prononce the un correctly and not like a in.

@@gide5489 There's no correct or incorrect, mergers are part of most varieties of most languages

@@ArturoSubutex In France we have an organisation called "Académie Française" which is in charge of the language. They also have a dictionary, and they are clear on this point, there are 4 nasal sounds in French and "un" is pronounced as œ̃ and not ɛ̃ (in). PS: A reason more subjective is that pronouncing "in" instead of un in words like parfum is ugly.

@@gide5489 L'Académie française isn't "in charge of the language"; it gives recommendations and opinions ("recommandations et avis"). It also happens to include zero linguists, zero lexicographers and just 2 philologists. Make no mistake, most of them are capable writers and I don't mind them giving their opinion. But, unsurprisingly, they haven't finished a dictionary in almost a century (1935). They can tell what they want, but in today's dominant variety of Standard French, /ɛ̃/ and /œ̃/ have merged. If you listen carefully to journalists, politicians, or even Académie française members, most won't distinguish between the two (they probably don't even notice it because, well, they're not linguists and have zero idea about how languages actually work). I also regret it, I like the brin/brun distinction. But it's a linguistic fact that the merger is now dominant.

@@ArturoSubutex Go to Québec, Belgium, Switzerland, Africa, DOM-TOM, and tell ma about what is dominant. Concerning what you call south of France, listen to Louane when she sings Jour un She is from the "pas de Calais" (North) or to Saez, he is from Savoie, etc.
