IN vs UN: sharpening the contrast (advanced ear training)
Improve comprehension by training the subtle difference between IN and UN in careful speech.
What you’ll learn Improve comprehension by training the subtle difference between IN and UN in careful speech.
Key ideas (keep these in your head) • Many accents merge IN and UN; but careful contrast training improves listening. • Use anchor words and compare in short phrases rather than isolated sounds. • Aim for consistency over perfection: your ear is the real win here.
Real examples (French → what you often hear → English) • C’est un vin. → c’est un vin → It’s a wine. • Un lundi matin. → un lundi matin → A Monday morning. • Il est brun. → il est brun → He is brown-haired.
Drills in vin, matin, plein un un, brun, lundi
Common mistakes (and quick fixes) • Trying to force a huge difference and sounding unnatural. Fix: keep it subtle; prioritise recognition. • Dropping nasalisation entirely. Fix: maintain nasal resonance even if contrast is small.
Quick self-check Record: vin / un / brun / plein. Check: do you maintain nasal quality consistently?
About this lesson
How to practise “IN vs UN: sharpening the contrast (advanced ear training)”
This lesson is part of the Pronunciation series on Chase in French. Train your ear and mouth on the sounds that make French French — nasal vowels, liaison, the R, and the rhythm patterns native speakers actually use.
Follow the Ears → Mouth → Eyes method: first listen to how native speakers say it, then repeat it out loud until it feels natural, and only then look at the spelling. Short, repeated practice over several days beats one long session.
Want guided feedback on your accent? The Chase in French Academy and live classes turn lessons like this into structured training, and the weekly podcast lets you hear these patterns in real conversation.
