Here's a breakdown of the pronunciation:
* d: Pronounced like the "d" in "dog".
* ɑ̃: This is a nasal vowel sound. It's similar to the "an" in "pant" but with the air coming out of your nose.
You can try saying the sound "ah" while gently closing off your nasal passage with your finger. This will give you a sense of the "ɑ̃" sound.
Examples:
* Dans la rue: (dɑ̃ la ʁy) - In the street.
* Dans le jardin: (dɑ̃ lə ʒɑʁdɛ̃) - In the garden.
* Dans le cinéma: (dɑ̃ lə sinɛma) - In the cinema.
