This is the 1896th most frequent French word.
poche
"Pocket."
Here, 'poche' is used as a noun referring to a common object, the pocket of clothing, showing its physical use in storing items.
J'ai mis mon téléphone dans ma poche.
I put my phone in my pocket.
Again, 'poche' as a noun is used to describe a feature of the pants, indicating not just its existence but also an additional aspect.
Il a acheté un pantalon avec une poche supplémentaire.
He bought pants with an extra pocket.
In this sentence, 'poches' again serves as a noun in the plural form to describe components of a jacket designed for storage, emphasizing their characteristic (being deep).
