If you heard the expression d’enfer, you’d be correct in thinking that it meant “of hell.” Literally, that’s what it means.
Informally, d’enfer can take on another meaning, though.
In a scene from La Galère, a teenager named Hugo is excited that he’s going to get a new apartment. But he’s not going to get just any old apartment — no, he’s going to get un appart d’enfer!
D’enfer can be added after a noun to mean amazing, awesome, wild…
Un appart is an informal way of saying un appartement. The final t in appart is pronounced.
Un appartement d’enfer, c’est cher!
An amazing apartment is expensive!
Tu vas avoir un appart d’enfer à Montréal!
You’re going to get an amazing apartment in Montreal!
