"Le bruit était infernal" - what does "infernal" mean? (Can't be sure of spelling)?

[mmmmmmmmmmmmmmmmšm]

I'm listening to a French exam CD and I heard a phrase which sounded something like "Le bruit était infernal". The woman speaking is talking about aircraft noise. But I have no idea what "infernal" means or how it's spelt. Can anyone help me?

LOL! How embarrassing that I didn't even know the word exists exactly the same in English. Thanks for letting me know.

They were saying that the noise was hell-like. We'd say in conversational English 'the noise was a nightmare!' or 'the noise was horrendous'. The adjective 'infernal' is more formal in English; lots of our posh English words are French words we've borrowed lol.

If you say, 'c'est de l'enfer!' - it's a nightmare. Literally, 'it's hell'. Le bruit de l'enfer would be another way of saying 'le bruit infernal'.

Good luck. =)
