How do you pronounce un smoking?
Le smoking means tuxedo in French. I'm just wondering, is the 'g' pronounced?
The "ng" sound, ⟨ŋ⟩ in IPA, is really weird... but it's equally weird in both French and English! For example, if you go to https://en.wiktionary.org/wiki/sing and listen to the recordings, you may also be uncertain if you hear a "g" at the end of "sing". You've just likely never thought about how you say it. Well, it's the same exact sound in French.
You actually have a bit more wiggle room in French, because this consonant only appears in loanwords such as "smoking", "camping", "shampooing", and so on. So it's a rare sound that many people have trouble with, and you'll be well-understood even if you say it wrong. On one extreme, you can put a very definite "g" at the end of "smoking". On the other, you can pronounce it like the "n" in "nyeh nyeh nyeh" (or like the "gn" in "agneau"). Neither is correct, but both are good enough.
