I think they were saying the second "t" in appétit is silent (which it is), not the one in petite.

I understand; I said “near-silent” because I don’t know of a better way to describe it (diminished? unemphisised? 🤷🏻‍♂️)

Mind you, my experience with French is mostly limited to Duolingo and Google Translate - and could very well be wrong.

I was aiming for teeth, so that’s on me for only including one! 😅
