Breakdown of Bon appétit !
Questions & Answers about Bon appétit !
A good approximation is boh-nah-pay-TEE.
More precisely in French IPA, it is /bɔ.na.pe.ti/.
A few pronunciation points:
- bon does not sound like English bon in bonnet
- the on in bon is nasal when the word stands alone, but in this phrase it links into the next word
- appétit has the stress pattern of French, which is much flatter than English, with a slight emphasis at the end
- the final t in appétit is silent
So if you want a natural learner-friendly version, boh-nah-pay-tee is a solid start.
