The phrase ‘sounds good’ can be translated to French as ‘ça sonne bien‘.
In everyday conversations, this expression is used to convey agreement or approval, similar to how you would use it in English when you want to confirm that something seems positive or acceptable. For instance, if someone suggests a plan or an idea that you like, you can respond with ‘ça sonne bien’ to express your enthusiasm.
Keep in mind that tone and context matter in both languages, so combine it with a smile or nod to emphasize your agreement!
