What is a good way to ask "What is the French for this?" (while pointing at an object)
You can express that in different ways:
- Comment exprime-t-on ceci en français? : How do we express this in French?
- Comment appelle-t-on ceci en français?: How do we call this in French?
- Quel est l'équivalent français de ceci?: What's the French equivalent of this?
- Quel est l'équivalent de ceci en français ?: What's the equivalent of this in French?
The other answer is perfect if you need to write it, but it's a little too "formal" for a regular conversation.
You could use : "Comment appelle-t-on ça (or cela, but that's more formal) en Français". Which translates to : "How do you call [...] in French?".
You could say "Quel est l'équivalent en français de ". It means "What's the French equivalent to ". This would be a good way to ask for a "translation" of a word.
