Why isn't "adorez" or "adores" also correct?
Could it be "Laquelle aimes-tu fille?" What's the difference between "Laquelle" and "quelle "?
As I understand it lequel is "which one" and quelle is "which somthing". And here the something is listed, which girl.
Why is "..vous aimez? incorrect?
Because this is a question, so you need to use "aimez-vous"?
You could also use 'Quelle fille est-ce que vous aimez? '
Quelle fille que vous adorez? is not wrong.
How do you know which form of "which" to use?
