Girl - is she French? (7)
I believe the answer is:
estelle
'girl' is the definition.
'she french?' is the wordplay.
I cannot really see how this works, but
'she' could be 'estell' and 'estell' is located in the answer.
A single letter 'e' remains which might be clued in a way I don't understand.
This explanation may well be incorrect...
'is' is the link.
Can you help me to learn more?
(Other definitions for estelle that I've seen before include "Lets Lee produce a girl's name" , "Star girl" .)
