Cheeky Girls number in medleys (6)
I believe the answer is:
minxes
'cheeky girls' is the definition.
'number in medleys' is the wordplay.
I cannot really understand how this works, but
'number' could be 'x' (X is an example) and 'x' is found in the answer.
'in' is within the answer.
The remaining letters 'mes' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for minxes that I've seen before include "Seductive women" , "Cheeky or mischievous girls" .)
