Girls and men said to be different (7)
I believe the answer is:
maidens
'girls' is the definition.
(maiden is a kind of girl)
'men said to be different' is the wordplay.
'to be different' indicates an anagram (I've seen 'is different' mean this).
'men'+'said'='mensaid'
'mensaid' with letters rearranged gives 'MAIDENS'.
'and' acts as a link.
(Other definitions for maidens that I've seen before include "bowlers like?" , "Misses" , "one can't score off" , "Girls in general..." , "Unmarried girls" .)
