Many males involved with girl (6)
I believe the answer is:
damsel
'girl' is the definition.
(I know that damsel is a type of maid)
'many males involved' is the wordplay.
'many' becomes 'd' ().
'involved' is an anagram indicator (involved can mean confusing or complex).
'males' is an anagram of 'amsel'.
'd'+'amsel'='DAMSEL'
'with' acts as a link.
(Other definitions for damsel that I've seen before include "Young woman (archaic)" , "(Poetically) a young unmarried woman" , "Young woman (often in distress)" , "Young single woman" , "Someone in distress?" .)
