Virgin soldiers accepting assistance? (6)
I believe the answer is:
maiden
'virgin' is the definition.
(I know that virgin can be written as maiden)
'soldiers accepting assistance?' is the wordplay.
'soldiers' becomes 'men' (men can mean a group of soldiers).
'accepting' means one lot of letters goes inside another (inserted letters are accepted).
'assistance?' becomes 'aid' ('aid' can be a synonym of 'assistance').
'men' enclosing 'aid' is 'MAIDEN'.
(Other definitions for maiden that I've seen before include "Unmated; runless over" , "Female" , "Earliest - unmarried" , "Ship's first trip" , "When you get her" .)
