Share given to girl with sword (7)
I believe the answer is:
cutlass
'sword' is the definition.
(type of sword)
'share given to girl with' is the wordplay.
'share' becomes 'cut' (cut is a kind of share).
'given to' means one lot of letters go next to another.
'girl with' becomes 'lass' (I've seen this in other clues).
'cut'+'lass'='CUTLASS'
(Other definitions for cutlass that I've seen before include "Pirate's sword" , "Curved sailors' sword" , "Old sailor's sword" , "Short, heavy curved sword" , "Sword formerly used by sailors" .)
