Sword ignored by girl (7)
I believe the answer is:
cutlass
'sword' is the definition.
(type of sword)
'ignored by girl' is the wordplay.
'ignored' becomes 'cut' (I've seen this in other clues).
'by girl' becomes 'lass' (lass can informally mean a girl. I am not sure about the 'by' bit.).
'cut'+'lass'='CUTLASS'
Can you help me to learn more?
(Other definitions for cutlass that I've seen before include "Pirate sword" , "Sailor's blade" , "Short, heavy curved sword" , "Sword formerly used by sailors" , "Curved sailors' sword" .)
