Desire and bend low for weapon (7)
I believe the answer is:
longbow
'for weapon' is the definition.
(longbow is a kind of weapon)
'desire and bend low' is the wordplay.
'desire' becomes 'long' (longing is a kind of desiring).
'and' says to put letters next to each other.
'bend low' becomes 'bow' (bowing is a kind of bending. I am not sure about the 'low' bit.).
'long'+'bow'='LONGBOW'
Can you help me to learn more?
(Other definitions for longbow that I've seen before include "Archer's weapon" , "missile-launcher" , "Powerful wooden weapon used against the French at Agincourt" , "Ancient weapon" , "Robin Hood's weapon" .)
