Fight with club that may be recycled (5,4)
I believe the answer is:
scrap iron
'fight with club that may be recycled' is the definition.
Although both the answer and definition are singular nouns, I can't see how one could define the other.
'fight with club' is the wordplay.
'fight' becomes 'scrap' (a scrap is a minor fight).
'with' says to put letters next to each other.
'club' becomes 'iron' (type of golf club).
'scrap'+'iron'='SCRAP-IRON'
Can you help me to learn more?
(Other definitions for scrap iron that I've seen before include "Discarded metal" , "Waste metal for melting down" , "rubbish" , "for recycling" .)
