Writer’s hoarding record set of guns? (6)
I believe the answer is:
biceps
'set of guns?' is the definition.
'biceps' can be an answer for 'guns?' (I've seen this in another clue). I am not certain of the 'set of' bit.
'writer's hoarding record' is the wordplay.
'writer's' becomes 'bic's' (Bic is a manufacturer of pen).
'hoarding' is an insertion indicator.
'record' becomes 'EP' (abbreviation for extended play record).
'bics' going around 'ep' is 'BICEPS'.
Can you help me to learn more?
(Other definitions for biceps that I've seen before include "Muscle that flexes the forearm" , "Contractor" , "Large upper arm muscle" , "I bend the elbow" , "Elbow-bending muscle" .)
