Priest loves storing shabby clothes for Murphy (6)
I believe the answer is:
potato
'murphy' is the definition.
('potato' can be a synonym of 'murphy')
'priest loves storing shabby clothes' is the wordplay.
'priest' becomes 'p' (ecclesiastical abbreviation).
'loves' becomes 'oo'.
'storing' is an insertion indicator.
'shabby clothes' becomes 'tat'.
'oo' going around 'tat' is 'otato'.
'p'+'otato'='POTATO'
'for' acts as a link.
(Other definitions for potato that I've seen before include "E.g. King Edward" , "Root crop" , "Vegetable with eyes" , "French wine region" , "Inert person" .)
