Sadly dine out, showing greed? (6,3)
I believe the answer is:
deadly sin
'greed?' is the definition.
(greed is a kind of deadly sin)
'sadly dine out' is the wordplay.
'out' indicates an anagram (out can mean wrong or inaccurate).
'sadly'+'dine'='sadlydine'
'sadlydine' with letters rearranged gives 'DEADLY SIN'.
'showing' acts as a link.
(Other definitions for deadly sin that I've seen before include "not good - bad" , "Greed, perhaps" , "Anger, covetousness, envy, gluttony, lust, pride or sloth" , "Eg, lust or pride" , "Anger, say" .)
