Sloth, say (6,3)
I believe the answer is:
deadly sin
'sloth say' is the definition.
(sloth is a kind of deadly sin)
This is all the clue.
(Other definitions for deadly sin that I've seen before include "envy for example" , "Lethal lapse like pride, gluttony or envy" , "Anger, say" , "greed, or lust" , "It's one of seven, gluttony say" .)
