Little bit of a steal (5)
I believe the answer is:
pinch
This clue is a triple definition!
'little' is the first definition.
(thesaurus)
'bit' is the second definition.
(thesaurus)
'of' is a link.
'a steal' is the third definition.
(pinch can mean to steal)
(Other definitions for pinch that I've seen before include "Steal - a little salt, for example" , "Grip sharply; steal" , "collar" , "Steal (informal); squeeze" , "Tweak" .)
