Shot some thief for thievery (6)
I believe the answer is:
effort
'shot' is the definition.
(I know that shot can be written as effort)
'some thief for thievery' is the wordplay.
'some' indicates the answer is hidden within the clue (some of the parts of the word are used).
'EFFORT' can be found hidden inside 'thief for thievery'.
(Other definitions for effort that I've seen before include "Earnest attempt" , "For eft (anag.)" , "Attempt - hard work" , "Strenuous exertion" , "Hard mental or physical work" .)
