Pouch; steal (6)
I believe the answer is:
This clue is a double definition.
'pouch' is the first definition.
(I know that pouch can be written as pocket)
'steal' is the second definition.
(I know that steal can be written as pocket)
(Other definitions for pocket that I've seen before include "Snooker target; pouch" , "Small isolated group" , "Take unlawfully" , "Electronic maths aid" , "Take for oneself" .)
