Fleece trouser pocket (5)
I believe the answer is:
steal
This clue might be a double definition.
'fleece trouser' is the first definition.
'steal' can be an answer for 'fleece' (thesaurus). I am not certain of the 'trouser' bit.
'pocket' is the second definition.
(I know that pocket can be written as steal)
Can you help me to learn more?
(Other definitions for steal that I've seen before include "bargain?" , "Creep" , "crib" , "Walk off with" , "Take unlawfully" .)
