Pluck and steal off with (6)
I believe the answer is:
spirit
'pluck' is the definition.
(I've seen this in another clue)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for spirit that I've seen before include "The non-physical part of a person" , "Distilled liquor" , "rum, perhaps" , "Brandy" , "Spectre - alcohol" .)
