Took without permission (5)
I believe the answer is:
stole
'took without permission' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for stole that I've seen before include "Pinched; shawl" , "Item of clothing" , "Garment worn over the shoulders" , "Wide scarf worn about the shoulders" , "Moved silently" .)
