Steal from the Waterloo terminus (4)
I believe the answer is:
loot
'steal' is the definition.
(I know that loot is a type of steal)
'from the waterloo terminus' is the wordplay.
'from' says the answer is hidden in the clue.
'LOOT' is hidden in the letters of 'waterloo terminus'.
(Other definitions for loot that I've seen before include "Stolen goods" , "Plunder - booty" , "familiar officer" , "Booty; sack" , "Steal (goods); money" .)
