Swag (4)
'swag' is the definition.
(I know that swag can be written as loot)
This is all the clue.
(Other definitions for loot that I've seen before include "Stolen goods" , "Tool found among plunder" , "Tool for plundering" , "Steal (goods); money" , "Burglar's takings - pillage" .)
(Other definitions for matilda that I've seen before include "Roald Dahl book; girl" , "ended up burnt" , "Waltzing girl" , "Roald Dahl heroine" , "12th century English empress" .)
