Surface of loo roll absorbs (5)
I believe the answer is:
floor
'surface' is the definition.
(I know that floor is a type of surface)
'of loo roll absorbs' is the wordplay.
'absorbs' says the answer is hidden in the clue.
'FLOOR' is hidden within 'of loo roll'.
(Other definitions for floor that I've seen before include "Disconcert" , "Baffle, confound" , "Knock down - planking" , "Base of room - storey" , "Inside horizontal surface" .)
