Shrek royalties somewhat reflecting delivery (6)
I believe the answer is:
yorker
'delivery' is the definition.
(type of cricket delivery)
'shrek royalties somewhat reflecting' is the wordplay.
'somewhat' indicates the answer is hidden within the clue.
'reflecting' is a reversal indicator.
'rekroy' is hidden within 'shrek royalties'.
'rekroy' reversed gives 'YORKER'.
(Other definitions for yorker that I've seen before include "Ball pitching just under bat (cricket)" , "Delivery coming down late" , "Cricket delivery aimed at the feet" , "Delivery pitching directly under the bat" , "Bowler's stratagem (cricket)" .)
