Sport with clay disks (5)
I believe the answer is:
skeet
'sport with clay disks' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for skeet that I've seen before include "American clay pigeon shooting" , "US version of a shooting sport involving clay pigeons" , "Form of clay pigeon shooting" , "A form of clay-pigeon shooting" .)
