It'll give the bowler a break (4)
I believe the answer is:
spin
'a break' is the definition.
The definition and answer can be both acts as well as being singular nouns.
Maybe they are linked in a way I don't understand?
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for spin that I've seen before include "Turn round quickly" , "Jaunt" , "Swift whirling motion" , "Turn rapidly on axis" , "Give biased view" .)
