Does it mean you've finished bowling? (4)
I believe the answer is:
over
'bowling?' is the definition.
(cricket term)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for over that I've seen before include "Round of six bowls in cricket - then it's finished" , "Bout of six bowls in cricket" , "A bowler's round in cricket" , "completed" , "Finished, done" .)
