Helen about to be announced in sport (7)
I believe the answer is:
netball
'sport' is the definition.
(netball is a sport)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for netball that I've seen before include "After this, you get to serve again" , "Game for women or girls" , "Women's game" , "Team sport" , "Team game/sport" .)
