Game with two essential elements of tennis (7)
I believe the answer is:
netball
'tennis' is the definition.
The answer and definition can be both acts as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'game with two essential elements' is the wordplay.
'game' becomes 'ball game' (ball game is a kind of game).
'with' is a charade indicator (letters next to each other).
'two essential elements' becomes 'net' (I am not sure about this - if you are sure you should believe this answer much more).
'ball' put after 'net' is 'NETBALL'.
'of' acts as a link.
Can you help me to learn more?
(Other definitions for netball that I've seen before include "Seven-a-side team game -- all bent (anag)" , "Women's game" , "Sport whose players wear bibs" , "Team game for tall Ben" , "After this, you get to serve again" .)
