Game in second half of June isn't shot (6)
I believe the answer is:
tennis
'game in second' is the definition.
'tennis' can be an answer for 'game' (tennis is a kind of game). I am unsure of the 'in second' bit.
'half of june isn't shot' is the wordplay.
'half of' means to take half the letters.
'shot' indicates anagramming the letters.
'june' with half the letters taken is 'ne'.
'ne'+'isnt'='neisnt'
'neisnt' with letters rearranged gives 'TENNIS'.
Can you help me to learn more?
(Other definitions for tennis that I've seen before include "Game for two or four" , "Game played on court" , "Table -, - elbow" , "Henman's game" , "- elbow; - shoe" .)
