Ley has stroke on court (4,6)
I believe the answer is:
half volley
'court' is the definition.
Although both the answer and definition are singular nouns, I cannot understand how they can define each other.
'ley has stroke on' is the wordplay.
'ley has' becomes 'half' (I am not sure about this - if you are sure you should believe this answer much more).
'stroke' becomes 'volley' (volley is a kind of stroke).
'on' is a charade indicator (letters next to each other).
'half'+'volley'='HALF-VOLLEY'
Can you help me to learn more?
(Other definitions for half volley that I've seen before include "Stroke hitting ball just after it bounces" , "Tennis shot" .)
