Almost catch ball in the stadium watching the game (10)
I believe the answer is:
attendance
'the game' is the definition.
The definition and answer can be both acts as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'almost catch ball in the stadium watching' is the wordplay.
'almost' means to remove the first letter.
'catch' becomes 'rat' (ratting is a kind of catching).
'ball in the stadium watching' becomes 'tendance' (I am not sure about this - if you are sure you should believe this answer much more).
'rat' with its first letter taken away is 'at'.
'at'+'tendance'='ATTENDANCE'
Can you help me to learn more?
(Other definitions for attendance that I've seen before include "how many are watching?" , "Number at gathering" , "People present" , "Act of being present" , "Service" .)
