Sporting event in truth nearly over (2,3)
I believe the answer is:
fa cup
'sporting event' is the definition.
The definition suggests a singular noun which matches the answer.
'truth nearly over' is the wordplay.
'truth' becomes 'fact' (fact can mean truth or reality).
'nearly' means to remove the last letter.
'over' becomes 'up' (e.g. if your time is up it is over).
'fact' with its last letter taken away is 'fac'.
'fac'+'up'='FA CUP'
'in' acts as a link.
Can you help me to learn more?
(Other definitions for fa cup that I've seen before include "competition" , "Football trophy" , "football tournament" .)
