Evidence when watching big game in person? (6)
I believe the answer is:
attest
'evidence' is the definition.
(attesting is a kind of evidencing)
'watching big game in person?' is the wordplay.
I cannot really see how this works, but
'game' could be 'test' (I have seen 'big game' mean 'test' so perhaps 'game' could also mean 'test') and 'test' is present in the answer.
The remaining letters 'at' is a valid word which might be clued in a way I don't see.
This may be the basis of clue (or it may be nonsense).
'when' acts as a link.
Can you help me to learn more?
(Other definitions for attest that I've seen before include "Swear to" , "Declare (that something is the case)" , "Give testimony in a court of law" , "Certify or bear witness" , "Sign on" .)
