Found leading tennis match? (3,2)
I believe the answer is:
set up
'found' is the definition.
(thesaurus)
'leading tennis match?' is the wordplay.
'leading' means one lot of letters go next to another.
'tennis' becomes 'up' (I am not sure about this - if you are sure you should believe this answer much more).
'match?' becomes 'set' (matching is a kind of setting).
'up' after 'set' is 'SET-UP'.
Can you help me to learn more?
(Other definitions for set up that I've seen before include "Conspiracy" , "Erect; fix" , "Fool" , "An arrangement designed to trap or cheat" , "Arrangement; trick" .)
