Group at a higher level, found (3,2)
I believe the answer is:
set up
'found' is the definition.
(found can mean to set up or establish)
'group at a higher level' is the wordplay.
I cannot quite understand how this works, but
'group' could be 'set' (both can mean a collection) and 'set' is found within the answer.
'higher' could be 'up' and 'up' is found within the answer.
No letters remain.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for set up that I've seen before include "advantageous position at Wimbledon?" , "Organise; mount" , "Contrived situation" , "An arrangement designed to trap or cheat" , "The way something is arranged" .)
