Establish, initiate (3,2)
I believe the answer is:
set up
This clue is a double definition.
'establish' is the first definition.
(I know that establish can be written as set up)
'initiate' is the second definition.
(I know that initiate can be written as set up)
(Other definitions for set up that I've seen before include "Exalt - arrange - begin" , "Contrived situation" , "The way something is arranged" , "Arrangement; trick" , "advantageous position at Wimbledon?" .)
