Watched United after contest (6)
I believe the answer is:
viewed
'watched' is the definition.
(viewing is a kind of watching)
'united after contest' is the wordplay.
'united' becomes 'wed' (I've seen this before).
'after' says to put letters next to each other.
'contest' becomes 'vie' (I've seen this before).
'wed' put after 'vie' is 'VIEWED'.
(Other definitions for viewed that I've seen before include "Looked at, inspected" , "seen on TV" , "Considered or deemed to be" , "Observed" , "Watched" .)
