Take flight to unite
I believe the answer is:
elope
'take flight to unite' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for elope that I've seen before include "Do a runner" , "Run away with lover" , "go off to the match?" , "do a moonlight flit" , "Abscond for amorous purposes" .)
