Run away from antelopes (5)
I believe the answer is:
elope
'run away' is the definition.
(I've seen this in another clue)
'from antelopes' is the wordplay.
'from' says the answer is hidden in the clue.
'ELOPE' is hidden within 'antelopes'.
(Other definitions for elope that I've seen before include "Run away in secret" , "Flee to wed" , "escape" , "Run away to Gretna Green?" , "Run away with lover" .)
