Drive off with some rare pelicans (5)
I believe the answer is:
repel
'drive off' is the definition.
(synonyms)
'with some rare pelicans' is the wordplay.
'with' says the answer is hidden in the clue.
'REPEL' is hidden in the letters of 'some rare pelicans'.
(Other definitions for repel that I've seen before include "Parry" , "push off" , "Drive back or disgust" , "Drive back or away" , "Fill with distaste" .)
