Cry of encouragement (3)
I believe the answer is:
ole
'cry of encouragement' is the definition.
(Spanish word used to encourage someone)
This is all the clue.
(Other definitions for ole that I've seen before include "Hurry in Spain" , "Well done! (Span.)" , "A Spanish hooray" , "Hooray in Spain" , "Spanish shout of triumph" .)
