A cry from Leo (3)
I believe the answer is:
'a cry' is the definition.
I don't know anything about this answer so I cannot tell whether it can be defined by this definition.
'from leo' is the wordplay.
'from' is an anagram indicator (from the letters).
'leo' with letters rearranged gives 'OLE'.
Can you help me to learn more?
(Other definitions for ole that I've seen before include "Madrid exclamation" , "Spanish cheer" , "Hurray in Spain" , "Spanish hurrah!" , "Hurry in Spain" .)
