Cub Scout leader (5)
I believe the answer is:
akela
'cub scout leader' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for akela that I've seen before include "Adult leading cubs" , "Leader of pack of Cub Scouts - she-wolf in "The Jungle Book"" , "Adult Cub Scout leader" , "Cub Scout pack leader" , "Leader of group" .)
