Encouraging word for Charlie's predecessor (5)
I believe the answer is:
bravo
This clue is a double definition.
'encouraging word' is the first definition.
(I've seen this in another clue)
'charlie's predecessor' is the second definition.
(in the NATO phonetic alphabet)
'for' is the link.
(Other definitions for bravo that I've seen before include ""Well done, old chap!"" , "next to alpha" , "Exclamation of approval" , "Jolly good" , "International Call Sign: appreciation shown at the opera" .)
