Arranging coal after, very outspoken (5)
I believe the answer is:
vocal
'outspoken' is the definition.
(I know that outspoken can be written as vocal)
'arranging coal after very' is the wordplay.
'arranging' indicates an anagram.
'after' is a charade indicator (letters next to each other).
'very' becomes 'v' (abbreviation).
'coal' anagrammed gives 'ocal'.
'ocal' after 'v' is 'VOCAL'.
(Other definitions for vocal that I've seen before include "speaking loudly" , "With lots to say" , "Given to speech, often in protest" , "Loud in complaining" , "For, giving, voice" .)
