Outspoken men making an appearance (5)
I believe the answer is:
guise
'an appearance' is the definition.
(guise is a kind of appearance)
'outspoken men' is the wordplay.
'outspoken' indicates a 'sounds like' (homophone) clue.
'men' becomes 'guys' (guy can informally mean a man).
'guys' sounds like 'GUISE'.
'making' acts as a link.
(Other definitions for guise that I've seen before include "Appearance, semblance" , "Shape; pretence" , "Mask" , "Show" , "Semblance; likeness" .)
