Men supporting outspoken board member (8)
I believe the answer is:
director
'board member' is the definition.
(I've seen this before)
'men supporting outspoken' is the wordplay.
'men' becomes 'or' (I've seen this in other clues).
'supporting' says to put letters next to each other (in a down clue, some letters go below others).
'outspoken' becomes 'direct' ('direct' can be similar in meaning to 'outspoken').
'or' put after 'direct' is 'DIRECTOR'.
(Other definitions for director that I've seen before include "This person could be on board or in theatre" , "He makes films or runs companies" , "Company board member" , "Big cheese" , "He guides and shapes a play or film" .)
