Show of hands, maybe (4)
I believe the answer is:
vote
'show of hands maybe' is the definition.
(I know that show of hands is a voting methods in deliberative assemblies)
This is the entire clue.
(Other definitions for vote that I've seen before include "Ballot, exercise of franchise" , "Mark choice in election" , "Make cross" , "Plebiscite" , "Poll" .)
