Exercise the veto? (4)
I believe the answer is:
vote
'exercise the veto?' is the definition.
The answer and definition can be both acts as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'exercise the veto?' is the wordplay.
'exercise' indicates anagramming the letters (I've seen 'exercising' mean this).
'veto' with letters rearranged gives 'VOTE'.
Can you help me to learn more?
(Other definitions for vote that I've seen before include "What suffragettes wanted" , "Exercise choice" , "Mark choice in election" , "Cast a ballot" , "Poll" .)
