An assent from the assenters (4)
I believe the answer is:
ayes
'the assenters' is the definition.
I don't know anything about this answer so I cannot judge whether this works.
'an assent' is the wordplay.
'an' becomes 'a'.
'assent' becomes 'yes' (I've seen this in another clue).
'a'+'yes'='AYES'
'from' acts as a link.
Can you help me to learn more?
(Other definitions for ayes that I've seen before include "The yes-votes at committee meeting" , "The yes votes at committee meeting" , "Nautical positive responses" , "Affirmative votes as in committee" , "Voting assents" .)
