Who’s in favour of a penny off income tax system? (3)
I believe the answer is:
aye
'who's in favour' is the definition.
The definition suggests a singular noun which matches the answer.
'penny off income tax system?' is the wordplay.
'penny' becomes 'p' (short for pence).
'off' suggests deleting specific letters ('off' can mean to remove).
'income' becomes 'pay' (income from a job).
'tax system?' becomes 'e' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'pay' with 'p' removed is 'ay'.
'ay'+'e'='AYE'
'of a' acts as a link.
Can you help me to learn more?
(Other definitions for aye that I've seen before include "Positive voting response" , "Yes (archaic)" , "Yes vote" , "Yes; ever" , "An affirmative vote" .)
