Points out a menial worker for punishment (6)
I believe the answer is:
whacks
'worker for punishment' is the definition.
I can't tell whether this defines the answer.
'points out a menial' is the wordplay.
'points' becomes 'WW' (an abbreviation for a compass point written twice).
'out' means to remove the last letter.
'a menial' becomes 'hacks' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'ww' with its last letter taken away is 'w'.
'w'+'hacks'='WHACKS'
Can you help me to learn more?
(Other definitions for whacks that I've seen before include "Defeats heavily" , "Hits hard" , "'Lizzie Borden with an axe, gave her mother 40 ......'" , "Resounding blows" , "Hard blows" .)
