Why writer stops working? Good you hear this about pen (7)
I believe the answer is:
oinking
'hear this about pen' is the definition.
The definition suggests a singular noun but the answer is not.
'why writer stops working? good' is the wordplay.
'why' becomes 'ink' (I can't explain this - if you can you should give a lot more credence to this answer).
'writer' becomes 'I' (the person who is writing these clues).
'stops' means one lot of letters goes inside another (stopping can mean blocking a gap).
'working?' becomes 'on' (on can mean working or activated).
'good' becomes 'g' (abbreviation).
'ink'+'i'='inki'
'inki' placed within 'on' is 'oinkin'.
'oinkin'+'g'='OINKING'
'you' acts as a link.
Can you help me to learn more?
(Other definitions for oinking that I've seen before include "farmyard noises" , "Noise from Tamworth" , "Sound from pen" .)
