Handyman one speaking after month (9)
I believe the answer is:
decorator
'handyman' is the definition.
(I've seen this before)
'one speaking after month' is the wordplay.
'one speaking' becomes 'orator' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'after' says to put letters next to each other.
'month' becomes 'dec' (abbreviation for December).
'orator' put after 'dec' is 'DECORATOR'.
Can you help me to learn more?
(Other definitions for decorator that I've seen before include "Painter perhaps" , "Who paints" , "Artisan" , "Eg, painter, wallpaperer" , "House painter" .)
