Funny business with figures (5)
I believe the answer is:
comic
'funny' is the definition.
(comic can mean funny or humorous)
'business with figures' is the wordplay.
'business' becomes 'co' (short for company).
'with' says to put letters next to each other.
'figures' becomes 'mic' (I am not sure about this - if you are sure you should believe this answer much more).
'co'+'mic'='COMIC'
Can you help me to learn more?
(Other definitions for comic that I've seen before include "Stand-up comedian" , "Garden perhaps" , "SECOND PART OF 16" , "Children's periodical" , "Comedian - humorous - children''s magazine" .)
