Funny figures in black rock (7)
I believe the answer is:
comical
'funny' is the definition.
(I know that funny can be written as comical)
'figures in black rock' is the wordplay.
'figures' becomes 'mic' (I am not sure about this - if you are sure you should believe this answer much more).
'in' indicates putting letters inside.
'black rock' becomes 'coal'.
'mic' going inside 'coal' is 'COMICAL'.
Can you help me to learn more?
(Other definitions for comical that I've seen before include "Rich" , "'Amusing, funny (7)'" , "Amusing or droll" , "priceless" , "Humorous" .)
