Figure a man is many-sided (9)
I believe the answer is:
hexagonal
'many-sided' is the definition.
Although both the answer and definition are adjectives, I can't see how they can define each other.
'figure a man' is the wordplay.
'figure' becomes 'hexagon' (hexagon is a kind of figure).
'a man' becomes 'Al' (man's name).
'hexagon'+'al'='HEXAGONAL'
'is' acts as a link.
Can you help me to learn more?
(Other definitions for hexagonal that I've seen before include "with several sides" , "Shaped like the cells in a honeycomb" , "Six-sided like geometric figure" .)
