Figure name on a medal abbreviated (7)
I believe the answer is:
nonagon
'figure' is the definition.
(shape or figure with 9 sides)
'name on a medal abbreviated' is the wordplay.
'name on' becomes 'nona' (I am not sure about the 'on' bit.).
'a medal' becomes 'gong' (informal term for a medal or prize).
'abbreviated' means to remove the last letter (the word is shortened or abbreviated).
'gong' with its final letter taken away is 'gon'.
'nona'+'gon'='NONAGON'
Can you help me to learn more?
(Other definitions for nonagon that I've seen before include "Nine-sided figure" , "Figure with nine, twenty-one Dn" , "Figure with nine sides" , "Nine-sided polygon" , "Nine sided figure" .)
