Enneagon


In geometry, an enneagon, also spelled eneagon,  is a polygon or plane figure with nine angles and nine sides; a nonagon.


Because nonagon and eneagon (with one initial n) have the same number of letters this word is sometimes used to trip up those doing crosswords!

    So, what IS the correct spelling? Or doesn't it matter? Thinking along the lines of octagon etc., I'd automatically suppose that nonagon was the correct word. The people who like to trip others up doing crosswords would certainly be successful with me!

      Either spelling is correct according to the dictionary.

    Ha! I knew that - today! Why? Because I was trying to explain a dodecahedron to Catriona on Monday. Follow?
