18 = octocaedecagon

[Jack8rkin]

Hey!
What could I call a hole that is shaped like an octocaedecagon (a figure that has 18 sides) in a less sofisticated way?
Can I say 18-facet hole/opening?

Thanks

It's an 18-sided hole.

I don't think the word "octadecagon" is sophisticated but I think it would sound pompous if you used it in normal everyday speech. Most people wouldn't know how many sides it had so if you said "18-sided" no-one would be confused.

I think Jack8rkin's spelling is probably attested too; this would fit the Gk 18: όκτоκαιδεκα .

I was just thinking that the middle section would be more likely to translate to "kai" than "cae".

I just copied and pasted the word from the Multitran dictionary I use.

I'm sure there are probably multiple acceptable possibilities because Greek doesn't use the same alphabet, there won't be just one single written translation.
