On Skype I mentioned that I need a helper to hold the prism pole. I called =
the=20
prism "cibminra"; would "kubminra" be better?

A mathematical prism is a shape consisting of two congruent ends in differe=
nt=20
parallel planes, connected by sides which are all parallel to some line. An=
=20
optical prism is a transparent device with flat sides, not all of which are=
=20
parallel. Some optical prisms are mathematical prisms, such as the equilate=
ral=20
triangle prism used to split a beam into colors, but some aren't. The prism=
 in=20
the prism pole doesn't even have all sides flat. It's a circular cylinder w=
ith=20
three mutually perpendicular flat faces on the inside end and one flat face=
 on=20
the outside end.

So should we have more than one word for "prism"? What should they be?
