I can't tell whether this is a puzzle for the list to enjoy puzzling over,
or whether it's something you want answered. I doubt that I'm spoiling
anyone's fun by suggesting that the answer is "lune".

Is a figure on the surface of a sphere properly called a polygon? I don't
know the answer, but would like to. Anyone?
