How do you translate "hole" in the sense of an opening in a solid, as in
"there is a hole in my bucket!"?

I've used {kunti}. The area that constitutes the hole is {kunti lo <surrounding material>}. Another option would be {kutca'u} "empty area".

Yeah... But I'd still like to refer to the holes specifically, talk about their position and count them. By the way, how would you translate the bucket sentence?

selpa'i has used {nonselsfe}. I guess a sphere is a nonselsfe.

But a sphere has a surface. (4*pi*r^2)

I was thinking about sefta4. Should we pretend it never existed in the first place? I myself wrote {bolsfetai} in the past.

But even without sefta4, you can't escape the fact that the sphere as a (hyper)surface (in any dimension you want) doesn't have anything that could be called a sefta or a korbi.

{nonselsfe} is supposed to describe something that has no surface. I'm not sure what such a thing could be, other than a hole. But I might be missing something.

The only shapes in 3d space without surfaces or boundaries I can think of are 1d closed wires (circle), the 2d sphere, torus, double torus, triple torus, ..., and unbounded things like infinite wires, sheets or the space itself. This completely misses the point of holes.

I use
{korbi} for surfaces in general, but {nonselkoi} would be something
unbounded, or an open set in topology.

ue, I use {korbi} to talk about edges. :)

Well, edges are just a particular case.
