I think layer is quite correct. Both Photoshop and sketch approach it the right way. Think of a sheet of paper as a layer. In Photoshop layers are sheets of paper that each matches the size of the document. On each paper you can draw whatever you want. They then lay on top of each other and the white parts are transparent.

In sketch, instead of sheets of paper that match the size of the document, you have a perfectly cutout shape for each stroke you draw. You can then move that cutout around within the document.

Both of those have the same principle except one is cutout one is not.

I agree that layer is correct, though I understand where there might be some “intuition clash” with people who are used to the classic paradigm.

When each layer is a transparent sheet it has an absolute Z order that translates 1-1 with the physical thing it’s virtualizing (transparencies, probably from traditional animation).

However if you cut out tiny shapes and arrange them with some on top of others to make a larger composition, there is no longer an absolute Z order to any element because there are a bunch of smaller stacks of various heights.

The virtualization no longer translates to the physical world, and from my experience that disconnect can sour people against a new way of doing things, regardless of whether it’s better.
