Difference Between 'Work Area' and 'Workspace' in Adobe InDesign?

I've been reading Adobe InDesign Classroom in a Book 2026, and I noticed that the book uses "work area" and "workspace" as two distinct terms — seemingly intentionally.

The book defines them as follows:

• Work area: "The InDesign work area encompasses everything you see when you first open or create a document." — described as distinct from the Home screen.
• Workspace: "The configuration of the panels in the work area is referred to as the 'workspace'." — i.e., a named preset of panel arrangements, selectable from Window > Workspace (such as Essentials or Typography).

This distinction makes a lot of sense to me. The Home screen and the work area seem to be treated as two separate, opposing states of the application — and "workspace" is reserved specifically for panel layout presets.

However, Adobe's online manual defines workspace much more broadly:

"To create and manage documents in Adobe Creative Cloud applications, you can use various elements, such as panels, bars, and windows. Any arrangement of these elements is called a workspace."

— which seems to collapse the two concepts into one.

A few questions:

1. Do you recognize this distinction between "work area" and "workspace" in your own usage?
2. Is there an established term for the editing interface as a whole — the screen state that is the opposite of the Home screen?
3. When you click the back arrow next to the InDesign icon on the Home screen to return to your document, what do you call where you're returning to?

I'd be curious whether this is a distinction that InDesign professionals actually make in practice, or whether "workspace" is simply used loosely for both concepts.
