From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I didn't realise that people use them interchangeably. I've got an idea on what a WM is and what a DE is but nothing super in depth.
A WM is literally just the window manager. It makes windows work and have a border and maximize and stuff but that's it.
A DE gives you a lot of other stuff: a root window that makes up the "desktop", panels & widgets, notification area, an application menu, workspaces, window and workspace switchers, global hotkeys, the concept of a session and stuff related to it (things to run on start, or saving your session between reboots), a unified theme and fonts etc. etc.
There are also programs that fall somewhere between these. For example tiling WM tend to fill the whole screen so they don't care a lot about all the things I mentioned but they can integrate with some other stuff to some extent. Or something like OpenBox which includes a very lightweight desktop, menu and panel so I guess you could call it a DE but it's all contained in one executable.
