I'm just using the wording that's found in other parts of the manual. Not trying to be fancy here :)
Emacs manual:
"If an Emacs Lisp file is installed in the Emacs Lisp load path (defined below), you can load it by typing M-x load-library, instead of using M-x load-file."
My understanding is that "install in the load path" means put the file in a path that Emacs already knows vs "add the path to load path" means make Emacs know about that new path.

Thank you. Reading the manual did not help much here. But that's ok for now. I'm not interested in knowing all the subtelties of loading files.

Not that I can tell.

The Elisp Introduction seems to use "install" more as "be able to use the library" hence "load".

Not that I can tell. That's the reason why I'm adding this line to the manual. To make that explicit.

I'm pretty sure I don't know the difference.
