I think that you may find that "The Internet" is a particular instantiation of an internet, an internet being a network that does not require all nodes within the network, to use the same operating system - I think, from memory, IBM was the first to introduce an "internet operating system"; SNA, which allowed inter-operating system communications, so that a VAX running VAX-VMS could communicate with a VAX running BSD UNIX could communicate with a computer running SCO UNIX could communicate with a DEC PDP-11 running RSTS/e could copmmunicate with an IBM 3081 running whatever particular operating system would be running on it, could communicate with a SPERRY UNVAC running whatever operating system running on it, etc...

After SNA was established, from memory, DEC put out its equivalent; DNA (DEC Network Architecture), and then other organisations followed suit, with other internet architectures, of which "The Internet" is only one (albeit the now primary) instantiation.

A WAN, being a Wide Area Network, as (in that alone) you correctly stated, which is a network, usually involvinmg only a singular operating system for it and its nodes, usually run by an entity like a medium to large business or government department, and is closed, so that it is only accessible by authorised people within the particular organisation. A WAN is a geographic classification for a computer network, and is relative to a LAN; a LAN may be limited to be being within a single building, or, may (?) extend beyond the building. A WAN usually extends across a large(-ish) city, and may extend between cities, states, or countries.

An example of a WAN, is the network that had (some years ago) been used by the Australian federal Department of Social Security (DSS), that had connected the DSS offices at different locations within the various localities (regional and suburban offices) within Australia, and, between the states and territories (almost states) of Australia.

A company such as BHP or BP, may each have its own WAN, connecting offices and presences around the world, each operating as a closed network.

And, a WAN may or may not be an internet.

But, WAN != "The Internet".

"The Internet" is an instantion of a WAN, and, is an instantiation of an Internet.

A LAN could be an internet, especially, as, here, we have a LAN that includes MS Windows, Android, Linux, and, hopefully, soon, an instantiation of a BSD system, computers.

So, WAN != "The Internet" (which is the term that is sometimes used by the confused, to refer to "The World Wide Web", which runs on top of "The Internet").

When terms are misused, especially on a list such as this, which includes (I believe) readers of various levels of knowledge, from almost "computer illiterate", to "experts", it aggravates the confusion, and, aggravates problems of communication between people of varying levels of proficiency regarding the English language.
