It’s pretty common for groups of people to have domain-specific language.

I’ve done programming on and off for years. Recently I’ve seen the term “closure/clojure” in various places. Context is no help on the meaning. If it matter’s I’ll just have to look it up. Another term that comes up if “Turing complete” and there are large arguments about whether X is turning complete or not. I’m sure that it means something to those using it but it has no meaning to someone who is not in the know.

I don’t point this out to shame anyone. It’s just a natural process that happens within a specialize knowledge space that needs it’s own terms to define concepts.
