Demotic

 "Language of the People"
As expected, it's shit. https://en.wikipedia.org/w/index.php?title=Demotic_Greek&oldid=1170059582

 "Syntactically, it favors parataxis* over subordination. It also heavily employs redundancy, such as μικρό κοριτσάκι (small little-girl) and ξανακοιμήθηκε πάλι (he-went-back-to-sleep again). Somewhat in connection with this, Demotic employs the diminutive with great frequency,"
 *(is a literary technique, in writing or speaking, that favors short, simple sentences, without conjunctions)

 Redundant diminutives? It's baby talk. "I went to the toilet and took a wee-wee in the toilet." Nice declaration against interest. Did you stub your toesies and hurt them?

 Since 1976 this baby talk has been the State language of the Greek government. They Officially never go beyond babby's first Greek.


 Like everything else, languages are property.
Commons are tragic. Unsecured property suffers vandalism and decay.
Languages need specific responsible owners performing maintenance and excommunicating foreign speakers, especially locally-born foreign speakers.

 Unowned languages corrupt.
Specifically exhalting the vulgate or demotic makes it go faster, though. 

 Anyway, time for some early-onset curmudgeonry.

 Naturally we can see the same thing happening to English, except it includes the big-words-they-don't-quite-get trope too. Little men like to use big words because they think it makes them sound grown up. It doesn't, in part because they use it wrong. "This corporation traversed to the commode, meanwhile excreting upon egressing into the commode." ("You sound so smart! But why not just actually instead?")

 Moderns deal with this in part by using such generic words that they apply to everything and can't be used wrong. "Content." "What was the entertainment content of the content?"

 Eventually their tiny minds can't handle the broad abstract and it becomes specific, and not coincidentally makes them sound even dumber.
Retard merely means to slow. Only retards think it refers only to mental retardation.
Intercourse is a course that's interlinked. Not specifically sexual intercourse. Children shouldn't be talking about that stuff anyway - are you hanging around a groomer? Oh what, your hobby is horseriding? *record scratch* You keep a long-haired cat?
Dumb simply means can't speak...
"There were multiple..." so, two? "No there were a number" zero is a number.
"I have lots of resource." Oh my god kill me or kill yourself.
At least the only thing wrong with moron is that a moron came up with it - he thought being stupid could be morally neutral.  

 Demotic = Demonic. That's not a language evolution thing, that's an empirical thing. It's rough out there for literates who know what words mean.
