As you've pointed out, there's not a lot of consistency.
I say:
formal authorities, whether human or in print, struggle to explain
informal usage, much less regulate it.
Even the French and Spanish, with their language academies, can only regulate the language in documents produced by the government and the more prestigious institutions who choose to abide by the rules. Slang and foreign words are rampant in colloquial speech and the popular press.
Oddly, the Germans, whose academy's power has dwindled to the regulation of spelling and punctuation since the Third Reich collapsed, are considerably more careful about adopting neologisms and foreign words than the French- and Spanish-speaking people. They still say
Fernsprecher ("distance-talker") and
Kraftwagen ("powered vehicle") instead of "telephone" and "automobile" like most of the rest of Europe.
We will define rape as forced sex, but that only involves sex. If there is violence added to the rape sex, instead of calling this a brutal rape, to make it sound worse, we will call it an affair. We all know the term affair, means sex and violence, but the word itself sounds so innocent. This creates calculated confusion and helps to lead people astray.
Huh??? What country do you live in? In the USA, "rape" is forced sex, whether the force is psychological, physical, or chemical. No one here refers to a rape as "an affair." Despite my earlier attempt at a definition of "affair," the one thing that all affairs have in common is
mutual consent.
BTW, I forgot that back in the Bronze Age when I was growing up (a process I never completed), the usual term was "love affair." In those days "love" was often used (very confusingly) as a euphemism for "sex," a word that was seldom heard except to mean "gender." A child born out of wedlock was called a
love child.
A modern example of this tactic is calling the most expensive healthcare scenario, the affordable care act, to create an image separate from the reality.
Having spent most of my life in government service, I can assure you that the ACA is indeed supposed to be affordable for the
citizens, if not for the
government. In aggregate, it's supposed to reduce the total cost of health care in
the U.S. economy. Whether it will work out that way remains to be seen, but based on the government's performance since Reagan added a new zero to the national debt (a president who miraculously is still regarded as "conservative"), it's obviously unlikely.
Someone in linguistics may have a clear head in terms of label versus reality, but the goal is to manipulate the herd who does not know they are being gamed.
Yes, we've all read
1984. Orwell tried to make the point that the populace falls for these tricks, but in reality we're a lot harder to fool than the people who populate his book. Especially after a large segment of the planet's population have already experienced the linguistic machinations of the USSR, the Third Reich and the PRC. Even the U.S. government after the Generation Gap, although it's hardly in a class with those other offenders.
Lying is called spin, which sounds like something a child playfully does to get dizzy.
"Spin" is not outright
lying. Everyone presumes that the people they're talking to are smart enough to catch it. Spin is the imposition of
bias, such as presenting examples of a phenomenon that seem to illustrate your point. Yet you must also present at least a few that contradict you or your audience will, indeed, see that you are probably lying.
But the liberal word play will add worse sounding buzz words to manipulate emotions, so most liberals assume the other way around is real. They will not check the reality data.
Conservatives are just as clever at this game. After all, it is they who redefined the anti-abortion movement as "pro-life," even though refusal to perform an abortion, in some cases, will kill the mother; and the pro-abortion movement as "pro-choice," even though the fetus is not given a choice.
I would think linguists would act like the police to set the record straight in terms of this word game.
Linguists are human too. They differ politically from one another as much as any other demographic.
