There's a really big debate that's still really to be worked through by the left I think about the differences between personal, modern collective, historic collective and scientific meanings for the same word, and how it's all addressed, particularly when not in progressive settings. For example the word moron:
- Etymology: From the Greek, meaning "foolish"
- Scientific root: Edwardian/Georgian term denoting an adult with a mental age of 8-12 (now replaced by "intellectually disabled")
- Historic collective: Mentally slow
- Modern collective: Anything from mentally slow to missing a point or doing/saying something foolish (not necessarily meaning the person is intellectually disabled)
Trouble is people can be personally using it with any shading of the meanings above. Thinking back I've used it to denote pretty much everything
except its scientific root before now. When I was younger I used it to sneer at someone who I thought was my intellectual inferior, and while I rarely use it today it slips in once in a while to mean "acting foolishly" or "saying something particularly poorly considered." As a trying-to-make-the-effort progressive I would certainly never dream of using it in its original meaning, but in its far more fragmented
social meaning there's a lot of de facto wiggle room.
Question is, can/will that fragmented usage be pushed out entirely, with "moron" banished to the realms of unacceptability, or does it, like other words of its ilk, slowly evolve away from its original meaning? "Foolish" is in fact a good example of a word which starts with one meaning (an entertainer) and ends with another (someone impractical, silly, lacking substance). "Stupid" comes from the word "stupefied" but is broadly used to mean everything up to and including intellectually disabled. There's few insults which aren't in some way comparative, but most end up as words with little meaning other than a vague expression of disgust, anger, or disapproval - no-one's actually thinking of donkeys when they call somebody an ass, or sex when they call someone a motherfucker. Alternatives to "I don't like you/what you're doing" with a good mouth feel for the sake of variety.
Humans have personal interpretations of every word they use, with communication essentially being a process of attempting to line up each others' internal conceptualisations. Sometimes, particularly in any circumstance involving aggression, fear, defensiveness, doing so becomes fraught. Even harder is the situation where someone uses an expression one way in the heat of the moment - "don't do that you fucking moron" meaning "I'm worried about your safety if you continue doing this thing which I know to be dangerous, and which you
should know is dangerous" but is then told off by someone seeing it a different way in which it means "don't do that, person whose foolish actions I will now for no good reason link to the intellectually disabled." Especially when, to the person saying "don't do that you fucking moron," the
real meaning, their intended meaning, seems blindingly obvious and is generally accepted as such in their own circles.
Which is a bit of a meandering way I guess of saying it's not easy, this language navigation lark, and it's deeply contextual both socially and personally. Just something to try and bear in mind when discussing it - everyone can be meaning the best, while sounding to each other like we're not.
