English speakers, what's a not-fluency-related quirk/modification of the language that annoys you when you see it?
Yes yes, language changes over time. I've heard that mantra for decades and I know it. That doesn't mean there aren't language changes that aren't grating when they become fashionable (and hopefully temporary).
For me, "morals" being used as a crude catch-all application of "morality," "ethics," "integrity" or related concepts bothers me. Sentence example: "Maybe if society had morals there wouldn't be so many minorities in prison."
An even more annoying otherwise-fluent-speaker modification I see is when "conscious" is used to mean "consciousness" and "conscience" interchangeably. Sentence example: "Single mothers on welfare that steal baby formula have no conscious." It sounds like they're saying the shoplifter is not mentally aware of their own actions, not that they're lacking sufficient "morals" to let their baby starve for the sake of Rules-Based Order(tm).
There's others, but those two come up enough recently, with sufficient newness, for me to bring them up here. Some old classic language quirks are so established and entrenched that even though I hate them, bringing them up would likely invite some hatemail and maybe some mystery alt accounts also sending hatemail after that. You know, because they "could care less(sic)" about what I think.
Corpo-speak e-mails from bloviating, self-important middle managers who regurgitate such turns of phrase as "at this time" and/or "in a timely manor [sic]" make my eye twitch. I can overlook a lot of the "synergizing our thought leaders with operational tempo" jargon salad, but the aforementioned phrases trigger my fight-or-flight response, probably because they reek of petty tyrant small business night manager mentality and bring me back to the headspace of dealing with bosses like that when I was a kid.
I also once had to work with an IT project manager who insisted on pronouncing the word "processes" as if it had a long-E vowel sound in the plural ("pro-cess-eez"). It would derail my train of thought every fucking time.
Also also once had a direct supervisor who would throw around "irregardless" almost daily.
