I've heard it explained that "hey" used to be more of an urgent way to get someone's attention, rather than a casual "hello" like it is now, so it sounded rude to some older folks.
I'm glad the "not worth engaging with" attitude is dying out, but I do still think it's important to push for people to communicate accurately and effectively, which includes understanding and following grammatical rules when needed.
Language and vocabulary are essential to how we think and collectively problem-solve.
Yep, I get the "Language is constantly evolving" argument, but if I have to read your sentence three times just to parse it because you were too lazy to press a few keys, I'd consider that disrespectful to whomever is reading your comments
No seriously, I have no clue what you were talking about but it's very normal for any social group to develop a unique way of language that you have to learn when you want to engage. It's not as if farmers wouldn't use terms lay people don't understand
Everything I said is actually kinda sensible and as a sentence made sense. Obviously it uses too much slang at once and no one would make a sentence purely made of slang like that, but theoretically it's a valid sentence with modern slang.
I'm old as hell. I solely learned this just to mess with the young ones lmao.
But you make that decision based on social status not based on what the person is saying. If your manager wrote emails badly you would put in the effort to understand them. Not trying to pick on you, we all do this. My point it isn't really about correct vs incorrect it is our tolerance for the how much effort we are willing to put in to understand.
The point of language is to communicate information.
If the information was successfully relayed, the language exchange was successful.
If the person knows you MEAN "hello, I would like two of these items here, thank you good sir. hands cash and cashier says thank you You're welcome. Have a pleasant day, sir" when you SAY "Sup, two please. Thanks man. No problem have a good one." then you have successfully languaged.
So when my wife with a plethora of issues involving word recall says some insane thing because she can't remember the right words, as long as I understand what she means, her language did it's job.
There's descriptive and there's prescriptive linguistics. The first is the scientific endeavor of finding out and explaining how a language works. The second is the realm of anal politicians from the colonialist era who used language as an oppression tool to suppress local cultures and force the hegemonic culture upon indigenous people to make it easier to dominate, eradicate and subjugate them. Currently regarded as one of the defining elements of Genocides. For examples see, Spanish, French, English, Russian, German, Dutch, Portuguese, Mandarin … well you get the idea.
