That's kind of my opinion about it. If people want to speak to me in a dialect or with a lot of slang, it isn't an issue until I can't understand them. And at that point, it's not really a 'bad' thing, just a communication hurdle to overcome.Skippy wrote:People can speak however they want, and it really doesn't bother me as long as I understand what they're talking about. But if you want to communicate through writing, then you have to follow some basic rules, or your message will be unclear or even possibly the opposite of what you intended.
However, writing is a different ballpark. I feel that, especially in academia, there is a need for rules and style in order for papers, books, presentations to be consistent. It's why having a lingua franca is a good idea on paper (and for the record, I'm in favor of making the scientific lingua franca "Latino sine flexione", that way, there's no "it's my native language, therefore, I'm better than you" thing going on). When two people are writing about the same topic, but the spelling, grammar, and punctuation are all over the place, it's hard to understand (easily!) what's going on. Having prescriptivist rules makes things easier for something like that.
In general, however, yeah, I get that languages change and that dialects, culture groups, and even socio-economic classes speak differently. But there are a lot of "correct" usages that I think everyone might have trouble with. But if, in writing, it helps maintain ease of reading, understandability, and consistency, I don't see it as an issue.
Now to jump on the linguistics train. A spooky thing about linguistics is that it's provided solid evidence that grammatical rules are actually inherent in the human brain. [I'm probably going to procede and present a very shallow and uninformed discussion of this, though] For instance, children whose parents grow up speaking a pidgin language will take what they know and actually add rules to it--even without prompting to do so, or even explanation on what constitutes "good" grammar--creating creoles. It's hard to explain.Skippy wrote:They have to be organized by someone. They have to be agreed upon by some group of people. That's how rules work.
You mean from birth? Or am I misunderstanding you?
Basically, the nature of true grammar is still kind of a mystery. But it's actually a system that no one really agrees upon (initially, at least). It just comes into being (again, I'm doing a really bad job at explaining this).
Are there any linguists out there who can explain it better than I just tried?

Spooky.
