Rufio:
It's one thing to say that all prescriptive grammar rules are wrong and another to say that they are not neccessarily accurate.
JTT: I don't know who said they're all wrong; it certainly 'twarn't me. There are a number of fine prescriptive rules for writing; use a period at the end of a sentence, etc, etc, etc.
But I must admit that I am finding it more than a bit difficult to imagine the crucial distinction between inaccurate and wrong.
---------------------------------
Rufio:
"Are" is a single surface structure which is used to represent several different meanings. One of them is the second person singular. It's not a plural verb, in that context.
JTT: "is" is a single surface structure which is used to represent several different meanings. One of them is the plural use. It's not a singular verb, in the context of words like everyone.
-------------------------------------------
Rufio:
And even if you would refer to "everyone" as "they" in a following sentence, you still wouldn't say "everyone are bringing their bikes".
JTT: You couldn't use in a following sentence, anything BUT a plural. That should clue you in to the ACTUAL meaning of words like everyone.
--------------------------------------
Rufio:
True, there is a difference between something being grammatically plural, and semantically plural. For example, take "pants". The fact that when we say "pants" we mean a singular thing does not change the fact that it is grammatically incorrect to use singular verbs with the word.
JTT: The gaps in your logic are astonishing, Ruffio. "are" clearly was/is a plural verb and it became accepted into use as the default verb with 'singular 'you'. If English can handle this type of adjustment, then there no reason to NOT make the same assumption about 'everyone', to wit, 'is' is not a singular verb in this case.
But why all the mental contortions. English simply makes use of that which is the most meaningful. It's a complete red herring that we don't switch to "everyone are". We don't simply because it's conventional to use 'is'.
And yes, Rufio you're right; notional plurality is much more important to speakers and meaningful language use than some old silly prescription. The long and successful use of they/their/them, dating back long before this errant rule was penned, clearly illustrates that.
--------------------------------------
Rufio:
And rules that are inaccurate now have not always been so. While I don't think that the destinction between "I" and "me" has only to do with case anymore, it did at one point.
JTT: I'm not so sure it did but that's moot. The 'rule' has long been nonsensical, perpetuated by those who simply repeated old saws.
Rufio:
Every bit of prescriptive grammar that is employed today has a root in the history of the language somewhere. It may need to change with the times, but it has not always been wrong.
JTT: Language science simply doesn't support that view, Rufio.

For here are the remarkable facts. Most of the prescriptive rules of the language mavens make no sense on any level. They are bits of folklore that originated for screwball reasons several hundred years ago and have perpetuated themselves ever since. For as long as they have existed, speakers have flouted them, spawning identical plaints about the imminent decline of the language century after century. All the best writers in English have been among the flagrant flouters. The rules conform neither to logic nor tradition, and if they were ever followed they would force writers into fuzzy, clumsy, wordy, ambiguous, incomprehensible prose, in which certain thoughts are not expressible at all. Indeed, most of the "ignorant errors" these rules are supposed to correct display an elegant logic and an acute sensitivity to the grammatical texture of the language, to which the mavens are oblivious.
