Gonna go ahead and drop this knowledge for folks: Singular "They" is older than the pronoun "You" or the article "The".
"They" comes from Old Norse-Germanic. "Sa". "Sa" was gender neutral and referred to one or many people. It became "They" in Old English, that is to say: English old enough that Shakespeare would've been like "Thy speech is most strange 'pon mine ear. Whither came thy mother and thy father?"
Along with "They" came Their, Them, That, and The. That's right. THE came from Sa. Again, this is -OLD- English, which was really more German than English as you'd recognize it, today.
Remember that "Thy" from Shakespeare? Thy became super common in use because the nordic Thin (Pronounced Thine) meant "Yours". And that became "Thou" which eventually became "You". And it only became "You" because the nordic letter "Thorn" was pronounced "Th" and looked a lot like a Y as time when on. It started
þ and ended up
. It's also why "Ye Olde Blacksmiths Shop" is a thing. The "Ye" is actually "The" but people mistook the Thorn for a Y.
"They" as a pronoun, singular and plural, is older than "You" as a pronoun. Ain't that somethin'?
And if you want something -confusing- in english, let's talk about NOSACOMP.
Number, opinion, size, condition, age, shape, color, origin, material, purpose. That is the appropriate english order for stacking adjectives. It's something practically no person learns in American or English elementary school, but we all somehow -know-. And the second someone gets the order wrong the dissonance hurts our brains.
