Now the really puzzling question is: How would someone learn about this particular saying without seeing it in writing? Are there actually people still using "hear hear" in everyday speech?
I've learned German, too. German is 'difficult', not because of its grammar, but because how mistakes are handled. Which is often with harsh commentary, ridicule or confusion. Not sure why that is the case, but English speakers are often kinder when offering corrections!
I'm going to give you the benefit of the doubt and assume that was a clever and subtle joke.
And it's been a while since I was a student. Cut me some slack :p
And I know I should've written 'i have' instead of 'i've' - in Arabic we say 'ill efforts blacken the face'
Joking aside, I think it's a consequence of English being a very complicated language with all sorts of borrowing from different language families. There's almost no such thing as "correct" English, and attempts to reason about it in a prescriptive rather than descriptive manner will almost certainly fail. Whether that's a good or bad thing is up for debate, but mistakes happen either way, and I reckon the average English speaker to be a bit more cognizant of that, recognizing that nobody - oneself included - really has a perfect understanding of the English language.
1 A cash register (noun)
2 In very poorly constructed resumes
3 In the farming sense (verb)
4 In internet forums alongside poorly written English
5 Shakespeare and other literature from several centuries ago.
So my advice: unless you're a time traveller, use "until".
I think I even forgot the difference between conjuncts and adjuncts, too. Grammar 1/2/3 were tough courses.
I'm leagues below the level of a native speaker, I'll admit that! But I did still do a ton of reading, which did improve my English, but won't protect against common pitfalls :P it could've been worse. At least I don't make those "your" "you're" mistakes, too often :D
