eigenspaceWit, unker, Git: The lost medieval pronouns of English intimacy
https://www.bbc.com/future/article/20260408-the-extinct-english-words-for-just-the-two-of-us
English used to have dual pronouns (what the article is a about), proper accusatives and genitives (she/her/hers, who/whom and the apostrophe-s genitive are survivors), formal/informal 2nd person pronouns (you / thou) and quite a few other things that come up when you learn French or Latin.
Yes/No and Yea/Nay used to mean different things too: "Is this correct?" could be answered "Yea, it is correct" whereas "Is this not a mistake?" could be answered "Yes, it is correct" (which you can also parse by taking the 'not' literally).
"Courts martial" and "secretaries general" are examples where the original noun-first word order remains.
This sucks because yes its a mistake or no its not a mistake both fit
they don't fit, because 'yes' was not supposed to be used in the context of 'yes it is a mistake', yea was. Having two words helped stop that ambiguity.
It's confusing because it was stated wrongly.

Yes contradicts the negative question. So "Is this not a mistake?" should be contradicted with "yes, it is a mistake" or affirmed with "no, it is not a mistake".
It's further confusing because we have the idiom of suggesting things politely in a tentative manner such as isn't this a mistake? which has lost its sense of negativity and has come to mean "this is a mistake, I think," as opposed to being parsed literally to mean "this is not-a-mistake, I think".
