May I offer a 'tail-piece' to the dialogue on 'If I were' and 'Wish I were'?
Remember: "If wishes were horses... beggars would ride."
This doesn't necessarily mean beggars can't or won't ride. This is just a figure of speech of course.
Now look at this: If I were king... I would make you my Queen (says ...đ to...đł)
This means he INTENDS to do it, though it hasn't happened yet. So, not necessarily something that can't be, that is impossible.
Whatever meaning is contained in a sentence, if one uses IF with the past tense of TO BE, in singular, it HAS to go with 'were'.
Same for 'Wish' as a verb, as in: Wish I were wrong; Wish he were back soon (uh? who?...đ)
So, all you folks were (the other 'were') right ... in a way đ
