Is there a rule that tells you when to use upsilon vs ita or yiota (υ, η, ι) ?
It is widely used, but it is wrong. The correct form is μπίρα. Since it comes from European languages that never used a letter like y or similar.
It is time to change the orthography of the word, nobody knows why υ here.
True, the correct, new, simplified spelling of the word is with a "ι", but formerly it was written with "υ", that's why so many people (including me) still misspell it (even though I know it's wrong - old habits die hard). But what was on the mind of the person who decided to translate as "μπύρα" the "bier" (it's believed that the translation came from the German word) is a true mystery. I mean, I know that a theory this was based on is that the spelling of the loan should reflect the original word's spelling, so since there's not only an "i" but an "ie", the "ι" wouldn't be enough to reflect that, but how on earth was the "υ" a better option?! Anyway, I guess that one of the mysteries of the Greek language will remain unsolved for now :P
It says pino but it's just the strange TTS (text to speech) that sounds weird.
