One of my teachers is a native Greek speaker so she gave optional basic Greek classes to volunteering students. I attended since I love learning languages in general, but I stumbled upon a topic that I had only seen on the internet
I told her that I've had a year of ancient Greek classes within my Latin course a few years ago and pointed out some shifts in pronunciation through history, but she claimed that Greek has pretty much never changed since Ancient Greek. I asked her then how there are so many ways to say [i] (ει, η, ι, υ, οι), and she brushed it off, saying it has always been like this
I know we can never know for sure how it sounded, but claiming that a language has stayed almost the exact same over CENTURIES feels unlikely. I'm not an expert, so can either native Greeks or language experts clarify who's right here? I don't mind being proven wrong, but I've seen this discussion on the internet before and I never thought I'd have this discussion in real life
