Sorry, not exactly about history, but I figure people interested in history might know the answer.
Right. I'm not going to actually write with greek letters, but I hope you understand the transliteration.
I know that the ancient diphtongs ai and oi becomes flat e and i respectively. for example, Toxotai is pronounced Toxote, and athanatoi is athanati in modern greek.
diphtong ei also becomes i. But I wonder, what happens in words like Kyrenaioi or Athenaioi? following the sound change rules, it should become kirinei and athinei respectively. aioi has now become ei. My question is, does this ei further simplify to just i? Or are the sounds pronounced separately? or is it a diphtong?
How is Kyrinaioi pronounced in modern greek? Is it kee-ree-neh-ee (without a diphtong)? Is it kee-ree-nee (ei made into i)? Or is it kee-ree-nay (with diphtong)?
