I always believed a Diphthong was just a combo of 2 vowels, for all I know it has nothing to do with a different pronunciation, you just combine the 2 written vowels into one sound. A lot of on-line sources back me up on this, as I quote:
"A diphthong (pronounced /ˈdɪfθɒŋ/ or /ˈdɪpθɒŋ/;[1] from Greek δίφθογγος, diphthongos, literally "two sounds" or "two tones"), also known as a gliding vowel, refers to two adjacent vowel sounds occurring within the same syllable. Technically, a diphthong is a vowel with two different targets: That is, the tongue moves during the pronunciation of the vowel. In most dialects of English, the words eye, hay, boy, low, and cow contain diphthongs."
Secondly, all info I get while googling for ANCIENT GREEK (not talking about modern-day Greek) claims "οι" should sound like "oi" in the English word coin.
Most languages have evolved a LOT over the years (try reading archaic German or English, for instance!), so it wouldn't surprise me. And I spoke with two people who have studied ancient Greek in their time, showed them the Turisas CD and asked them about the title, they both read it as something between "oi" and "ai" but surely not "ee".
My question is, Crucifier, have you actually studied ancient Greek? or are you purely basing your opinion on modern-day Greek?
