Similarly, “dinosaur” is pronounced dino-sour, and not as dino-saw.
In ancient Greek, as best we can tell. The “i” is more like “ee” as well. In English, it’s “die-no-sore” unless you’re non-rhotic, and if you are, then piss off, you posh ponce.
In English, it’s a matter of honor to mangle foreign loan words, unless you’re the kind of twit who pedantically pronounces foreign words as though you’re not speaking English, but the language of origin. That’s most common with French loanwords, since French was once considered higher-prestige than English. But I’ve even heard people attempting to pronounce Arabic words like that, despite having no idea of Arabic phonology or case inflection, with ridiculous results.
There are no Greek C’s. With Greek loanwords into Latin, “k” was mapped to Latin “c.” Then the pronunciation of “c” diverged, with the Catholic Church adopting the Italianate pronunciation of the letter “c” in the Middle Ages, which was not the preferred pronunciation in classical Latin. We know how Latin was pronounced because the Romans actually wrote guidebooks for newly-assimilated Romans on how to speak proper Latin. That’s also how we know that “r” was trilled or rolled-- the guidance was “make it sound like a dog growling.”
Even English has wide variations in how diphthongs are pronounced. I’m living in southwestern England, and the old boys pronounce the sounds in diphthongs almost separately: “boy” is two syllables: “bwooey.” But like regional dialects everywhere, that’s fading in the younger generation.
I see that your dialect pronounces “pen” and “pin” the same. Midwestern US?
The third way would be a difference in how the diphthong is pronounced: “-aur” or “-ower.”
Me too. I’m not a pedantic Latin-pronouncer who’d say “ken-tower”
