is it pronounced like an (American) English speaker would pronounce those syllables? KEE-ah OR-ah? do I need to do anything specific with the R?
I’m just gonna direct you to the Māori dictionary and its example, this radio interview on Māori pronunciation, and this page of common greetings with recordings of their pronunciation, but I would write it as something like “kyaAWErah”. “R” in Māori is…IDK the technical linguistic terms, but sort of halfway to a “l” sound, much like in Japanese. It’s distinctly different from most English versions of “r”.
(I mean, nobody’s gonna misunderstand you if you say “KEE-ah OR-ah”, but you will 100% sound like an American/Australian/older or not trying very hard Pākehā.)
