I think so. That seems to be the rule so far, for example in the sentence I saw previously: "Aia ʻo Kaʻiulani i hea?" - "There is Ka'iulani in where?" - "Where is Ka'iulani?". It'd be good to get a more detailed explanation though, as I don't fully understand it either.
Can someone please clarify the pronunciation of "aia". The spoken is so fast it's hard to tell but to me it sounds like he's just say "A" (as in the letter in English) but that letter seems to be pronounced "ah" (like what you say to the doctor with your tongue out) in the words "ma" and "ka". Do Hawaiian letters change sounds? Clearly i need help! Thanks in advance.
