"No hea mai ʻoe? is what I heard in my young days." Iʻm guessing No hea ʻoe? as taught in duolingo is easier to start with. Down the road the use of mai/aku will find itʻs way into the lesson plan. Hawaiian isnʻt that easy IMO.

No - From/of Hea - Where 'Oe - You

Translates to

"Where are you from?"

Please correct me if I am wrong.
