"Kaʻiulani bakes bread."
Translation:Puhi palaoa ʻo Kaʻiulani.
A little answer is here: https://forum.duolingo.com/comment/33357137?comment_id=37635076 'They are using the direct objects as adverbs to modify the verbs directly.' (Lee (kelii....)) . Another examples: E ho'olilo kālā / e ho'olilo i ke kālā; E kahi lauoho / E kahi i ka lauoho; etc.
It would have to be 'Puhi ka palaoa i ke Ka'iulani'.
Best thing to do is research outside of DL. So much missing. Still a good place to learn, but you should always expand your pools of knowledge.
Pono on here isn't fully explained and is shown as meaning 'good'. It means, right, just, good, upright, moral, etc.
Sometimes I'll try another English word for a sentence and see if it works.
E wehe i ka puka.
Open the door.
But puka is more closely translated as 'hole'. I put,
'Open the hole', it worked.
Sometimes doesn't work for other words.
