"She is a tall student."

Translation: He haumāna lōʻihi ʻo ia.

[OdellHubba]

I still having some confusion between o and 'o.

[KiUlv]

O is often like"of" but 'o comes before a proper name or pronoun

Hale o kona -- house if kona
Hale 'o kona-- kona house (the name of the house is kona)

[wanderingpup]

Do most adjectives go after nouns, and what is the role of "he" in sentences like this?

[AlanAbonyi]

Modifiers almost always follow the subject. Itʻs best not to use conventional parts of speech to describe Hawaiian because any given word can often be used as a noun, verb, adjective or adverb.

he = a/an

he haumāna = a student

ka haumāna = the student

nā haumāna = the students

[valinor3579]

Sometimes itʻs written like: Lo'ihi haumāna ʻo ia. (Is tall student she). I wrote it like that but it was wrong. So it has to be: Is student tall she? I thought with adjectives they're often at the start...
