In Hawaiian, iā is used as object marker before a pronoun or proper noun, while i is used before common nouns. Iā is also used before wai (whom). If the object is "me", i is contracted with the pronoun to iaʻu.
Both the direct and the indirect object take i or iā. The direct object generally precedes the indirect object as in English where there is a preposition before the indirect object:
