Instead of using "the", Hawaiian uses context and the placement of words within a sentence to convey definiteness.
For example:
* "The book" in English could be translated as "ka puke" in Hawaiian.
* "The house" in English could be translated as "ka hale" in Hawaiian.
The use of "ka" before the noun is what indicates that the noun is definite (meaning it is a specific book or house).
So, "the" in Hawaiian is implied through context and the use of "ka" or other grammatical markers.
