My question has nothing to do with what we are learning right now, just out of curiosity.
The word na'aukake looks like it already comes with the plural article attached.
What other meaning is/are there for the syllable "na"?
Naʻaukake is a combination of a Hawaiian word (naʻau = intestines) and the word "sausage" borrowed from English (kake). So "na" cannot be separated from "naʻau," and since "sausage" is not a native Hawaiian food, the word "naʻaukake" was coined to try to describe it.
