"Awi" is sort of a non formal way of saying uncle in Enga.

Lots of  times it is used by little kids to refer to their uncles or vice-versa. Other people in PNG refer to an Engan as an "Awi". I'm not really sure how that came about.  

Adults use the word "apange" which is uncle in Enga. In the Engan vocabulary there are not words for niece and nephew so both paties use the words apange(uncle) and arange(aunty).
