Because of over a century of American influence, many Chamorros think of the English letter I when they hear the Chamorro sound AI. As in "island, ice, iron."
So they spell GUAIYA, the Chamorro word for "to love," as GUIYA.
This creates confusion because there already is a Chamorro word GUIYA, and it means "he, she or it."
Watch the video.
So, to spell "I love you" in Chamorro, it is : HU GUAIYA HAO.
GUIYA means "he, she or it."
