On a recent trip to Luta, I learned the following words in casual conversation. These words are heard either mainly or exclusively in Luta. Some are Spanish, some are Chamorro.
Malahente. Something of a trouble-maker, disobedient, rebellious, discourteous. What we would also call disatento. The word is Spanish, "mala gente," "bad person."
Tammong. Big, as in dångkulo.
Fasisa. Same as tammong, dångkulo. Big!
Po'yet. Pee-wee. Small.
Hatgo. To go into the jungle looking for dågo, nika, fadang (foods) and so forth.
