チャモロ語
Today, there is an ongoing issue on the Chamorro language orthography between NMI Chamorros and Guamanian Chamorros (example: Mt. Tapochau vs. Mt. Tapochao). As of 2021, the Guamanian Chamorros have come out with an official orthography for the Guamanian dialect, whereas the NMI Chamorros have yet to develop an official orthography. Rather, the NMI Chamorros spell their words based on how it sounds.
