Itza'[clarification needed — Is this an accented letter A, as in Lake Petén Itzá? If so, add Itzá as a name & correct all articles. If not, explain the apostrophe.] (also Itza or Itzaj) is one of the Yucatecan branch of the Mayan languages.
The other languages in the Yucatecan branch are Yucatec, Lakantun, and Mopan. All the Yucatecan languages are closely linked with each other. However, people speaking Itza' and those speaking Yucatec do have difficulties understanding each other.
