Inagta Alabat (Alabat Island Agta) and Ayta Kadi are the same language, though the term "Ayta Kadi" is the name recognized by the Komisyon ng Wikang Filipino (Commission on the Filipino Language). The term "Inagta Alabat" refers to the language of the Agta people who live in the Alabat Island and neighboring areas of Quezon province. Ayta Kadi is the language spoken by the Ayta Kadi group living in the towns of Alabat, Catanauan, and Lopez in the province of Quezon; and in Barangay Putingkahoy in the town of Rosario in the province of Batangas. Since Tagalog is the lingua franca in Quezon, it is also the language spoken more by the Áyta Kadí than their native language. In fact, most Áyta Kadí youth have not learned their language and have instead become accustomed to using Tagalog (Filipino) and English, which are the languages of instruction in school.
UNESCO classified the language as "
critically endangered". Inagta Alabat forms a subgroup with
Manide. The extinct
Katabangan may have also been related. ==Lexicon==
