Other comments: Ivatan or Itbayaten has a decimal system. There are two forms of cardinal numbers from 2 to 10 in Itbayaten. The first one is used in series counting and counting things, the second for counting human beings. The Itbayaten used a particular way to express compound numbers 11 to 19, 21 to 29 ..., which means 'one at the 2nd stage or step'. Nowadays, the numbers after ten have been replaced by Spanish numbers.

The Ivatan (Ibatan) language, also known as Chirin nu Ibatan ("language of the Ivatan people"), is a Philippine language of Austronesian origins spoken in the Batanes Islands of the Philippines by approximately 33,000 speakers. Although the islands are closer to Taiwan than to Luzon, it is not one of the Formosan languages. Ivatan is one of the Batanic languages, which are perhaps a primary branch of the Malayo-Polynesian family of Austronesian languages. The language of Babuyan Island is sometimes classified as a dialect. Most of the Babuyan population moved to Batan Island and the Luzon mainland during the Spanish colonial period. The island became repopulated at the end of the 19th century with families from Batan, most of them speakers of one of the Ivatan dialects.
