A vocabulary of Igorot language as spoken by Bontok Igorots

Published by the Bureau of Printing in Manila in 1908, this vocabulary was authored by the Reverend Walter Clayton Clapp, an Episcopal missionary stationed in the Mountain Province of the Philippines. During the American colonial period, the United States government prioritized the linguistic documentation of indigenous groups to facilitate governance, education, and missionary work among the Bontok Igorot people.

The design of the work reflects the clinical, administrative style typical of early twentieth-century colonial ethnographic publications. Clapp aimed to create a practical linguistic resource for outsiders interacting with the Bontoc population, focusing on phonetic consistency and basic translation. While it served its purpose as a foundational reference for linguists and colonial officials at the time, it remains a significant, if complex, historical artifact of the American administrative encounter with the cultures of Northern Luzon.
