Adams, Ilocos Norte in the context of "Ilocano language"

The barangay (/bɑːrɑːŋˈɡaɪ/; abbreviated as Brgy. or Bgy.), historically known as the barrio, is the smallest administrative division in the Philippines. Named after the precolonial polities of the same name, modern barangays are political subdivisions of cities and municipalities, and are analogous to villages, districts, neighborhoods, suburbs, or boroughs. The term barangay is derived from balangay, a type of boat used by Austronesian peoples when they migrated to the Philippines.

All cities, including independent cities, and municipalities in the Philippines are politically subdivided into barangays, with the exception of the municipalities of Adams in Ilocos Norte and Kalayaan in Palawan, each of which contains only one barangay. Barangays are sometimes informally subdivided into smaller areas called purok (English: "zone"), or barangay zones consisting of clusters of houses for organizational purposes, and sitios, which are territorial enclaves—usually rural—located far from the poblacion. As of January 2025, there are 42,011 barangays throughout the country.
