Answer:
Barangay came from the word Balangay which is a huge wooden water vessel used by ancient Filipinos as a mode of transportation during pre colonial era. In each vessel a clan or a family is assembled and they live inside the balangay as they journey from island to island. Upon settling in to the land people are organized in groups so that head of the community or the Datu can easily manage them, also it is an efficient way of distinguishing people from other families these groups assemble as how they are formed in the balangay later the word changed to barangay, a well organized independent village.
