Pronounced like "buy-uh-nee-hun," bayanihan is a Filipino word derived from the word bayan meaning town, nation, or community in general. "Bayanihan" literally means, "being a bayan," and is thus used to refer to a spirit of communal unity and cooperation.
Although bayanihan can manifest itself in many forms, it is probably most clearly and impressively displayed in the old tradition of neighbors helping a relocating family by getting enough volunteers to carry the whole house, and literally moving it to its new location. They do this by placing long bamboo poles length-wise and cross-wise under the house (traditional Filipino houses were built on stilts), and then carrying the house using this bamboo frame. It takes a fairly large number of people -- often 20 or more -- working together to carry the entire house. All this is done in a happy and festive mood. At the end of the day, the moving family expresses their gratitude by hosting a small fiesta for everyone.
