boarding

Boarding is a term with several related meanings. It generally refers to the act of entering or loading onto a vehicle or vessel, or the process of providing temporary residence or protection using boards. In transportation, boarding describes the process by which passengers enter an aircraft, train, bus, ship, or other mode of transport before departure. It typically follows ticketing and security checks and is organized in groups or zones.

In education and housing, boarding denotes living on-site at an institution, such as a boarding school, college, or hospital ward. A boarding arrangement includes lodging and meals, with supervision and activities; students live on campus for a portion or full term. Boarding contrasts with day attendance and other non-residential programs.

In construction or emergency management, boarding means covering openings with boards, for security, weatherproofing, or temporary repair, as in boarding up a broken window or door after a storm or break-in.

In sports, boarding is a penalty in ice hockey and some other contact sports, for forcefully causing an opponent to be thrown or pushed into the boards surrounding the playing surface, potentially causing injury; penalties vary by league and can include fines or suspensions.

In maritime contexts, boarding can refer to approaching and entering a ship, either for inspection, boarding the vessel by authorities, or seizing the ship during hostilities; the term "boarding party" describes the team performing the act.
