Alighting is an action of getting off or down from a vehicle, such as a bus or train, or any elevated platform. The word "disembark" can be used as a synonym for alighting and means to exit a vehicle or aircraft. Another synonym is "dismount," a term used mostly for horses or bicycles. "Debarking" can also be used in contexts like ships and cruises, where the passengers disembark. Other synonyms for alighting include "detrain," "deplane," "unload," and "eject." All these words share the same basic meaning of getting off a vehicle or platform, but they differ based on specific contexts.
