platform — adjective

Synonym discussion

Sense: noun/2

For noun sense 2, platform is the everyday word for the raised place beside the rails where passengers wait and get on or off a train. Track is different: it names the line the train runs on, and in American usage the departure may be announced by track number instead of platform number. Station is the whole place, not the waiting edge itself. Concourse is the larger open area where people walk, buy tickets, or meet. Boarding area is broader and can also be used for buses, ferries, or planes. So you can wait on platform 4, check whether the train is coming into track 2, and meet your sister in the main station concourse.

Etymology

FrenchEnglish

English borrowed platform in the mid-1500s from French plateforme. In French, the word referred to a ground plan or flat form. The earliest English uses were about a level structure raised above the surrounding area. From that base idea, the word later widened to railway waiting areas, speaking stages, political positions that people stand on, and finally computer and online systems that serve as a base for other activity.
