Etymology

Origin of platform

First recorded in 1540–50; earlier platte forme, from Middle French: literally, “flat form, plane figure”; see plate ¹, form

Explanation

A platform is any raised surface you can stand on, like the platform beside subway tracks where you wait for the train to arrive. When you're standing on something that's higher than the surrounding area, you can call it a platform, like a train platform or a viewing platform at a historic site. A platform is also the official stance of a politician or a political group, like a platform of improving public education. Also, there is the footwear known as a platform shoe, which has a very thick sole which makes the wearer appear taller, like standing on a platform.
