The students walked down the corridor to their classrooms.
Corridor is derived from the Latin word "corridor" (meaning a place to run), which comes from "currere" (meaning to run). The term originally referred to a passageway or a place where one could run through.
Imagine a place where people can 'run' ('currere') through — that's why a corridor is a passageway.
