I was always taught by my teachers to never run in the corridors, but little did they know that they were etymologically incorrect. The word was borrowed in 1591 from French, and that was taken in the fifteenth century from Italian corridore, which primarily referred to a long passageway between separate buildings but more literally meant "runner", just like how in English we sometimes use the word runner to describe long things like vines and carpets. Corridore comes from the Latin verb correre, which meant "to run". That, through the Proto-Italic reconstruction korzo, traces to the Proto-Indo-European root kers, also "to run". This means that corridor is related to words like cargo, caricature, chariot, currency, discharge, excursion, intercourse, miscarry, precursor, and many other words that kers forms all or part of.
