The word "train" originates from the Old French trainer (to drag, pull), derived from Latin trahere (to draw, pull). Initially, it referred to the act of dragging or trailing (e.g., a gown's train). By the 14th century, it evolved to describe a procession or retinue (people "drawn along"), later narrowing to its modern railway sense (vehicles "pulled" by an engine). The verb sense (to instruct) metaphorically extends from "guiding or directing movement."
