movement (n.)

late 14c., mevement, "change of position; passage from place to place," from Old French movement "movement, exercise; start, instigation" (Modern French mouvement), from Medieval Latin movimentum, from Latin movere "to move, set in motion" (from PIE root *meue- "to push away"). In the musical sense of "major division of a piece" it is attested from 1776; in the political/artistic/social sense of "course of acts and endeavors by a body of persons toward some specific end" is from 1828.
