"to remove impediments to the movement or progress of, accelerate the motion or progress of, hasten, quicken," 1610s, from Latin expeditus, past participle of expedire "extricate, disengage, liberate; procure, make ready, put in order, make fit, prepare; explain, make clear," literally "free the feet from fetters," hence to liberate from difficulties, from ex "out" (see ex-) + *pedis "fetter, chain for the feet," related to pes (genitive pedis) "foot" (from PIE root *ped- "foot"). Compare Greek pede "fetter." Related: Expedited; expediting.
