Root Breakdown
Root-derivedpro- (forward) + pag (plant, fix) + -ate (verb) = 'to fix a plant slip forward into new soil' — the gardener's literal sense. English extended it to ideas (plant a rumor so it spreads) and to physics (a wave propagates through a medium). Always the picture of something planted that then spreads on its own.
