means The rate or speed at which something moves, happens, or is done — and, as a verb, to walk back and forth or to set the speed of an effort.

from From Latin passus, 'a step, a stride' — literally the stretch of ground covered between two footfalls. It walked into Old French as pas and then into English, keeping its measured, foot-by-foot logic: a 'pace' was once a unit of distance counted in strides, before it loosened into the more general sense of speed. The same Latin root paces quietly through 'passage' and 'pass.'
