The Military Police are frequently asked what is the meaning of "PROVOST"

The Middle English word provost is derived from the Old English word praefost and the Old French word provost.

These are both from Medieval Latin propositus, praepositus, which in turn is derived from the Latin praepositus "(one) placed before (others), from the past participle of praeponere, to place before or over .
