To move around quietly and carefully, often secretly, like a predator hunting; to wander around looking for something.
From Old French 'prouler' or Anglo-Norman 'proler,' possibly related to 'prol' meaning 'vagabond.' The word entered Middle English with connotations of stealthy movement.
Predators prowl, but so do detectives and suspicious people—the word captures that calculated, sneaky movement whether you're hunting prey or hunting for clues. It's the sound of stealth.
