Synonym Usage

Lurk, skulk, sneak, prowl suggest avoiding observation, often because of a sinister purpose. To lurk is to lie in wait for someone or to hide about a place, often without motion, for periods of time. Skulk suggests cowardliness and stealth of movement. Sneak emphasizes the attempt to avoid being seen. It has connotations of slinking and of an abject meanness of manner, whether there exists a sinister intent or the desire to avoid punishment for some misdeed. Prowl implies the definite purpose of seeking for prey; it suggests continuous action in roaming or wandering, slowly and quietly but watchfully, as a cat that is hunting mice.
