robber

Century Dictionary and Cyclopedia

1. n. One who robs; one who commits a robbery; in a looser sense, one who takes that to which he has no right; one who steals, plunders, or strips by violence and wrong.
2. n. Synonyms Robber, Thief, Pilferer, Freebooter, Marauder, Brigand, Bandit, Pirate, depredator, despoiler, rifler, highwayman, footpad. (See pillage, n.) A thief takes other people's property without their knowledge; a robber takes it openly, whether or not resistance is offered: in a looser sense, thief is often applied to one who takes a small amount, and robber to one who takes a large amount. A pilferer takes very small amounts by stealth. A freebooter and a marauder rove about, robbing and plundering: the word freebooter emphasizes the fact that the man helps himself at his pleasure, while marauder suggests the loss, inconvenience, fright, or distress produced. A brigand or bandit is one of an organized band of outlaws and robbers, especially in certain countries long known as infested with such bands; bandit is rather a poetic or elevated word; brigand is more common in prose. A pirate is a brigand of the sea. All these words have considerable extension by metonymy or hyperbole.
3. n. In bee-keeping, a boo which takes honey from a strange hive.
