Robbery is the crime of taking or attempting to take something of value by force or threat of force or by putting the victim in fear. At common law, robbery is defined as taking the property of another, with the intent to permanently deprive the person of that property, by means of force or fear. Precise definitions of the offence may vary between jurisdictions. Robbery differs from simple theft in its use of violence and intimidation.
The word "rob" came via French from Late Latin words (e.g. deraubare) of Germanic origin, from Common Germanic raub — "theft".
Among the types of robbery are armed robbery involving use of a weapon and aggravated robbery involving use of a deadly weapon or something that appears to be a deadly weapon. Highway robbery or "mugging" takes place outside and in a public place such as a sidewalk, street, or parking lot. Carjacking is the act of stealing a car from a victim by force. Extortion is the threat to do something illegal, or the offer to not do something illegal, in the event that goods are not given, primarily using words instead of actions.
Criminal slang for robbery includes "blagging" (armed robbery, usually of a bank) or "stick-up" (derived from the verbal command to robbery targets to raise their hands in the air), and "steaming" (organized robbery on underground train systems).
