Pilferage

In the criminal law, theft (also known as stealing) is the illegal taking of another person's property without that person's freely-given consent. As a term, it is used as shorthand for all major crimes against property, encompassing offences such as burglary, embezzlement, larceny, looting, robbery, mugging, trespassing, shoplifting, intrusion, fraud (theft by deception) and sometimes criminal conversion. In some jurisdictions, theft is considered to be synonymous with larceny; in others, theft has replaced larceny.

Someone who carries out an act of or makes a career of theft is known as a thief.
