Break and enter

Burglary (also called breaking and entering and sometimes housebreaking) is an unlawful entry into a building or other location for the purposes of committing an offence. Usually that offence is theft, but most jurisdictions include others within the ambit of burglary. To engage in the act of burglary is to burgle (in British English) or to burglarize (in American English).

At common law, burglary was defined by Sir Matthew Hale as:

The breaking and entering the house of another in the night time, with intent to commit a felony therein, whether the felony be actually committed or not.

The common law elements of burglary often vary between jurisdictions. The common law definition has been expanded in most jurisdictions, such that the building need not be a dwelling or even a building in the conventional sense, physical breaking is not necessary, the entry does not need to occur at night, and the intent may be to commit any felony or theft.

The etymology originates from Anglo-Saxon or Old English, one of the Germanic languages. According to one textbook, "The word burglar comes from the two German words burg, meaning "house", and laron, meaning "thief" (literally "house thief"). Another suggested etymology is from the later Latin word burgare, "to break open" or "to commit burglary", from burgus, meaning "fortress" or "castle", with the word then passing through French and Middle English, with influence from the Latin latro, "thief". The British verb "burgle" is a late back-formation.

In Canada, breaking and entering is prohibited by section 348 of the Criminal Code and is a hybrid offence. Breaking and entering is defined as trespassing with intent to commit an indictable offence. The crime is commonly referred to in Canada as break and enter, which in turn is often shortened to B and E.
