n. the crime of breaking and entering into a structure for the purpose of committing a crime. No great force is needed (pushing open a door or slipping through an open window is sufficient) if the entry is unauthorized. Contrary to common belief, a burglary is not necessarily for theft. It can apply to any crime, such as assault or sexual harassment, whether the intended criminal act is committed or not. Originally under English common law burglary was limited to entry in residences at night, but it has been expanded to all criminal entries into any building, or even into a vehicle.
