burgle

To burgle is to break into a building in order to steal. The entering is what makes it burglary rather than theft.

British English says burgle and American English says burglarize, which is one of the more noticeable differences between them, and both were formed backwards from the noun burglar. The passive is the common form, since people say they have been burgled rather than that somebody burgled them. Break in is the plainer phrase and does not require the intent to steal.
