IPA: /ˈbɜːɡləri/
KK: /ˈbɜrɡləri/
The act of entering a building or property without permission, usually to steal something.
The police arrested him for burglary after they found him inside the house.
Burglary is formed from "burglar" (from Old French *burglar*, meaning a thief who breaks into a house) and "-y" (a suffix used to form nouns indicating a state or condition). The word "burglary" refers to the act or condition of breaking into a building with the intent to commit theft.
Think of a 'burglar' as someone who breaks into a place, and the '-y' indicates the act or condition of that breaking in — that's why burglary means the act of breaking in to steal.
