What is the term for taking someone's property by threat or force?

The term for taking someone's property by threat or force is robbery. Robbery involves not only the act of taking property but doing so in a manner that places the victim in fear or involves the use of force. This distinguishes it from simple theft, which does not require the use of intimidation or violence.

In contrast, burglary typically refers to illegally entering a building with the intent to commit a crime inside, often theft, but does not necessarily involve confrontation with a person. Theft, on the other hand, is the unlawful taking of someone else's property without force or threat, and fraud involves deception to obtain property or services, rather than outright taking it by force or threat. Thus, the definition of robbery specifically aligns with the use of force or intimidation in the act of stealing property, making it the correct answer.
