Which term describes entering a property to commit a crime without permission?

The term that specifically refers to entering a property to commit a crime without the owner's permission is burglary. Burglary involves unlawful entry with the intent to commit a crime once inside, which may include theft, vandalism, or other illegal activities.

Robbery, on the other hand, involves taking property from a person with the use of force or intimidation, which is a different scenario that does not focus solely on the unauthorized entry aspect. Trespassing does involve entering someone else's property without permission, but it does not necessarily imply the intent to commit an additional crime beyond the act of intrusion itself.

Assault refers to an act that causes another person to fear imminent physical harm and is unrelated to property crimes or unauthorized entry. Thus, the correct choice in the context of this question is burglary, as it encapsulates both the unlawful entry and the intent to commit a crime inside.
