If you're charged with Breaking and Entering, the prosecution must prove that you broke into and entered a structure with the intent to commit a crime while in the building. Most often the crime that the prosecutor will use to prove breaking and entering is larceny, but they can also prove that you broke into the house with the intent to commit a more or less serious crime.
The breaking part of Breaking and Entering means that you applied some amount of force to enter a structure. It can be simply pushing open an already slightly open door. You do not have to actually break something. For example, if you open an unlocked window, that would be breaking.
Entering can be any intrusion into a building. If you walk into the building, that's entering. But it's also entering if you stick your finger or a tool into a building.
There are several different kinds of breaking and entering. For example, if you breaking into a home at night using a deadly weapon, it's a Class 2 felony. A Class 2 felony is punishable by up to life in prison. But if you are convicted of breaking into a building with the intent to commit a misdemeanor, it could be a Class 6 felony. A Class 6 felony only carries up to 5 years in prison. Your actual punishment in each case will depend on many different factors, including your criminal record.
