What is defined as entering a commercial establishment with the intent to commit larceny?

The correct answer is that entering a commercial establishment with the intent to commit larceny is defined as burglary. This term specifically refers to the unlawful entry into a building or property with the intention of committing a crime inside, which often involves theft or larceny.

When it comes to the other terms, robbery involves taking property from a person using force or intimidation, which differs fundamentally from simply entering a structure with intent to steal. Shoplifting refers specifically to the act of stealing goods from a retail establishment without necessarily entering with criminal intent, as someone could steal items surreptitiously while shopping. Trespass is the act of entering someone's property without permission, which does not inherently include the intent to commit larceny.

Thus, the definition provided in the question aligns specifically with burglary, underscoring how legal terminology addresses the nuances of unlawful entry and intent to commit theft.
