Theft/larceny is typically defined as the taking of almost anything of value without the consent of the owner, with the intent to permanently deprive him or her of the value of the property taken. Most states recognize degrees of theft, such as "grand" or "petty," which usually relate to the value of the property taken.
For example, Bob goes to Jim's music store, puts two CDs in his pocket, and walks out the door. Bob can be charged with theft/larceny. Had Bob stolen Jim's car from the parking lot, Bob would likely be charged with grand theft/larceny.
