What is a common element found in definitions of theft?

The common element found in definitions of theft is consent. Theft fundamentally involves taking someone else's property without their permission. This lack of consent is a crucial component that distinguishes theft from other actions, such as borrowing or purchasing, where permission is granted by the owner.

Other options, while they may play a role in certain contexts or specific legal definitions, do not capture the essence of theft as effectively as the absence of consent. For example, the time of day might influence the circumstances of a theft but is not a defining factor. Similarly, the value of property can impact the severity of the charge but does not fundamentally alter the definition of the act itself. Lastly, the location of the offense may be relevant to jurisdiction or law enforcement but does not relate to the core concept of taking property without consent. Thus, the presence or absence of consent is critical for identifying theft.
