A more thorough explanation:

Definition: Conceptum (pronounced kuhn-sep-tuhm) is a term used in civil law to describe a theft in which the stolen item was found in someone's possession and witnessed by others.

Example: Furtum conceptum is a type of theft in Roman law where the thief is caught with the stolen property in their possession after a search with witnesses. The possessor of the stolen property was required to pay the owner three times the value of the stolen property and could bring an action against the thief to recover triple damages.

This example illustrates how conceptum is used in the context of theft in civil law. It shows that the term is used to describe a specific type of theft where the stolen property is found in the possession of the thief and witnessed by others.
