A more thorough explanation:

Term: Detentio
Definition: Detentio is a Latin term that has two meanings. In Roman law, it refers to the natural possession of property. In history, it means being held or detained, but not necessarily captured.
Examples: If someone is held in a prison cell, that is captio. But if someone is held in a room and not allowed to leave, that is detentio. Another example is when a person is stopped by the police for questioning, but not arrested. That is also detentio.
Explanation: The examples illustrate that detentio is a form of detention or holding, but it is not always the same as being captured or arrested. It can be used to describe situations where someone is being held against their will, but not necessarily in a criminal context.
