A more thorough explanation:

Definition: Delatio (di-lay-shee-oh), n. [from Latin deferre "to denounce"] is a term used in Roman and civil law to refer to an accusation or information.

Examples:

• He made a delatio to the authorities about his neighbor's illegal activities.
• The delatio of the crime was made by a witness who saw the suspect leaving the scene.

These examples illustrate how delatio is used to describe the act of accusing or informing someone about a wrongdoing. In the first example, someone reports their neighbor's illegal activities to the authorities. In the second example, a witness reports what they saw to the authorities. In both cases, delatio is used to describe the act of reporting or accusing someone of a crime.
