A more thorough explanation:

Definition: Nonverbal testimony is evidence presented in a trial or hearing that does not involve spoken words. It can include photographs, drawings, maps, charts, or other depictions used to aid a witness in testifying.

Example: In a murder trial, a witness may use a map to show the location of the crime scene and where the suspect was seen. The map is a form of nonverbal testimony because it does not involve spoken words but helps the witness explain their testimony.

Nonverbal testimony is important because it can help clarify a witness's testimony and make it easier for the judge or jury to understand the evidence presented in a trial or hearing.
