A more thorough explanation:

Definition: Sub sigillo is a Latin term that means "under the seal (of confession)". It refers to information that is shared in the strictest confidence.

Example: When a person goes to confession, they are sharing their sins with a priest under sub sigillo. This means that the priest cannot share this information with anyone else, as it is considered confidential.

Explanation: The example illustrates how sub sigillo is used in the context of confession. The person confessing their sins expects that the information they share will be kept confidential by the priest, who is bound by the seal of confession. This is an example of information shared in the strictest confidence.
