A more thorough explanation:

Definition: Personal exception; an exception based on personal reasons.

Example: A student may request a personali exceptione to a school policy if they have a medical condition that prevents them from following the policy.

This means that the student is asking for an exception to be made for them based on their personal situation. The term personali exceptione is often used in legal or historical contexts to describe situations where an individual is granted an exception based on their personal circumstances.
