A more thorough explanation:

Sub Potestate Parentis

Sub potestate parentis is a Latin term that means "under the protection of a parent." It refers to the legal responsibility and authority that parents have over their children.

For example, a child who is under the age of 18 is considered to be sub potestate parentis, meaning that their parents are responsible for their well-being and decision-making until they reach adulthood.

Another example is when a child is traveling with their parents. The child is considered to be under the protection of their parents, or sub potestate parentis, during the trip.

The examples illustrate how sub potestate parentis refers to the legal responsibility and authority that parents have over their children. It is a term that is often used in legal and historical contexts to describe the relationship between parents and their children.
