A more thorough explanation:

Definition: Nulla persona is a Latin term that means "no person." It refers to someone who has no legal rights, usually because of their actions or status.

For example, a person who has committed a crime and is in prison may be considered a nulla persona because they have lost their rights as a citizen. Similarly, a minor who has not yet reached the age of majority may be considered a nulla persona because they do not have all the legal rights of an adult.

These examples illustrate how the term nulla persona is used to describe someone who is not recognized as a legal person with full rights and privileges. It is important to note that this term is not used to dehumanize or diminish the value of individuals, but rather to describe their legal status.
