A more thorough explanation:

PRIVATUM

Privatum means "private" in Latin. It was often used in phrases like jus privatum, which means "private law".

• A person's diary is their privatum property.
• Companies have privatum information that they don't share with the public.
• In ancient Rome, jus privatum referred to the laws that governed private citizens and their property.

The examples illustrate that privatum refers to something that is not public or shared with others. It can refer to personal property, confidential information, or laws that apply to individuals rather than the government or society as a whole.
