The term "de facto" is Latin for "in fact" or "in reality." It describes a situation, practice, or condition that exists in reality, regardless of whether it is officially recognized by laws or formal rules. It is often used to contrast with "de jure," which means "by law" or "officially." For example, a "de facto government" is one that holds power and functions in reality, even if it lacks legal recognition. Similarly, a "de facto parent" is someone who acts as a parent in practice, even if not legally recognized as such.
