How is "de facto" defined?

The term "de facto" is best defined as "in fact." It is used to describe practices or situations that exist in reality, even if they are not officially sanctioned or legally established. While "in reality" and "in fact" are quite similar, "de facto" emphasizes the practical existence or acceptance of something as true or active, regardless of any official status.

In legal and social contexts, something that is considered de facto has reality and influence in practice, even if it lacks formal recognition. For example, a de facto leader may not hold an official title but still exerts power and influence. The importance of understanding this term lies in recognizing how practices and roles can operate outside formal structures.

Other options, while related, do not capture the complete essence of "de facto." "By law" refers specifically to something that is legally recognized, whereas "in principle" pertains more to theoretical or agreed-upon norms rather than actual practices. The nuance between "in reality" and "in fact" is subtle, but "in fact" aligns most closely with the definition of "de facto," highlighting the emphasis on the actual state of affairs.
