by definition

By its nature

By definition means as an inherent or essential quality—something true because of what the thing fundamentally is: A bachelor is, by definition, unmarried.

The phrase emphasizes that a characteristic follows necessarily from the very meaning of a term, not from circumstance or opinion: Dictatorships are by definition undemocratic.
