definitsiooniliselt

definitsiooniliselt is an Estonian adverb that translates to "definitionally" or "by definition" in English. It is used to indicate that something is true or understood based on its inherent meaning or the established definition of a term. The word is formed from the Estonian noun "definitsioon" (definition) and the adverbial suffix "-liselt". It implies that a characteristic or state is not a matter of opinion or empirical observation, but rather a necessary consequence of what something is.

For example, if one states that "a triangle is definitionally a three-sided polygon," they are asserting that the property of having three sides is intrinsic to the definition of a triangle. The word "definitsiooniliselt" emphasizes that this truth is derived solely from the concept itself. It is often employed in logical arguments, philosophical discussions, or when clarifying the precise meaning of a word or concept. Its usage ensures that the point being made is understood as an essential attribute, not an accidental one.
