nivellä
Nivellä is a Finnish verb derived from the noun nivel, meaning joint. The verb denotes the act of joining two parts by a joint or establishing a joint-like connection, and in anatomical contexts it can describe articulation or movement at a joint. Because of its technical meaning, nivellä is primarily found in medical, anatomical, or mechanical texts rather than in everyday speech.
In practice, nivellä appears in specialized descriptions of how components are joined or how joints function.
Etymologically, nivellä shares its root with nivel (joint) and related terms like nivelside (ligament) and nivelrikko
