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. In medicine, the term may be used to discuss how bones or implants connect at a joint, or how a joint operates within a range of motion. In engineering or carpentry, nivellä can describe the creation or maintenance of hinged or articulated connections between parts. Due to its technical character, alternative Finnish verbs such as liittää or artikuloida may be used depending on the context and audience.

Etymologically, nivellä shares its root with nivel (joint) and related terms like nivelside (ligament) and nivelrikko (osteoarthritis). The word is part of the broader medical and technical vocabulary built around the concept of joints and articulation in the body and in engineered assemblies.
