Tiukennus

Tiukennus is a Finnish noun meaning the act or result of making something tighter or more constricted. The word stems from the adjective tiukka (tight) plus the nominalizing suffix -nnus. In Finnish, it can describe the tightening of clothing, belts, or cords, as well as the tightening of screws, bolts, or clamps.

In engineering and manufacturing contexts, tiukennus denotes the process of applying a specified torque or tension to fasteners to achieve a desired preload. It may also refer to adjusting belts, chains, or hoses to the required tension to ensure proper function and safety.

In physiology, tiukennus can refer to constriction or stiffening of tissues or vessels. For example, vasoconstriction or muscular tiukennus can be described as a tightening of an area or structure. The term is polysemous, with usage depending on context.

Translations into English typically render tiukennus as tightening, tightness, constriction, or constrictive force. Related Finnish terms include tiukkuus (firmness) and kiristys (tightening or adjustment), though nuance differs by domain.

In sum, tiukennus covers a range of tightening-related notions from everyday wear and mechanical work to physiological constriction, making it a context-dependent term in Finnish-language texts.
