kylläste

Kylläste is a Finnish noun that denotes the state of being saturated or fully filled. It derives from the verb kyllästää, meaning to saturate or fill to capacity. In technical and scientific writing, kylläste is used to describe a condition in which no more of a substance can be added under given conditions, or where a property has reached its maximum value.

In chemistry, a saturated solution contains the maximum amount of dissolved solute at a given temperature, and adding more solute will not dissolve. The term is used to indicate that the system has reached equilibrium with respect to dissolution.

In color theory and imaging, kylläste refers to color saturation—the intensity or purity of a color. A color with high saturation appears vivid, while a desaturated color looks muted or washed out.

In physics and engineering, saturation describes a state where a system’s response no longer increases proportionally with input. For example, magnetic materials reach magnetic saturation, where further increases in the external magnetic field do not yield proportional increases in magnetization.

In biology or nutrition, the concept relates to fullness or satiety, though everyday language uses different terms. The notion of saturation also appears in discussions of processes that have reached their limit or capacity.

Usage notes: Kylläste is mainly found in formal or technical texts. In everyday Finnish, speakers more commonly use verb-based forms such as kyllästää or related nouns like kyllästyminen. See also: kyllästyminen, kyllästynyt, kyllästys.
