jäykimmät

Jäykimmät is the Finnish adjective phrase meaning “the stiffest” or “the most rigid.” It is the plural nominative superlative form of the adjective jäykkä and is used when referring to multiple items that have the highest degree of stiffness or rigidity among a group. The word can describe physical properties, such as materials, tissues, or joints, as well as figurative rigidity in behavior, rules, or attitudes.

In Finnish, jäykimmät functions as a descriptive modifier placed before or after a noun, agreeing in number with the noun it modifies. The form signals a definitive ranking within a set and is commonly found in technical, scientific, or everyday language when emphasizing extreme stiffness.

Usage examples:

- Nämä kolme materiaalia ovat jäykimmät kokeessa. (These three materials are the stiffest in the test.)

- Jäykimmät säännöt hidastavat toimintaa. (The stiffest rules slow down operation.)

Jäykimmät is closely related to jäykkä, the base meaning “stiff” or “rigid,” and to its other comparative forms, such as jäykempi (stiffer) and jäykä. The term is versatile in both physical contexts and figurative expressions of inflexibility.
