elastisilla

Elastisilla is a Finnish inflected form of the adjective elastinen, meaning elastic or relating to elasticity. In Finnish grammar it is the plural adessive form used with plural nouns in the adessive case, for example elastisilla materiaaleilla or elastisilla kuiduilla. In context, this form often appears in technical and descriptive writing to indicate materials or features that are elastic.

The root of the word is elast-, derived from Greek elastikos, meaning capable of being drawn or expanded, with later influence through Latin elasticus and other European languages. In Finnish, elastinen and its related forms are used to describe physical properties of matter, tissues, textiles, and other systems that return to their original shape after deformation. The noun expressing the broader concept of elasticity is elastisuus, and there is also a related biological term elastiini referring to the protein elastin that provides elasticity to connective tissues.

Common fields of usage include materials science, textile engineering, biomechanics, and physiology, where discussions about stretch, resilience, and deformability arise. In economics, elasticity is used in phrases such as kysynnän elastisuus, but elastisilla as a morphological form is typically limited to grammatical agreement with plural nouns in the adessive or related cases.

Examples of usage illustrate its function as a descriptive form rather than a separate concept: elastisilla materiaaleilla valmistetut tuotteet describe products made with elastic materials; elastisilla kuiduilla tarkoitetut kankaat refer to fabrics made from elastic fibers. Overall, elastisilla serves as a standard Finnish grammatical form to convey elasticity-related attributes in plural, context-dependent sentences.
