elastisessa

Elastisessa is the inessive singular form of the Finnish adjective elastinen. It is used to describe something that is in an elastic state or that possesses elasticity. Examples include elastisessa tilassa (in the elastic state) and elastisessa materiaalissa (in an elastic material). In Finnish grammar, adjectives agree with the noun they modify in case, number, and definiteness, so elastinen becomes elastisessa when describing a noun in the inessive case.

Etymology: The adjective elastinen derives from the concept of elasticity, with cognates in other European languages such as German elastisch and English elastic. The Finnish form reflects the same root, traced to Latin elasticus and Greek elastikos in the history of scientific vocabulary.

Usage: Elastinen is common in physics, engineering, materials science, and everyday language to describe reversibly deformable properties. The inessive form elastisessa appears in phrases like elastisessa tilassa meaning in the elastic state and elastisessa materiaalissa meaning in an elastic material. It can also describe biological tissues or textiles that exhibit elasticity.
