Joustamattomalla

Joustamattomalla is the adessive singular form of the Finnish adjective joustamaton, meaning inflexible or not elastic. It is used to describe objects, materials, or systems that resist deformation or do not return to their original shape after being deformed. In practice, it appears in phrases such as joustamattomalla materiaalilla (on an inelastic material) or joustamattomalla tavalla (in an inflexible manner). The form can also be used figuratively to describe a person who is stubborn or unyielding.

Etymology and form: Joustamaton derives from the verb joustaa, meaning to spring or be elastic, with the negating suffix -maton, combined with the adessive -lla to indicate the context or means. The phrase joustamattomalla therefore literally conveys “on/with/in an inflexible [item].”

Usage: In science, engineering and materials science, joustamattomalla describes materials or joints that do not exhibit elastic rebound after deformation. It contrasts with joustava (elastic) and the concept of elasticity (joustavuus). The term can also appear in everyday language in a figurative sense, referring to approaches, attitudes, or behaviors perceived as rigid or uncompromising.

Related terms: joustava, joustavuus, and other descriptors of material properties and behavior under stress. While joustamattomalla is most common in technical or descriptive contexts, it may be used more broadly to convey a sense of inflexibility in both objects and people.
