Kupariset

Kupariset is the Finnish plural form of the adjective kuparinen, meaning coppery or made of copper. The term is used to describe objects, materials, or colors that have the appearance or composition of copper. In everyday Finnish, kupariset can modify plural nouns such as korut (jewelry), levyt (plates or sheets), or esineet (items).

Etymology and grammar: The base word kupari means copper. The adjective is formed with the suffix -inen, and when referring to plural nouns it inflects to kupariset in the nominative. The form agrees with the noun it describes in number and case, as is standard in Finnish grammar.

Usage and contexts: Kupariset is common in catalogues, descriptions, and discussions of objects with copper surfaces or finishes, for example kupariset korut (copper jewelry), kupariset levyt (copper sheets), or kuparisen pinnan tapauksessa referring to a copper-colored coating. The term can also describe a copper-toned appearance in art and design, such as a kuparisen sävy (coppery shade). It is not a proper noun and does not designate a specific group or organization.

Related forms: The singular form is kuparinen, used for singular nouns like kuparinen koru (a copper jewelry piece). The concept is part of standard Finnish color/material vocabulary, alongside other material adjectives such as hopeanen (silver) and rautainen (iron or iron-like).
