karkeissa

Karkeissa is a Finnish word that appears as the inessive plural form of the adjective karkea, meaning rough or coarse. In practical use, it signals that something exists “in rough conditions” or “in coarse materials” and is typically found in descriptive or technical language.

In ordinary and technical Finnish, karkeissa is used with plural nouns to describe states or environments characterized by roughness or coarseness. Because Finnish adjectives agree with the nouns they modify, karkeissa functions as a modifier for plural subjects and places, rather than as a standalone noun.

Common contexts for the term include descriptions of texture, surfaces, or environmental conditions. It can appear in fields such as geology, material science, or literature when contrasting smooth versus rough qualities, or when outlining the conditions under which a process occurs.

Related forms in Finnish include the base adjective karkea (rough) and the corresponding noun form karkeus (coarseness). The singular inessive form is karkeassa, while the plural inessive form is karkeissa, reflecting standard Finnish case and number agreement patterns. The term is not a proper noun and does not designate a specific place or organization; rather, it is a grammatical form used to convey state in plural contexts.
