Koristeellisissa

Koristeellisissa is the inessive plural form of the Finnish adjective koristeellinen, meaning decorative or ornamental. It is used when describing nouns in the inessive case in plural, effectively translating to “in decorative/ornamental [things]” or “decorative ones.” For example, in a phrase like koristellisuus tiloissa? The correct usage would be koristeellisissa tiloissa, meaning “in decorative spaces.” In this form, both the noun and the adjective agree in number and case.

Usage and function

Koristeellisissa appears in contexts where authors discuss design, architecture, art, or interior spaces that emphasize ornamentation. It is common in descriptive writing, critiques, and academic Finnish to convey a sense of elaborate or ornamental styling. The form helps distinguish mere decoration from a broader category of decorative features present in a setting. As with other Finnish adjectives, koristelige llisissa is declined to match the noun it accompanies; it can pair with plurals in various inessive phrases, such as koristeellisissa esineissä (in decorative objects) or koristeellisissa rakenteissa (in ornamental structures).

Etymology and related forms
