sumuisissa

Sumuisissa is a Finnish adjective form that conveys the sense of “in fog,” “foggy,” or “fog-covered.” It is the inessive plural form of the adjective sumuinen and is used to describe plural nouns in phrases that denote location, mood, or atmosphere, such as sumuisissa maisemissa (in foggy landscapes), sumuisissa öissä (in foggy nights), or sumuisissa metsissä (in foggy forests). In Finnish, such inflected forms are common for expressing where something is or what it is like under certain conditions.

Linguistic notes: The root sumu refers to fog or mist, to which the suffix -inen creates the adjective sumuinen. When describing plural nouns in the inessive you typically attach -issa/-issä, yielding sumuisissa. This usage is frequent in descriptive writing and weather reporting to evoke mood and scenery. The form is not a standalone noun but a grammatical inflection that aligns with the number and case of the noun it modifies.

Cultural usage: While sumuisissa is not a proper noun or title by itself, it appears in Finnish poetry, prose, and journalism as a vivid image of muffled air and muted light. The phrase is commonly employed to evoke atmosphere or season, particularly in contexts describing fog, mist, or damp, cool conditions that obscure visibility and soften outlines of the landscape.
