Sumuinen

Sumuinen is a Finnish adjective meaning foggy or misty. It describes weather, light, or landscapes where fog or haze reduces visibility and creates a soft, blurred appearance. The word conveys mood as well as physical conditions, often signaling still air and quiet surroundings.

Etymology and formation: sumuinen is derived from the noun sumu, fog or haze, combined with the adjectival suffix -inen to form an attribute. In Finnish, adjectives agree with the noun in number and case; the base form is sumuinen, the plural nominative is sumuiset, and phrases such as sumuinen aamu or sumuinen järvi are common.

Usage and nuance: sumuinen is typically used for natural scenes and weather reports, but it also appears in poetry and prose to evoke atmosphere. It is closely related to words like hämärä (dim, dusk) and sumu (fog); however, sumuinen emphasizes the hazy, cloudy quality rather than the light level alone. The term is widely understood across Finnish-speaking regions and is common in autumn and spring when fog is frequent.
