Viileissä

Viileissä is the inessive plural form of the Finnish adjective viileä, meaning "cool" or "chilly." In Finnish, adjectives agree with the nouns they modify in number and case, and the inessive case marks location roughly equivalent to "in" or "inside." The singular inessive is viileässä, while the plural inessive is viileissä. This form is used when describing multiple objects or plural locations that are cool.

The form viileissä appears primarily with plural nouns or noun phrases in inessive context. It conveys temperature, atmosphere, or climate in a plural setting. For example, viileissä tiloissa means "in the cool spaces," and viileissä huoneissa means "in the cool rooms." The construction can also describe situations or conditions that are cool across multiple items or places, such as viileissä olosuhteissa, meaning "in cool conditions."

Usage notes: viileissä is a standard part of Finnish adjective declension and is most common in descriptive prose, weather-related text, or spatial descriptions. It should be paired with a plural noun in the same clause (e.g., tiloissa, huoneissa, olosuhteissa). The form is distinct from the singular viileässä (in the cool) and is not typically used on its own without a following plural noun or plural context.
