viileää

Viileä is a Finnish adjective that primarily means cool in temperature, describing air, weather, or objects that are pleasantly or briskly cold without being icy. It can also be used metaphorically to describe a calm, composed, or unflustered demeanor, or a restrained, stylish aesthetic in design and fashion.

In everyday usage, viileä can refer to the physical sensation of chill, as in ilmaa on viileä or yö on viileä. Metaphorically, it can describe a person who remains calm under pressure or acts with controlled confidence, for example, "hän on viileä asiantuntija" or "viileä asenne." In cultural and design contexts, the word contributes a sense of minimalist, modern elegance, as in phrase like "viileä ilme" or "viileä tyyli."

Grammar and inflection: the positive form is viileä. The comparative form is viileämpi, and the superlative is viilein. The adverbial form is viileästi. Like other Finnish adjectives, viileä inflects to agree with the noun it modifies in number and case (for example, viileä when modifying a singular noun, viileät when modifying a plural noun). Its usage is common in weather reports, everyday speech, and descriptive writing.
