Aurinkoiset

Aurinkoiset is a Finnish adjective meaning sunny, used in its plural form to describe nouns that are sunny or cheerful. It functions as a descriptive modifier and agrees with the noun in number and case, for example aurinkoiset päivät (sunny days) and aurinkoiset ihmiset (cheerful people). The word is the plural form of the base adjective aurinkoinen, which itself derives from aurinko (sun) plus the adjectival suffix -inen.

Etymology and form: aurinkoinen is formed from aurinko (sun) with the -oinen suffix, a common Finnish pattern for producing adjectives meaning -like or -bearing. In the plural nominative, the form becomes aurinkoiset, which then agrees with plural nouns. The same stem can appear in different cases, such as aurinkoisessa päivässä (in a sunny day) or aurinkoisia päiviä (sunny days, partitive plural).

Usage: Aurinkoiset is widely used in everyday language, meteorology, and travel writing to evoke brightness and optimism. It often refers to weather that is bright and free of clouds, but can also describe moods, atmospheres, or scenes characterized by light and warmth. The term can be used both descriptively and as a stylistic device in prose and poetry to convey positivity.
