aurinkoisena

Aurinkoisena is a Finnish word that functions as the essive form of the adjective aurinkoinen, meaning "sunny." It is used to describe the state of weather or atmosphere and is commonly translated as “on a sunny [day]” or simply “sunny” in descriptive text.

Grammatically, aurinkoisena is formed by adding the essive suffix -na/-nä to the adjective aurinkoinen. It is typically used with time- and weather-related nouns, for example aurinkoisena päivänä (on a sunny day) or aurinkoisena kesänä (in a sunny summer).

Usage and nuance: The form is common in written Finnish, including weather descriptions, travel writing, and poetry, where it helps create a concrete image or mood. In everyday speech, speakers may simply use aurinkoinen päivä or similar phrases, but aurinkoisena remains correct and usable when describing a temporary state of weather or atmosphere.

Etymology and related forms: The word derives from aurinko (sun) and the suffix -nen, with the essive suffix -na/-nä producing a temporary-state meaning (as sunny). Related terms include aurinko, aurinkoinen, and phrases such as aurinkoisessa säässä.
