Sään is a Finnish term that most commonly functions as the genitive form of sää, meaning weather. In Finnish grammar, the genitive case marks a relationship or possession, and sään appears in a range of weather-related expressions. For example, sään mukaan means according to the weather, and sääolosuhteet refers to weather conditions; in these phrases the word helps describe the state of the weather rather than naming a thing.

Etymology and linguistic background: The form derives from the Proto-Finnic root *sää, a common source for weather-related vocabulary in Finnic languages. The word has cognates in related languages, such as Estonian sää, reflecting shared historical development of weather terminology across the Finnic language family.

Onomastic and toponymic usage: In addition to its grammatical role, Sään can occur as a proper noun in Nordic contexts, including as a surname or place name. Such usage is uncommon and not widely documented in standard reference works, and it is typically encountered only in specific local or historical contexts when capitalized.

Notes and distinctions: The everyday meaning of Sään aligns with weather, while capitalized forms may indicate a personal or geographical name. It should not be confused with sää, the more common word for weather, which appears more frequently in everyday Finnish.
