vuoriston

Vuoriston is the genitive singular form of the Finnish noun vuoristo, meaning “mountain range.” It is used to denote possession or association with a mountain range in Finnish phrases. Examples include vuoriston rinteet (the slopes of the mountain range), vuoriston yli (over the mountain range), and vuoriston ekosysteemi (the ecosystem of the mountain range). The form is also common in geographic names to indicate features belonging to or located within a particular range.

Etymology and form: Vuoristo, derived from vuori meaning “mountain,” combines with the suffix -sto to form a collective noun for a range of mountains. The genitive singular ending -n yields vuoriston, which marks “of the mountain range.” The word follows regular Finnish declension patterns for genitive usage and does not require an article.

Grammar and usage: In Finnish, the genitive case is used to express possession, association, or attribution. Vuoriston functions similarly within a noun phrase, modifying another noun or standing in constructions that indicate location or characteristic related to the mountain range. Because Finnish lacks articles, vuoriston conveys its sense through case and context rather than a definite or indefinite article.
