boreaalisilla

Boreaalisilla is a Finnish grammatical form used to denote location in the boreal zone. It is the adessive plural form of the adjective boreaalinen, meaning “boreal” or “relating to the boreal region.” In Finnish, adjectives agree with the nouns they modify in number and case; boreaalisilla appears before a plural noun in the adessive case to express “in boreal …”

Example: Boreaalisilla alueilla talvet ovat pitkiä ja kylmiä.

Morphology and usage: The form derives from boreaalinen, with the adjective suffix -inen and the adessive ending -illa for plural nouns. The construction requires a following plural noun such as alueet, metsät or ympäristöt, as in boreaalisilla alueilla or boreaalisilla metsillä. The phrase communicates situational context rather than naming a standalone category.

Context and notes: The term is common in ecological, geographical, and climate literature written in Finnish. It is not a lexical noun by itself; rather, it is a grammatical inflection that enables description of phenomena occurring in boreal regions. It can be combined with various plural nouns to discuss flora, fauna, climate effects, or human activities within boreal environments. Related concepts include the boreal zone, taiga, and boreal ecology.
