äärettöminä
Äärettöminä is a Finnish grammatical form that functions as the essive plural of the adjective äärettömä/äärettöinen, meaning endless or boundless. In usage, äärettöminä describes multiple subjects as being in a state of endlessness or infinite nature, and it is most often found in literary or rhetorical contexts rather than in everyday speech. The form is derived from the stem äärettö- (endless) with the standard Finnish essive plural ending, which appears in predicative constructions with plural subjects. Because essive plurals are relatively uncommon in ordinary modern Finnish, äärettöminä is most typical in poetry, epic prose, and elevated narration, where it can convey vastness, infinity, or unboundedness.
In relation to other words, its close kin include äärettömyys, the noun meaning infinity or immeasurability,
