pysyneistä

Pysyneistä refers to a Finnish colloquial term, essentially meaning "everlasting" or "permanent," often used humorously or to describe something that is unexpectedly or annoyingly persistent. It is not a formal scientific or technical term but rather a part of everyday Finnish language.

The word derives from "pysyä," which means "to stay" or "to remain." When combined with the plural genitive suffix "-istä," it creates a sense of enduring permanence. For example, one might jokingly refer to a stubborn stain as a "pysyneistä" if it refuses to be removed. Similarly, a long and drawn-out event, or a person who overstays their welcome, could be described as "pysyneistä."

The usage of pysyneistä is context-dependent and carries a lighthearted, sometimes exasperated, tone. It highlights a situation or object that has outstayed its welcome or proven to be more tenacious than anticipated. It is a versatile expression used in informal conversations among Finnish speakers to add a touch of humor to everyday observations about things that just don't seem to go away.
