virheisistä

Virheisistä is a Finnish term used primarily in technical and scholarly Finnish to denote multiple errors or faulty items. It is formed from the root virhe- meaning "error" or "fault," together with the adjectival suffix -inen, giving virheinen meaning "faulty" or "error-prone." The ending -istä marks the genitive plural, so virheisistä translates roughly to "of the erroneous ones" or "from the erroneous ones." In practice, virheisistä is used in phrases where the noun that would govern the phrase is in the genitive case, for example: virheisistä laskuista johtuvat poikkeamat (deviations arising from erroneous calculations) or virheisistä havainnoista peräisin olevat johtopäätökset (conclusions derived from faulty observations).

This form is seen in scientific writing, auditing, quality control, and linguistic analyses where error sources are discussed collectively. It is less common in everyday Finnish, where simpler virheistä (from errors) or virheelliset (the faulty ones) might be used. The term illustrates how Finnish can express attributive fault with adjectival forms aligned to a noun in a genitive construction, providing a compact way to refer to a set of items considered faulty.
