virheellistä

Virheellistä is the partitive singular form of the Finnish adjective virheellinen, meaning faulty or erroneous. The term is used to describe information, data, statements, calculations, or objects that contain mistakes or are not accurate. In Finnish, adjectives agree with the noun they modify in number and case; virheellinen has the forms virheellinen (nominative singular), virheellistä (partitive singular), virheellisiä (partitive plural), and virheelliset (nominative plural).

Etymology and morphology: Virheellinen is formed from the noun virhe, meaning error or fault, plus the suffix -ellinen, which signals characteristic or possessing the property of. The word thus literally means “containing errors.” The related forms reflect Finnish inflection: virheellinen (nominal singular), virheellistä (partitive singular), virheellisiä (partitive plural), virheelliset (nominal plural).

Virheelliset laskelmät describe faulty calculations, and virheellinen väite denotes an erroneous claim. The term is common in technical, academic, and journalistic contexts where accuracy is important. The opposite is virheetön or virheettömä, meaning without errors or flawless.
