virheellä

Virheellä is the adessive singular form of the Finnish noun virhe, meaning a mistake or error. In Finnish grammar, the adessive (-llä) marks instrumental means or the manner in which something is done, and it can also be used in formal language to indicate the cause of an event. Therefore virheellä can convey readings such as “with a mistake,” “by means of an error,” or “due to a fault,” depending on the context.

The term is most common in formal, administrative, or technical writing where a result is attributed to an error in data, procedure, or calculation, or where the manner of performing an action involves a fault. In everyday speech, this exact form is less frequent, and speakers typically prefer expressions like virheen vuoksi (because of the error), virheestä johtuen (due to the error), or virheellisesti (incorrectly) to describe cause or manner.

Morphology and usage notes: virheellä is the singular adessive form; the plural form is virheillä. The adessive usage is mainly reserved for contexts that require a precise description of when, how, or why something occurred due to an error. In common language, even when referring to errors, more natural phrasing often exists, such as statements using virheen vuoksi or virheestä johtuen.

Overall, virheellä functions as a specialized grammatical tool for attributing actions or outcomes to an error in formal Finnish, while everyday expression tends toward other constructions that convey the same idea more idiomatically.
