vilpillisesti

Vilpillisesti is a Finnish adverb meaning "dishonestly" or "fraudulently." It describes actions performed with deceit, trickery, or an intent to mislead, typically to gain an unfair advantage or to conceal the truth. The word conveys a strong negative judgment about the conduct described.

Etymology and form: Vilpillisesti is derived from the adjective vilpillinen (deceitful). The root vilppi means deception or trickery. The -llinen suffix forms the adjective, and the -isesti suffix yields the corresponding adverb, yielding the sense "in a deceitful manner."

Usage: The term is mainly used in formal, journalistic, or legal contexts. It emphasizes intentional wrongdoing rather than mere error and tends to carry a strong condemnation. Related terms include vilpillinen (deceitful) and vilppi (deception).

Example: Hän myi tuotteen vilpillisesti. (He sold the product deceitfully.)
