Jednostronny

Jednostronny is a Polish adjective meaning one-sided or unilateral. It describes something that pertains to, or affects, only one side or party. The term can be used across domains, including law, politics, medicine, and everyday language.

In law and politics, phrases such as a unilateral decision (decyzja jednostronna) or a unilateral contract (umowa jednostronna) denote actions taken by a single party without the consent of others. In media or discourse, a unilateral perspective (jednostronna perspektywa) or portrayal (przedstawienie jednostronne) denotes a view that presents only one side of an issue. In medicine, it is used to describe conditions affecting one side, for example unilateral pain (ból jednostronny) or unilateral paralysis (porażenie jednostronne).

The word is often contrasted with dwustronny, meaning bilateral or two-sided. Etymologically, jednostronny is formed from the root strona (side) with a prefix that signals a single side, yielding the sense of “pertaining to one side.” The noun form, jednostronność, expresses the quality or state of being unilateral.
