kõverjoonelisel

Kõverjooneline is an Estonian adjective meaning curvilinear or curved, used to describe lines, paths, or shapes that deviate from a straight form. It indicates that an object follows a smooth bend rather than a straight segment. The form kõverjoonelisel is a inflected variant typically used with nouns in cases such as inessive or adessive, for example kõverjoonelisel teel (on a curvilinear road) or kõverjoonelisel kujul (in a curvilinear form).

The term is common in several fields. In mathematics and geometry, kõverjooneline describes curves as opposed to straight lines, and appears in discussions of curvature, parametric representations, or curve fitting. In cartography and geospatial contexts, kõverjooneline coordinates or trajectories are used to model routes and shapes that are not linear. In design, architecture, and computer graphics, kõverjooneline forms are contrasted with linear or angular designs to convey fluidity or organic movement.

Etymology reflects its meaning: the compound combines kõver (curved) with jooneline (line-like), underscoring a departure from straightness. As a result, kõverjooneline is widely understood by Estonian speakers to denote anything that follows a curved, bending path, whether in natural forms, technical diagrams, or visual representations.
