Linjerna

Linjerna is the definite plural form of the Swedish noun linje, meaning line. In Swedish usage, linjerna refers to lines in several domains, including mathematics, transportation, and everyday descriptions of routes or contours. As a generic term, linjerna does not designate a single entity but a range of related concepts tied to the idea of a line.

In mathematics and geometry, linjerna describe straight one‑dimensional figures that extend without end in both directions. A line is defined by a point and a direction, has no width, and is considered to continue indefinitely within a plane or space. Lines may intersect, be parallel (never meeting), or be skew (non‑coplanar).

In transportation and geography, linjerna denote routes or services, such as bus lines or railway lines. Timetables and maps use the term to point to specific services or corridors between locations.

In culture and design, lines are fundamental elements of art, graphic design, and typography. Linjerna may refer to line-based drawings, outlines, or the visual rhythm created by linear elements. In textual contexts, lines can denote lines of poetry or prose when discussing layout.

Origin and usage: The term derives from Swedish linje, with the definite plural suffix -na. Linjerna is mainly used in Swedish writing and is typically translated as "the lines" in English.
