Graderna

Graderna is the definite plural form of the Swedish noun grad, and it is used for several related concepts centered on the idea of a degree or a step. In everyday Swedish, graderna denotes a set of degrees or levels on a scale, and its exact meaning depends on context.

The most common senses are:

- Temperature: when Celsius or another scale is implied, as in “20 grader,” meaning 20 degrees.

- Angles and circular measures: a degree is one three-hundred-sixtyth of a circle, so phrases like “90 grader” refer to right angles.

- Levels on a scale or rubric: grader can denote steps or categories within a ranking or assessment system, such as quality or intensity levels.

In mathematics and related disciplines, grad is also used to denote the degree of a polynomial (for example, a polynomial of degree n). When discussing several polynomials, one could refer to their degrees in the plural, though wording is often more specific in such cases.

Graderna may also appear as a proper noun in some contexts, such as place names or organizational titles, in which case it is capitalized. As a common noun, its meaning is determined by the surrounding words and the field of discourse, making it a term with multiple closely related uses rather than a single fixed topic.
