singulært

Singulært is a Norwegian adjective meaning “singular” or “unique” and is used to describe things that stand apart from the ordinary or occur as a single item. The term appears in several domains with related but distinct meanings, including language, mathematics, and science, as well as in everyday discourse.

In linguistics and grammar, singulært denotes the singular form of a noun, pronoun, or verb, referring to one entity as opposed to a plural reference. It is used in descriptions of grammatical number and agreement, particularly in language teaching and reference grammars.

In mathematics and geometry, a singular point is a location where a geometric object fails to be smooth or well-behaved. For a curve defined by a polynomial, a point is singular if the function and its partial derivatives satisfy specific vanishing conditions, leading to a non-smooth or non-regular structure. More broadly, singularity can refer to points or configurations where standard tools (like tangent planes or invertible mappings) cease to apply.

In physics and cosmology, singularities describe points where physical quantities become infinite or theories lose predictive power, such as in black holes or the Big Bang. They signal limits of current models and motivate the search for more comprehensive theories.

Etymologically, singulært derives from the Latin singulus, meaning “one” or “single.” In common usage, it retains the sense of something exceptional or not part of the ordinary.
