Markör

Markör is a noun used in Nordic languages (Swedish markör, Norwegian Bokmål markør, Danish markør) to denote something that marks, identifies, or indicates. The term is versatile and appears across daily language and specialized fields, often describing an indicator, pointer, or label.

In everyday and technological contexts, markör can refer to a marker or highlighter used to mark text or objects, or to the cursor/pointer on a computer screen. The sense of marking or signaling is central: a markör is something that designates a position, state, or feature.

In science and medicine, markör has a broader, more technical meaning. It denotes an indicator used to identify, classify, or measure a biological or clinical property. Common examples include genetic markör, a DNA sequence with a known location used in linkage analysis and population studies, and biomarkør, a molecule or characteristic that signals a physiological or pathological state. In immunology and cell biology, cell-surface markörer refer to proteins used to identify and distinguish cell types, such as the CD markers in immunophenotyping.

The term emphasizes marking or signaling rather than constituting the thing itself, and is often paired with a modifier to specify the domain (genetisk markör, immunologisk markör, etc.). English speakers generally use the term marker, while the Nordic forms retain the explicit reference to marking. The usage reflects the common idea of a detectable feature that helps identify, characterize, or track a property or object.
