primær

Primär is a German adjective meaning primary, principal, or original. It derives from Latin primarius and is used to distinguish concepts from their secondary counterparts (sekundär). In German, primär is commonly found in compound terms across various fields, such as Primärquelle, Primärliteratur, Primärforschung, and Primärdaten, where it signals origin, importance, or foundational status.

In linguistic and scholarly contexts, Primärquellen or Primärquellen refer to original materials used as the basis for analysis, such as historical documents, original datasets, or firsthand field notes. Primärforschung denotes original research conducted to generate new data, as opposed to Sekundärforschung, which analyzes existing sources and data. In information technology, Primärschlüssel or primary key is a database concept that uniquely identifies records, while Primärspeicher (main memory) refers to the primary storage used by a computer.

In the natural sciences, Primärstruktur describes the linear sequence of units in a macromolecule, for example the amino acid sequence in a protein. In energy studies, Primärenergie denotes energy found in nature before transformation, including fossil fuels and natural resources, contrasting with Sekundärenergie such as electricity or refined energy forms. In color theory, Primärfarben describes base colors, with definitions varying by model: additive systems (red, green, blue) differ from subtractive systems (cyan, magenta, yellow) in what is considered primary.

The term Primär is versatile in German and appears in academic, technical, and everyday language to indicate priority, originality, or a foundational level. It is commonly paired with words for which a clear contrast to secondary or derived concepts is intended. See also Sekundär, Primärdaten, Primärquelle.
