Trägers

Trägers is the genitive singular form of the German noun Träger, which means carrier, bearer, or support. In everyday German, Trägers itself is rarely used as a stand-alone term; it typically appears as des Trägers or in compound words.

In construction, a Träger is a beam or girder that carries loads, for example Dachträger (roof beam) or Stahlträger (steel beam).

In biology and medicine, a Träger refers to an organism or person that carries a pathogen or genetic trait, especially when symptoms are not present; these carriers can transmit disease or carry alleles without expression.

In electronics and communications, the term Träger denotes a carrier signal used to convey information, as in Trägersignal or Trägerfrequenz in modulation.

In pharmaceuticals and materials science, Träger systems or carriers are substances that deliver drugs, catalysts, or imaging agents to a target site, often through encapsulation or adsorption.

Etymology: Träger derives from tragen, "to carry"; the possessive/genitive form is des Trägers; in compounds the form Träger is common, and the inflected form Trägers appears mainly in grammar rather than as a standalone concept.
