Korrektur

Korrektur is a German noun meaning correction, adjustment, or rectification. The word derives from Latin correctio, with related forms in many European languages. In everyday German, it is used for changes that make something accurate or proper and for formal processes of correcting texts or data.

In publishing and editing, Korrektur refers to proofreading and the subsequent corrections made to a text before final printing. The person performing this work is a Korrektor or Korrekturleser; corrections—spelling, punctuation, factual errors, or layout issues—are often indicated with Korrekturzeichen (proofreading marks). The stage is part of a typical editorial workflow alongside Lektorat (content editing) and Drucklegung (printing).

In science and engineering, Korrektur describes adjustments that compensate for known biases or errors. Common instances are calibration of instruments and the application of correction factors (Korrekturfaktoren) to data or models, so measurements reflect true values as closely as possible.

In finance and economics, a Korrektur can denote a market correction, a decline from recent highs of a significant magnitude, typically around 10% or more, before a new trend emerges.

Other uses include medicine, where Korrektur can denote the surgical or therapeutic correction of deformities, and in education where corrections are made to errors in assignments or examinations.

Overall, Korrektur captures the broad idea of making something right by removing error or bias, whether in language, measurement, finance, or medicine.
