Code words may also label the sources of various documents; for example, there are code words used to indicate that a document may break the cover of intelligence operatives if its content becomes known.

Famous quotes containing the word categories:

    All cultural change reduces itself to a difference of categories. All revolutions, whether in the sciences or world history, occur merely because spirit has changed its categories in order to understand and examine what belongs to it, in order to possess and grasp itself in a truer, deeper, more intimate and unified manner.
    Georg Wilhelm Friedrich Hegel (1770–1831)
