ZKR NQBH – ‘active, outward and receptive, inward polarity’

The root of the first of these words is כר, which expresses that which is apparent, eminent; that which serves as monument or as character, to preserve the memory of things. It is the elementary root אר united to the assimilative sign כ, and ruled by the demonstrative sign ז.

The second of these words has for root קב, whose meaning, entirely opposed to that of כר, is applied to that which is hidden and not apparent; to that which is graven, hollowed out, enveloped. The sign נ which rules it is the image of passive [receptive] action. (The Hebraic Tongue Restored, Fabré d’Olivet, p. 59)
