The word 'unworthiness' is a layered construction built upon the ancient Germanic concept of value. Its core, 'worth,' originates from the Proto-Germanic werþaz, meaning "toward" or "equivalent in value," which itself derives from the Proto-Indo-European root wert- meaning "to turn." This evolved into the Old English weorþ, signifying value, price, or honor. The prefix 'un-,' a common Germanic negation, was added to invert this core meaning, creating 'unworth' to describe a lack of value. Finally, the productive noun-forming suffix '-ness,' from Old English -nes(s), was appended to crystallize the abstract state or condition of being without worth. Thus, the term's logic moves from the foundational idea of turning toward an equivalent (value), through its negation, to the final abstraction of the resulting condition.
