Wornness comes from worn (past participle of wear) + -ness, from Old English werian ('to wear, carry'). In current use it is a noun meaning "the state of being worn, frayed, or exhausted". That sense is explained by the older material without requiring a speculative semantic step: the inherited or borrowed base supplies the field of meaning, while the English formation fixes its modern role. The suffix -ness turns a quality into a noun of state, condition, or degree. The surface form is compositional: its joined elements remain visible in the modern word. The historical chain includes Old English werian and Proto-Germanic *wazjaną. Related English forms include worn, wear, and worn-out. The word's history is thus visible in its construction: the components remain interpretable even after the whole expression has settled into a conventional English meaning.
