Whiteness comes from Old English hwītnes, from hwīt ('white') + -nes, from Proto-Germanic *hwītaz, from Proto-Indo-European *kweid- ('to shine, be bright'). In current use it is a noun meaning "the quality or state of being white; pallor". 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 surface form is compositional: its joined elements remain visible in the modern word. The historical chain includes Old English hwīt and Proto-Indo-European *kweid-. Related English forms include white and whiten. 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.
