Etymology
the word 'bluing' is a transparent english formation, combining the adjective 'blue' with the nominalizing suffix '-ing'. the core element 'blue' traces back to old english 'blǣwen', a term related to color, itself from proto-germanic 'blēwaz'. the suffix '-ing', from old english '-ing/-ung', is a productive agent for creating nouns that denote materials or results of an action. thus, 'bluing' logically names a substance or process that imparts a blue color, specifically developed in laundry and metalworking contexts to counteract yellowing or for protective oxidation.
