COLLUVIES — [Noun] A repulsive accumulation of filth or waste, or, by extension, a disorderly and contemptible jumble of things. From the Latin colluvies ("accumulated filth, washings"), from colluere ("to wash thoroughly, rinse out"), from com- ("together") and lavere ("to wash"). Unlike "alluvium" (a neutral, geological deposit of silt) or "medley" (a cheerful, deliberate assortment), a colluvies is a foul confluence of the discarded. It is the slick, congealed detritus in a neglected sink trap; the sour, forgotten debris at the back of a refrigerator; the hoarder's room where newspapers merge with mildewed clothes into a single mass of decay. This is the sober testament that what is washed together does not cleanse, but putrefies.
