köken: From Middle High German abfal, abefal, equivalent to ab- (“from”) + Fall (“fall”). Cognate with German Low German Offall, Dutch afval, English offal, Swedish avfall. Compare typologically Bulgarian отпадък (otpadǎk), Czech otpad, Serbo-Croatian отпад (< Proto-Slavic *otъpadъ < *otъ + *padati). Also compare French déchet (<< Latin dēcidō < dē- + cadō).
köken: According to several sources summarized in Eren (1999), from Ottoman Turkish گوبره (göbre, gübre) (whence modern Turkish gübre), ultimately from Greek κοπριά (kopriá). However, compare also Karakhanid کُڤْرا (küwre).
köken: From Middle Dutch afval, shortening of slachtafval (“that which fell off from slaughtered meat.”), equivalent to af + val or a deverbal from afvallen. Compare English offal.
köken: From Proto-Italic *fūje-, from earlier *θūje, modeled on Proto-Indo-European *dʰuh₂-yé-ti, from Proto-Indo-European *dʰewh₂-. See also Latin furvus (“dark, swarthy”), fūmus (“smoke”) and fūlīgō (“soot”).
From Old Galician-Portuguese [Term?], equivalent to estro + -ume, from estrar, from estrado, from Latin strātum. Related to English strew. Alternatively from a Vulgar Latin *strumen, from Latin strāmen, related to sternō and strātum.
