köken: From Old Anatolian Turkish [script needed] (emcek). Ultimately a derivation of Proto-Turkic *em- (“to suck”), whence also əmmək (“to suck”) and əmizdirmək (“to breastfeed”). Cognate with Turkish emcik (“breast”), Turkmen emjek (“breast, udder”), Uzbek emchak (“udder”), Uyghur ئەمچەك (emchek, “breast, udder”), Chuvash ӗм (ĕm, “to suck”), etc.
köken: From Proto-Turkic *emček (“breast; nipple”), from *em-. Cognate with Bashkir имсәк (imsək), Kyrgyz эмчек (emcek), Crimean Tatar emçek, Uzbek emchak, Turkmen emjek, etc.
köken: Deverbal from bicar. According to folk etymology, the coffee sense is an acronym of Beba Isto Com Açúcar (“drink this with sugar”). This etymology appears to have come from a 1998 text, however, and the term most likely came about as a way to differentiate between machine coffee and coffeepot coffee.
Unknown. Probably an expressive creation. Attempts have been made to link it to Latin gurgulio or gurgullus, though this is uncertain. Compare Aromanian gurgulj.
