coke (n.1)

"fuel residue, solid product of the carbonization of coal,"an important substance in metallurgy, 1660s, a northern England dialect word, perhaps a variant of Middle English colke "core (of an apple), heart of an onion" (c. 1400), also "charcoal" (early 15c.), a word of uncertain origin. It seems to have cognates in Old Frisian and Middle Dutch kolk "pothole," Old English -colc, in compounds, "pit, hollow," Swedish dialectal kälk "pith." Perhaps the notion is the "core" of the coal, or "what is left in the pit after a fire."


soft drink, 1909, a popular shortening of the brand name Coca-Cola, perhaps influenced by the earlier slang use of coke for cocaine (another popular early name for the soft drink was dope).
