Three quite different histories are hiding under this tiny word. The industrial sense probably began with a visual metaphor: coal was heated until volatile matter fled, leaving a hard black “core,” perhaps connected with Middle English colke, “core,” and ultimately with words for a hollow or pit; the trail is plausible but not certain. In 1669, English evidence records coke as the furnace fuel we now associate with steelmaking, while the shorter drug sense appeared in American English around 1908 as a clipping of cocaine. Then there is Coke in the refrigerator, shortened from Coca-Cola, the drink introduced in Atlanta in 1886; cola itself comes from a West African tree whose caffeine-rich nuts helped give the beverage its name. So one syllable can point to a furnace, a white powder, or a glass bottle—three unrelated stories sharing the same phonetic coat.
