chocoholic

the word is a modern playful formation, a blend modeled directly on the pattern of "alcoholic." the first element, "choco," is a straightforward truncation of "chocolate," a borrowing with a long history tracing back to the nahuatl word for a bitter drink. the second element, "-holic," was abstracted in the mid-20th century from "alcoholic" to function as a productive suffix meaning "addicted to" or "compulsively devoted to." thus, "chocoholic" humorously applies the logic of substance addiction to a passionate fondness for chocolate, creating a vivid and widely understood colloquial term.

Structure: choco (chocolate) + holic (addicted to) "choco" is a clipping of the english word "chocolate", ultimately from nahuatl 'xocolātl'. "holic" is a slang suffix extracted from the word "alcoholic", which itself derives from the arabic 'al-kuḥl' (the kohl) via medieval latin, referring to a fine powder, later to distilled spirits.
