early 15c., cronik, of diseases, "lasting a long time," from Old French chronique and directly from Latin chronicus, from Greek khronikos "of time, concerning time," from khronos "time" (see chrono-). Vague disapproving sense (from 17c.) is from association with diseases and later addictions. Literal sense "pertaining to time" is rare in English. As a popular slang catch-all word for "cannabis," popularized from 1992 by "The Chronic," an album released by rapper Dr. Dre; said to be because it described especially potent marijuana, on the notion of "extreme, severe." Related: Chronical; chronically.
c. 1300, cronicle, "historical account of facts or events in the order of time," from Anglo-French cronicle, from Old French cronique "chronicle" (Modern French chronique), from Latin chronica (neuter plural mistaken for fem. singular), from Greek ta khronika (biblia) "the (books of) annals, chronology," neuter plural of khronikos "of time, concerning time," from khronos "time" (see chrono-).
The ending was modified in Anglo-French, perhaps by influence of article. Old English had cranic "chronicle," cranicwritere "chronicler." The classical -h- was restored in English from 16c. As a one-word form, classical Greek had khronographia "chronicle, yearbook."
