Derived from Greek "khronikos" (of time), via Latin "chronicus," the word originally emphasized duration. The root "chron"<time> appears in terms like "chronology" and "synchronize." The suffix "-al" forms adjectives, as in "natural" or "cultural." Over time, "chronic" (and its variant "chronical") narrowed to describe persistent conditions, especially in medicine.
