From Greek 'chronika' (things relating to time) — a record of events organized by their sequence in time.
A factual written account of important or historical events in the order of their occurrence; to record events in a factual and detailed way.
From Old French 'cronique' (chronicle, historical record), from Medieval Latin 'chronica,' from Greek 'khronika' (annals, records arranged by time), neuter plural of 'khronikos' (of or relating to time), from 'khronos' (time). Greek 'khronos' is of uncertain PIE origin; it may connect to PIE *gher- (to enclose, to grasp) with the sense of time as a span that encompasses events, but this is disputed. The god Chronos (often conflated with Cronus) personified time
The Books of Chronicles in the Bible — originally called 'Paraleipomenon' (things left out) in the Septuagint — received the name 'Chronicles' from the Latin Vulgate translation, where Jerome titled them 'Chronicon.' This biblical usage helped establish 'chronicle' as the standard English word for historical record-keeping.
