Etymology
Origin of chronological
First recorded in 1605–15; chronolog(y) + -ical
Explanation
If you’re making a list of all your teachers in the order you had them, from kindergarten right up to the present, you’re listing them in chronological order. Chronological is the order in which things actually happened. Chronological doesn’t allow for time traveling or flashbacks. If you’re making a documentary of events leading up to World War II and you start in the early 1900s and end at the outbreak of the war, in 1939, that’s chronological. Reverse chronological order means giving the most recent event first, and going backwards from there. Chronological includes the useful Greek root khronos, "time."
