'chronological' originates from Greek, specifically the word 'khronologikos,' where 'khronos' meant 'time' and 'logos' meant 'study or discourse.'

'khronologikos' transformed into the Latin word 'chronologicus,' and eventually became the modern English word 'chronological' through Middle English.

Initially, it meant 'pertaining to the study of time,' but over time it evolved into its current meaning of 'arranged in the order of time.'
