'segment' originates from Latin, specifically the word 'segmentum,' where 'se-' meant 'apart' and 'mentum' meant 'a means or result of an action.'

'segmentum' transformed into the Old French word 'segment,' and eventually became the modern English word 'segment' through Middle English.

Initially, it meant 'a part cut off or separated,' but over time it evolved into its current meaning of 'a distinct part or section.'
