'define' originates from Latin, specifically the word 'definire,' where 'de-' meant 'completely' and 'finire' meant 'to limit or end.'

'definire' transformed into the Old French word 'definir,' and eventually became the modern English word 'define' through Middle English.

Initially, it meant 'to set boundaries or limits,' but over time it evolved into its current meaning of 'to explain or describe the nature or scope of something.'
