'diligence' originates from Latin, specifically the word 'diligentia,' where 'diligere' meant 'to value highly or love.'

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

Initially, it meant 'careful attention or love,' but over time it evolved into its current meaning of 'careful and persistent work or effort.'
