'application' originates from Latin, specifically the word 'applicatio,' where 'ap-' meant 'to' and 'plicare' meant 'to fold.'

'applicatio' transformed into the Old French word 'aplicacion,' and eventually became the modern English word 'application' through Middle English.

Initially, it meant 'the act of applying something,' but over time it evolved into its current meanings, including 'a formal request' and 'a software program.'
