'qualify' originates from Latin, specifically the word 'qualificare,' where 'qualis' meant 'of what kind' and 'facere' meant 'to make.'

'qualificare' transformed into the Old French word 'qualifier,' and eventually became the modern English word 'qualify' through Middle English.

Initially, it meant 'to make of a certain kind,' but over time it evolved into its current meanings of 'to meet requirements' and 'to modify a statement.'
