'frequently' originates from Latin, specifically the word 'frequentia,' where 'frequent-' meant 'crowded or repeated.' 'Developed' originates from Old French, specifically the word 'desveloper,' where 'des-' meant 'un-' and 'voloper' meant 'wrap.'

'frequentia' transformed into the Old French word 'frequent,' and eventually became the modern English word 'frequent.' 'Desveloper' transformed into the Middle English word 'developen,' and eventually became the modern English word 'develop.'

Initially, 'frequent' meant 'crowded or repeated,' and this meaning has largely remained the same in modern usage. 'Develop' initially meant 'to unwrap or unfold,' but over time it evolved into its current meaning of 'to grow or expand.'
