'frequently' originates from Latin, specifically the word 'frequentia,' where 'frequent-' meant 'crowded or repeated.' 'Move' originates from Latin, specifically the word 'movere,' meaning 'to move or set in motion.'

'frequentia' transformed into the Old French word 'frequent,' and eventually became the modern English word 'frequent.' 'Movere' transformed into the Old French word 'movoir,' and eventually became the modern English word 'move.'

Initially, 'frequent' meant 'crowded or repeated,' but over time it evolved into its current meaning of 'happening often.' 'Move' initially meant 'to set in motion,' and this meaning has largely remained the same in modern usage.
