The word 'frequently' originates from Latin, specifically the word 'frequentare,' where 'frequent-' meant 'crowded' or 'repeatedly.' The word 'passed' comes from Old French 'passer,' meaning 'to go by.'

'Frequently' evolved from the Latin 'frequentare' through Old French 'frequent,' and 'passed' evolved from Old French 'passer' to Middle English 'passen.'

Initially, 'frequently' meant 'crowded' or 'repeatedly,' and 'passed' meant 'to go by.' Over time, 'frequently-passed' came to describe a path often traveled.
