'frequently' originates from Latin, specifically the word 'frequentare,' where 'frequent-' meant 'crowded or repeated.' 'Reviewed' comes from the Latin 'revidere,' where 're-' meant 'again' and 'videre' meant 'to see.'

'frequentare' transformed into the Old French 'frequenter,' and eventually became the modern English word 'frequent.' 'Revidere' transformed into the Old French 'reviser,' and eventually became the modern English word 'review.'

Initially, 'frequent' meant 'crowded or repeated,' and 'review' meant 'to see again.' Over time, 'frequently-reviewed' evolved to mean 'examined or assessed often.'
