'frequently' originates from Latin, specifically the word 'frequentare,' where 'frequent-' meant 'crowded or repeated.' 'Ship' originates from Old English, specifically the word 'scip,' meaning 'vessel or boat.'

'frequentare' transformed into the French word 'fréquent,' and eventually became the modern English word 'frequent.' 'Scip' evolved into the Middle English word 'ship,' which is used in modern English.

Initially, 'frequent' meant 'crowded or repeated,' and 'ship' meant 'vessel or boat.' Over time, 'frequently-shipped' evolved to describe items sent often.
