'frequently-shared' originates from the combination of 'frequently' and 'shared'. 'Frequently' comes from Latin 'frequentia', meaning 'crowded' or 'numerous', and 'shared' comes from Old English 'scearu', meaning 'division'.

'frequentia' transformed into the Old French 'frequent', and eventually became the modern English word 'frequent'. 'Scearu' evolved into the Middle English 'scharen', leading to the modern English 'share'.

Initially, 'frequentia' meant 'crowded', but over time it evolved into its current meaning of 'often'. 'Scearu' meant 'division', which has evolved to mean 'to distribute or use jointly'.
