'frequently-advanced' is a compound word formed from 'frequently' and 'advanced'. 'Frequently' originates from the Latin word 'frequentia', meaning 'crowded' or 'numerous', and 'advanced' comes from the Old French 'avancer', meaning 'to move forward'.

'Frequently' evolved from the Latin 'frequentia' through Old French 'frequent', while 'advanced' transformed from Old French 'avancer' to the modern English 'advance'.

Initially, 'frequently' meant 'crowded', but it evolved to mean 'often'. 'Advanced' originally meant 'to move forward', which has largely remained the same.
