'frequently-proposed' originates from the combination of 'frequently,' derived from Latin 'frequentia,' meaning 'a crowd or multitude,' and 'proposed,' from Latin 'proponere,' meaning 'to put forward.'

'frequentia' transformed into the Old French 'frequent,' and 'proponere' became 'proposer' in Old French, eventually forming the modern English 'frequently-proposed.'

Initially, 'frequentia' meant 'a crowd,' and 'proponere' meant 'to put forward.' Over time, 'frequently-proposed' evolved to mean 'suggested often.'
