'frequently-offered' originates from the combination of 'frequently' and 'offered', where 'frequently' comes from Latin 'frequentia' meaning 'crowded' and 'offered' from Latin 'offerre' meaning 'to present'.

'frequently' changed from the Latin word 'frequentia' and 'offered' from 'offerre', eventually becoming the modern English phrase 'frequently-offered'.

Initially, 'frequently' meant 'crowded' and 'offered' meant 'to present', but over time they evolved into their current meanings of 'often' and 'provided'.
