'regularly-renewed' originates from the combination of 'regularly' and 'renewed'. 'Regularly' comes from Latin 'regularis', meaning 'consistent', and 'renewed' comes from Old French 'renovier', meaning 'to make new again'.

'Regularly-renewed' combines the adverb 'regularly' and the past participle 'renewed' to form a compound adjective.

Initially, 'renewed' meant 'to make new again', and 'regularly' meant 'consistently'. Together, they describe something that is consistently made new again.
