'regularly-authorized' originates from the combination of 'regularly' and 'authorized'. 'Regularly' comes from Latin 'regularis', meaning 'consistent', and 'authorized' comes from Latin 'auctorizare', meaning 'to give authority'.

'Regularly' evolved from the Latin 'regularis' through Old French 'regulier', and 'authorized' evolved from Latin 'auctorizare' through Old French 'autoriser'.

Initially, 'regularly' meant 'in a consistent manner', and 'authorized' meant 'given authority'. The combined term 'regularly-authorized' maintains these meanings, indicating consistent official approval.
