USAGE
In the context of life insurance， a technical distinction is made between assurance and insurance. Assurance is used of policies under whose terms a payment is guaranteed， either after a fixed term or on the death of the insured person; insurance is the general term， and is used in particular of policies under whose terms a payment would be made only in certain circumstances （e.g. accident or death within a limited period）.
词源
late Middle English (in sense 2)： from Old French， from assurer 'assure'.
