Etymology
the word deductible is built from the latin verb deducere, meaning "to lead down or away." the prefix de- signifies removal or reversal, while the root ducere means "to lead." the suffix -ibilis (english -ible) was added to form an adjective meaning "that which can be led away or taken off." this literal sense of "capable of being subtracted" evolved into its modern financial and insurance meanings, where it describes an amount that can or must be taken away from a total sum or payment.
