'amortizable' originates from the verb 'amortize,' which comes from the Latin word 'amortizare,' where 'a-' meant 'to' and 'mort-' meant 'death,' referring to the gradual 'killing off' of a debt.

'amortizare' transformed into the Old French word 'amortir,' and eventually became the modern English word 'amortize' through Middle English.

Initially, it meant 'to bring to death,' but over time it evolved into its current meaning of 'gradually paying off a debt or asset.'
