Etymology

Origin of amortize

1375–1425; Middle English amortisen < Anglo-French, Old French amortiss-, long stem of amortir literally, to kill, die < Vulgar Latin *a ( d ) mortīre (derivative of Latin mors, stem mort- death, with ad- ad- ); -ize later replacing -is ( s )-, probably by association with Anglo-Latin a ( d ) mortizāre

Explanation

To amortize is to gradually pay off a debt. A bank will help you amortize a loan so that you can make a monthly payment until you've paid back the entire amount. A simple way to understand the verb amortize is "make monthly payments on a debt." More specifically, to amortize is to pay down the total amount of the loan a little bit at a time, rather than only covering fees or interest on top of the loan amount. Someone whose bank amortizes their car loan makes a payment each month, gradually reducing the total amount they owe. Amortize stems from a Vulgar Latin word meaning "extinguish."
