What does amortized mean?
"Amortized" describes something — usually a debt or a business cost — that is being paid off or written down gradually, in regular installments, rather than all at once. When a loan is amortized, each payment covers both interest and part of the principal, so the balance steadily shrinks until it reaches zero at the end of the term. Accountants also use the word for spreading the cost of an intangible asset, such as software or a patent, across the years it benefits the business. The term belongs chiefly to the worlds of finance and bookkeeping, where it signals prudence and systematic planning: costs are matched to the periods they serve instead of distorting a single year's results. Its etymology is strikingly morbid — it descends from Old French "amortir", meaning to kill or deaden, ultimately rooted in Latin "mors", death — so every scheduled payment literally kills off a little more of the debt. Understanding "amortized" helps readers interpret loan statements, corporate earnings reports, and investment analyses with confidence.

The word literally means 'killed' — from the Old French 'amortir', rooted in Latin mors (death) — because each payment slowly kills off the debt.

Etymology of amortized
"Amortized" comes from the verb "amortize", which entered English in the late Middle Ages from Old French "amortir", meaning to kill, deaden, or extinguish. The French term derives from Latin "ad" (to) combined with "mort-", the root of "mors" (death), making the underlying metaphor literal: payments gradually kill off a debt. The same Latin root gives English other mortality-related words such as "mortgage", "mortmain", and "demise". The financial sense of gradually extinguishing a debt was well established by the early modern period and remains the core meaning today.
