Amortization or amortization is the process of accounting over a time period

The word comes from Middle English amortisen to kill, alienate in mortmain, from Anglo-French amorteser, alteration of amortir, from Vulgar Latin admortire to kill, from Latin ad- + mort-, mors death. Particular instances of the term include:

When used in the context of a home purchase, amortization is the process by which your loan principal decreases over the life of your loan. With each mortgage payment that you make, a portion of your payment is applied towards reducing your principal and another portion of your payment is applied towards paying the interest on the loan. An Amortization table shows this ratio of principal and interest and demonstrates how your loan's principal amount decreases over time.

Amortization is generally known as depreciation of intangible assets of a firm.
