Did you know?

When you amortize a loan, you "kill it off" gradually by paying it down in installments. This is reflected in the word's etymology. Amortize derives via Middle English and Anglo-French from Vulgar Latin admortire, meaning "to kill." The Latin noun mors ("death") is a root of admortire; it is related to our word murder, and it also gave us a word naming a kind of loan that is usually amortized: mortgage. Amortize carries a different meaning in the field of corporate finance, where it means to depreciate the cost or value of an asset (as, for example, to reduce interest revenue on that asset for tax purposes).
