Did you know?
When you amortize a loan, you figuratively “kill it off” by paying it down in installments, an idea reflected in the etymology of
amortize. The word comes ultimately from a Latin word meaning “to kill” that was formed in part from the Latin noun
mors, meaning “death”; it is related both to
murder and a word naming a kind of loan that is usually amortized:
mortgage. The original use of
amortize dates to the 14th century, when amortizing was about transferring ownership of a property to a
corporation, and especially to an
ecclesiastical corporation—that is, a corporation consisting wholly of clergy. Such land was said to be in
mortmain, which under the
feudal system meant that the property was permanently exempt from a lord’s usual payment collections.
Mortmain is of course another
mors word. Its second syllable comes from Latin
manus, meaning “hand,” the implication being that the property was held in the dead hand of a corporation—a hand incapable of paying out.
