Origins of "finance"

As an engineer, I've always been fascinated as colleagues go off to other jobs, presumably better paying, in the large, nebulous field of "finance." And so yesterday I took a look at my dictionaries to see what the origins of the word might be.

1990 dictionary: from the Old French "finans," or "ransom."

Noah Webster's 1828: from Latin and French words meaning a "fine."

Hmmmm.....I may yet decide to start demanding ransoms or fines for a living, or I may realize that modern word usage isn't completely hostage to etamology. Hopefully the latter, but I figured my "vast readership" might enjoy the irony of one of our most respected (and disrespected) professions having its root in feudal hostage-taking.
