embezzle

Embezzle is a verb that means "To take (money, for example) for one's own use in violation of a trust."

It's etymological history goes through Middle English, embesilen, from Anglo Norman enbesiler, which comes from Old French, en- an intensive prefix and the Old French besillier, to ravage.

When you think about it embezzling is just that, ravaging, since it is taking money for "one's own use in violation of a trust."
