I was discussing the much-abused business term leverage with a colleague and thought it would be interesting to know when the term as a verb entered popular use as opposed to the physics-related noun.
I can look at ngrams and do basic searches, but since the forms exist as homonyms I don't know of any tools that can distinguish between the two.
When did the word leverage become a commonplace way to describe borrowing to make money, and how much newer is it than the physics term?
