"Synergy"

       Yahoo joining up with Tumblr to the tune of 1.1 billion dollars has Wall Street types uttering "synergy" when they contemplate the deal. 

       Syn, "together with"; erg, "work" (traced back to Indo-European werg, "to do").   In physics, "erg" is the unit of work in the metric system, and there it is right in the middle of "energy."

       Peculiarly, the name "George" comes from this.  Ge is "earth" from the Greek, and orge another form of "erg," an occupation-derived name:   "earth worker,"  farmer.

       "Orgy" has the same root, and no telling what a "to-do" and how many "ergs" of energy are embedded in that!

       Only question with Yahoo and Tumblr:  How well do their respective elements really "work together with" each other?
