Addendum on "Influenza"

       The real "working" part of that word influenza is what we call it for short, "flu."

       Again as might be figured out, it comes from a root meaning "flow," suggestive of water running.  It's not only water that moves, as we might say, "fluently," "fluidly," but also what happens in "influence," whether by the stars (see yesterday's post), or, perhaps the way the disease moves not only within the body, seemingly everywhere to make itself felt, or, moves from person to person so easily -- it virtually flows -- and readily exerts its influence.
