Did you know? 
     If you think that "superfluous" must mean "extra 'fluous,'" 
along the pattern of such words as "superabsorbent" 
and "superabundant," you're actually not far off. "Superfluous" 
comes from the Latin adjective "superfluus," meaning 
literally "running over" or "overflowing." "Superfluus," in 
turn, derives from the combination of the prefix "super-" 
(meaning "over" or "more") and "fluere," "to flow."  ("Fluere" 
also gave us "fluid," "fluent," and "influence," among others.)  
Since its first appearance in English in the 15th 
century, "superfluous" has referred to an "overflowing" of some 
supply, as of time or words, which hearkens back to its Latin 
origins.
