Did you know?

If you think that superfluous must mean "extra 'fluous,'" along the pattern of such words as superabsorbent and superabundant, you're 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.

Synonyms
