Middle English, from Old French superflueux, from Latin superfluus, from superfluere, to overflow : super-, super- + fluere, to flow; see bhleu- in Indo-European roots.(American Heritage® Dictionary of the English Language, Fourth Edition)
From Latin superfluus ("superfluous"), from superfluō ("overflow"), from super ("above, over") + fluō ("flow"). Compare mellifluous and fluid, also from Latin. Literally corresponds to overflow, which is from Germanic, rather than Latin. (Wiktionary)
