Pronunciation

  • Ecclesiastical: [suˈpɛr.flu.us][1]

Forms

Etymology

It is formed from Latin superfluō (“to overflow”) + -us.[2][3][4]

Earliest recorded meaning

The OLD's earliest citation is from Seneca's Natural Questions, where a vast hidden body of water gives out only as much as is surplus.[2][5]

Semantic evolution

Lewis & Short note it as post-Augustan.[6] The literal sense “overflowing” is found in Pliny the Younger's Panegyric, of rivers over the fields;[6] the usual sense is “more than is needed, unnecessary”.[2][6] Seneca writes that people might have found what was necessary had they not sought the superfluous.[6] The jurists use it for what is left over, such as the surplus when a creditor sells a pledge for more than the debt, and the neuter as a noun for the balance.[2] The neuter plural superflua meant the body's waste in Caelius Aurelianus.[6] The Vulgate's 2 Maccabees calls praying for the dead, in one case, superfluum et vanum, “superfluous and vain”.[6] Medieval Latin added the senses “abundant” and “unfounded, wrongful”.[7] English took it in the early 15th century as superfluous, after the earlier superflue from Old French.[4]

Timeline

  • before 223 AD – Ulpian uses the neuter for the surplus left after a debt is paid.[2][5]

  • 390–406 AD – The Vulgate has superfluum et vanum in 2 Maccabees.[6][5]
