Pronunciation

  • Classical: [apˈpɛn.dɪks][1]
  • Ecclesiastical: [apˈpɛn.diks][1]

Forms

appendix f (genitive appendicis); third declension[1] Paulus' epitome of Festus gives an older form ampendix.[2][3]

Etymology

It is formed from Latin appendō (“to hang on, weigh out”) + -ix.[4][1] The verb is from ad- and pendō,[5] which goes back to Proto-Italic *pend-e/o- (“to hang”) and Proto-Indo-European *(s)pend-e/o- (“to spin”).[6] De Vaan notes that nearly all handbooks regard this root as a variant of *(s)penh₁- (“to spin, weave”).[6]

According to Paulus' epitome of Festus the ancients said ⟨ampendices⟩, “because they hung around”, for what were later called ⟨appendices⟩.[3][2]

Earliest recorded meaning

The OLD's first citation is from Cicero's Hortensius (81–43 BC), which calls the body an appendage of the mind.[4][7]

Semantic evolution

The general sense is anything attached to something larger, an appendage or adjunct;[4] more often it is figurative, an addition or supplement, as in Varro.[2] Apuleius applies it, with play on its origin, to a person who hangs on to another.[4] Pliny the Elder records it as the name of the barberry, whose red berries were called appendices.[4]

The grammarian Nonius defines it as what is fastened to something else, as if hanging from it.[3] English borrowed it in the 1540s for an addition to a document or book; the anatomical sense of a small outgrowth of an organ followed in the 1610s.[5]
