caudex

Etymology and origin of the Latin word caudex

History Permalink
Confidence
Uncertain
First attested
Plautus

Pronunciation

  • IPA (Classical): [ˈkau̯.dɛks][1]
  • IPA (Ecclesiastical): [ˈkaːu̯.deks][1]

Forms

caudex m (genitive caudicis); third declension[1] The later form cōdex is used mainly for “book”.[2][1]

Etymology

The origin is uncertain.[2][1] De Vaan thinks it cannot be a recent derivative of cūdō “to beat” and takes it from the stem of cauda “tail”, reconstructing Proto-Italic *kaud-ek-, from Proto-Indo-European *keh₂u-d- (“cleft, split”).[2] Wiktionary and the OLD connect it with cūdō, both from a root meaning “to beat, hew”, so that it was first “what is hewn”.[1][3] Lewis and Short call it doubtful.[4]

Earliest recorded meaning

It is found from Plautus onwards, who has its derivative caudicalis.[2][5]

Semantic evolution

It meant the trunk or stem of a tree, as Virgil's cut trunks from which an olive root is pushed out,[3] and Terence used it as an insult, “blockhead”.[6][7] Wooden tablets for writing were cut from it, so it came to mean a book of tablets, a notebook or account book, as when Cato had the book with his speech brought out.[3]

It was also the cognomen of Appius Claudius Caudex, consul in 264 BC, who according to Seneca was the first to persuade the Romans to take to ships.[8][4] In the form codex it came to mean a book and a code of laws, and English code came from it through Old French about 1300.[9]
