Pronunciation

  • IPA (Classical): [ˈkɔr.tɛks][1]
  • IPA (Ecclesiastical): [ˈkɔr.teks][1]

Forms

cortex m or f (genitive corticis); third declension[1]

Etymology

It is inherited from Proto-Italic *k(o)rt-ek-, from Proto-Indo-European *k(o)rt- (“a cutting”), with the suffix of caudex and frutex.[2] Cognate with Sanskrit कृन्तति (kṛntáti, “cuts”), Lithuanian kir̃sti (“to hew”) and Old High German herdo (“skin”), and related to corium “skin” and scortum.[2][3][4] Wiktionary takes the root as *(s)ker- “to cut”, as in English shear.[1]

Earliest recorded meaning

De Vaan dates it from Cato, who tells how to rub the husks off wheat.[2][3] Köbler dates Cato 234–149 BC.[5]

Semantic evolution

It was the bark of a tree and in particular cork, used for floats and beehives, and so a symbol of lightness.[3][6] It also meant the rind of fruit, the husk of grain, the shell of an egg or turtle, and any outer layer.[3][6] It was usually masculine, but Lucretius and Virgil make it feminine.[3]

In medieval British Latin it could mean the surface or literal meaning of a text, as opposed to its kernel.[7] English cortex was borrowed in the 1650s, and the brain's cortex is from 1741.[8]
