Forms

interāneus (feminine interānea, neuter interāneum); first/second-declension adjective[1][2] Spellings with ⟨ent-⟩ and ⟨intr-⟩ also occur, the latter by association with intra.[3]

Etymology

It is formed from Latin inter + -āneus.[1][2] The TLL reports two further views: Leumann derived it from a form *intera (“entrails”) matching Ancient Greek ἔντερα (éntera), comparing exenterāre, while Walde and Hofmann compared extrāneus.[3]

Its substantivized plural lives on in Romance: Old French entraignes, Old Italian entragne, Spanish entrañas and Portuguese entranhas.[3]

Earliest recorded meaning

It appears in the 1st century AD in Columella and Scribonius Largus;[3][4] Scribonius uses it as an adjective of an internal abscess (vomica),[5][2] and Columella has the neuter plural for the guts of birds.[3][2]

Semantic evolution

As an adjective it meant “intestinal” or “internal”;[1][5] far more common was the substantivized neuter plural interānea, “the intestines, entrails”, with the singular interāneum for a gut or the rectum in Pliny the Elder.[5][2] The TLL notes that the word belongs mainly to the more popular writers: Vegetius and almost all the Church writers avoid it, except where they follow the old Bible versions, and the Vulgate lacks it.[3]

Medieval Latin kept both uses: the MLW records it for the belly and inner organs and for the inside of the head or chest,[6] and British sources use it of internal pain and, as a plural noun, of the entrails and of interior parts in general.[7]

Timeline

  • c. 47 AD – Scribonius Largus uses the adjective of an internal abscess.[5][4]
  • 23/24–79 AD – Pliny the Elder uses interāneum for a gut and interānea for the entrails.[5][2][4]
  • first half of the 3rd century AD – Solinus has the plural noun.[2][4]
