Pronunciation

  • Classical: [ɪn.tɛsˈtiː.nũː][1]
  • Ecclesiastical: [in.tesˈtiː.num][1]

Forms

intestīnum n (genitive intestīnī); second declension[1] Varro has it as a masculine in the Menippean satires, and Petronius as a feminine.[2][3]

Etymology

It is from Latin intestīnus (“internal”), its neuter used as a noun.[2][4] De Vaan notes that the noun is found earlier (Plautus) than the adjective (Varro), and that the two senses point to an adjective first meaning “internal”.[5] He reconstructs Proto-Italic *n̥ter-sto- (“internal”): following Leumann, a compound of inter (“between”) with the root of stō (“to stand”), with /rst/ reduced to /st/;[5] Walde and Hofmann's derivation from Proto-Indo-European *entos (“inside”) he thinks possible but less likely.[5]

Earliest recorded meaning

De Vaan and Köbler record it from Plautus.[5][6] In the Casina a character says his guts have long been rumbling with hunger: mihi ieiunitate iam dudum intestina murmurant.[2][3]

Semantic evolution

In the plural it is the intestines or guts, as in Plautus and in Cicero's letters, where he suffers badly from his bowels.[2][3] In the singular Lucretius uses it for the alimentary canal,[2][5] Celsus for the small intestine, and Nepos and Scribonius Largus for the rectum.[3] Medieval medical writers in Britain name the separate parts of the intestine with it, and also use it of animals' offal.[7] English took it as intestine in the early 15th century, from Old French or directly from Latin.[4]
