Pronunciation

  • UK: /ɪnˈtɛs.tɪ.nəl/, /ˌɪntɛsˈtaɪ.nəl/[1]
  • US: /ɪnˈtɛs.tɪ.nəl/[1]

Etymology

It is borrowed from Medieval Latin intestīnālis,[2][3] from intestīnum (“gut, intestine”),[2][3] the noun use of the neuter of intestīnus (“inward, internal”),[3][4] from intus (“within”),[3][4] which Etymonline traces to Proto-Indo-European *entos, a suffixed form of *en (“in”).[3] The OED compares French intestinal, used by Paré in the 16th century,[2] and Merriam-Webster takes the word as probably borrowed from intestin with the suffix -al,[5][6] as Johnson had derived it from French.[7] The Shorter Oxford treats it as formed from intestine and -al.[8]

Earliest recorded meaning

Of or relating to the intestines, or found in or affecting them: the OED's first record is from 1599, in a translation of Gaebelkhover's Boock of Physicke.[2][9] Etymonline dates the word to the early 15th century,[3] and the Shorter Oxford and Merriam-Webster also place it in the 15th century,[8][5] while Dictionary.com gives 1590–1600.[10]

Semantic evolution

Johnson (1755) defined it as "belonging to the guts", quoting Arbuthnot on the intestinal tube.[7] In zoology it was also used of animals that have an intestine, as opposed to those without one.[2] A rare literary use, recorded before 1861 in Elizabeth Barrett Browning, takes it in the sense of the adjective intestine, internal or civil.[2][9] Merriam-Webster records further figurative uses, of something internal or of something intricately winding like a gut.[5] The jocular intestinal fortitude, courage or "guts", dates from about 1937.[5]
