Etymology tree
inherited borrowed derived
Latin ieiunus
English jejune

Pronunciation

  • IPA: /d͡ʒəˈdʒuːn/, /d͡ʒiˈdʒuːn/[1]

Etymology

It is borrowed from Latin iēiūnus (“fasting, hungry; meagre, barren”),[2][3][4][5][6] a word of obscure origin.[4] De Vaan, cited by Etymonline, links it to a root meaning “to worship”, from the custom of making the first sacrifice of the day on an empty stomach.[4]

Earliest recorded meaning

Dull, flat, insipid (1615).[7][3][4]

Semantic evolution

The literal Latin sense “fasting, hungry” was used briefly in English (before 1619) and is obsolete.[7] From 1646 the word meant lacking nourishment or substance,[7][5] as of land or food.[7] The sense “puerile, childish, naive” dates from 1898;[7] the OED suggests it may come from the mistaken belief that the word is related to Latin juvenis “young”.[7]
