Pronunciation

  • Classical: [ˈiː.rɪs][1]
  • Ecclesiastical: [ˈiː.ris][1]

Forms

īris f (genitive īris or īridis); third declension[1]

Etymology

It is borrowed from Ancient Greek ἶρις (îris, “rainbow; iris plant”).[2][1][3] The Greek word is of uncertain origin; it has traditionally been traced to Proto-Indo-European *wei- (“to bend, turn”).[4][3]

The Romans already connected the plant with the rainbow: Pliny the Elder says it is named for its many colours, like the rainbow's.[2] Servius derived the goddess's name from Ancient Greek ἔρις (éris, “strife”), because she was sent to sow discord.[5]

Earliest recorded meaning

Its earliest occurrence is in Cato's treatise on agriculture, which uses dried, crushed iris in a recipe, the orris root.[2][3]

Semantic evolution

In poetry it is the name of Iris, the messenger of the gods and goddess of the rainbow, whom Juno sends down from heaven in Virgil and Ovid.[2][6] Manilius and Seneca use the goddess as a personification of the rainbow itself,[2] and the word means simply “rainbow” in Seneca's Natural Questions, Apuleius and the Vulgate, where a rainbow surrounds the throne in the Apocalypse.[6][7] Pliny the Elder also uses it for an iridescent stone, perhaps a prismatic rock crystal, which throws the colours of the rainbow on a wall.[2][6]

As the name of the plant and of its fragrant root it was common in medicine and perfumery, in Celsus, Columella and Pliny.[2] Medieval writers kept the senses “rainbow” and “iridescent stone”;[8] Bede calls the rainbow a sign of God's reconciliation.[8] English took iris as the name of the plant in the late 14th century and for the membrane of the eye in the 15th.[4]
