Pronunciation

  • Classical: [ˈwɪs.kũː][1]
  • Ecclesiastical: [ˈvis.kum][1]

Forms

viscum n (genitive viscī); second declension[1] Plautus has the masculine viscus.[2][3]

Etymology

It is perhaps inherited from Proto-Italic *wisko-.[3] De Vaan regards it as either a Proto-Indo-European word or a European loanword for mistletoe or another fruit-bearing tree; the original form may have been *wiks-, with metathesis in Latin, or *wiKsk-, with the middle cluster simplified differently in each language.[3] Wiktionary gives Proto-Indo-European *weyḱs- with a question mark.[1] Cognate with Ancient Greek ἰξός (ixós, “mistletoe; birdlime”), Old High German wīhsela (“morello cherry”) and Proto-Slavic *višьňa.[3][1]

Earliest recorded meaning

De Vaan dates it from Plautus,[3] who uses the masculine viscus for birdlime in a figure: in the Bacchides flattery is viscus merus, pure birdlime.[2][4]

Semantic evolution

Cato gives a recipe to be boiled until as thick as birdlime,[2] and Cicero says that a small creature sticks in the wax of the ear as in birdlime.[2] Virgil counts trapping birds with lime among the early inventions, and in the Aeneid describes mistletoe green with new leaves in winter on a tree that did not sow it.[2] Pliny the Elder describes the plant on oaks and other trees, and Columella and Celsus use it in medicine.[2][4] It was also applied to other sticky substances, as pitch in Juvenal.[2] Medieval writers used it of mistletoe, especially that of the oak, in medicine.[5]

Timeline

  • c. 250–184 BC – Plautus uses it for birdlime, figuratively.[3][2][6]
  • 234–149 BC – Cato uses it as a measure of thickness.[2][6]
  • 70–19 BC – Virgil uses it of birdlime and of the mistletoe.[2][6]
  • 23/24–79 AD – Pliny the Elder describes the plant.[2][6]

Meanings

Noun

  1. Mistletoe, a plant parasitic on trees.[2][7]
  2. Birdlime made from mistletoe berries; figuratively, a snare.[2][7]
  3. Any other sticky substance, such as pitch.[2][8]

Usage notes

The OLD's second viscum is only a variant of the unrelated viscus “internal organ”.[2]
