Etymology and origin of the Latin word umbra

History Permalink
Confidence
Uncertain
First attested
Plautus

Pronunciation

  • IPA (Classical): [ˈʊm.bra][1]
  • IPA (Ecclesiastical): [ˈum.bra][1]

Forms

umbra f (genitive umbrae); first declension[1]

Etymology

The origin is uncertain.[2][3] It is generally compared with Lithuanian ùnksna (“shade”) and Lithuanian unksmė̃ (“shade”) and reconstructed as *unksrā-.[2][4] No other word has the cluster *-nksr-, but by comparison with tēmō from *tenksmōn, de Vaan thinks *unksrā- could have become *unsrā-, *unfrā- and then umbra; the only matching root, *wenk- “to bend”, is unlikely in meaning.[2] Wiktionary also mentions an Old Latin *omra from *h₂mr-u-, related to Ancient Greek ἀμαυρός (amaurós, “dim”).[1]

Earliest recorded meaning

De Vaan dates it from Plautus,[2] who uses it of pleasant shade in summer.[4] Köbler dates Plautus c. 250–184 BC.[5]

Semantic evolution

Its first sense was the shadow cast by a body that blocks the sun; it then also meant a shaded outline, the shelter of a tree and the foliage that gives it, and comparative darkness in general.[4] A shadow that always follows a person gave the sense of an uninvited guest brought along by an invited one.[4][6] Figuratively it was protection, as “under the shadow of an alliance”, and the overshadowing fame of a greater person.[4] It also meant a sheltered, private life (opposed to public action), the darkness of night, and the disembodied ghost of the dead; in the plural it was the underworld.[4]

In Christian Latin it was an allegory or prefiguration.[7] It survives in Italian ombra, French ombre and Spanish sombra.[1] English umbra meant a phantom in the 1590s and the shadow of the earth or moon in an eclipse by the 1670s.[6]
