Pronunciation

  • Classical: [ˈjuː.bɪ.ɫoː][1]
  • Ecclesiastical: [ˈjuː.bi.lo][1]

Forms

iūbilō (present infinitive iūbilāre, perfect active iūbilāvī, supine iūbilātum); first conjugation[1]

Etymology

It is probably formed from Proto-Italic *iū (“exclamation of joy”), with the verbal ending ⟨-bilāre⟩ of sībilō (“to whistle”).[2][3] De Vaan finds enough evidence to reconstruct an exclamation Proto-Indo-European *iū, though it is plainly onomatopoeic.[2][1] The OLD compares the interjection iō.[3]

Cognate with Ancient Greek ἰύ (iú, “interjection of amazement”), ἰυγή (iugḗ, “crying”) and ἰύζω (iúzō, “to cry aloud”), Middle High German jū (“exclamation of joy”) and jūchezen, Dutch juichen, Old Norse ýla and English yowl (“to howl”).[2]

Earliest recorded meaning

De Vaan dates it from Varro,[2] who lists quiritare and iubilare together as kinds of crying out, and quotes a comic line in which someone asks “who is hallooing me?” (quis me iubilat?).[4][5]

Semantic evolution

It was first a rustic word for whooping and shouting aloud, used also of birds (the kite) screeching,[5] and with an object, for calling out to someone.[3][4]

In the Vulgate it became the verb for shouting for joy to God (iubilate Deo in the Psalms),[4][5] and Ecclesiastical Latin uses it for rejoicing and singing joyfully.[6] Medieval Latin kept this sense of jubilant crying and praise of God or a ruler, and used it for singing out a hymn, and once even for wailing in grief.[7] From its participle came English jubilate in the 1640s.[8]

Timeline

  • 116–27 BC – Varro lists it among the words for crying out.[5][9]

  • 390–406 AD – The Vulgate uses it for shouting to God in joy.[5][9]
