Forms

iūbilaeus m (genitive iūbilaeī); second declension; also an adjective in annus iūbilaeus.[1][2] The manuscripts and editions also have iobeleus, iubeleus and iubilaeus, varying between one another.[3] A neuter iūbilaeum “jubilee time” is found in the Vulgate.[4]

Etymology

It is borrowed from Ancient Greek ἰωβηλαῖος (iōbēlaîos),[1] from Biblical Hebrew יובל (jōbēl).[1][4][3][5] Etymonline gives the Hebrew word the older meanings “ram's horn” and “ram”, since the jubilee was announced with a ram's horn.[6] The spellings with ⟨-bil-⟩ come from association with the unrelated verb iūbilō “to shout with joy”.[6][3]

Isidore of Seville already calls it a Hebrew word,[3] which he interprets as “the gift of remission”.[7][8]

Earliest recorded meaning

It is a Christian word: the TLL cites it from Hilary of Poitiers, Ambrose and Jerome,[3] and Köbler's first source is the Vulgate,[5] where annus iubilaeus is the Jewish year of jubilee, every fiftieth year, when slaves were freed and land returned to its former owners.[1][2]

Semantic evolution

In Late Latin it names the jubilee year of the Law of Moses, both as a noun and as an adjective with annus.[1][4][2] The Christian poet Arator uses its first syllable short.[4][1]

In Medieval Latin it kept the Old Testament sense,[9][8] and it was used of the Catholic Holy Year, in which the pope granted remission of penalties: a Hungarian record speaks of a bishop who went to Rome “in the jubilee year, the year of the Lord 1300”.[10] Niermeyer also records the sense “a man of fifty”.[9] English took the word from Old French in the late 14th century.[6]

Timeline

  • c. 315–367/368 AD – Hilary of Poitiers uses it in his commentary on Psalm 118.[3][5]
  • 390–406 AD – The Vulgate calls the fiftieth year annus iubilaeus.[4][2][5]
  • c. 560–636 AD – Isidore of Seville explains it as a Hebrew word.[3][8][5]
  • 1300 – A Hungarian record uses it for the Holy Year in Rome.[10]
  • late 14th century – English borrows it, through Old French, as jubilee.[6]
