Pronunciation

  • UK: /mɪˈlɛn.ɪ.əl/[1]
  • US: /məˈlɛn.i.əl/[1]

Etymology

It is formed from English millennium + -al, from the stem of millennium;[2][3][4][5][6] the OED describes it as a borrowing of New Latin millennium combined with the English suffix.[3] The Latin noun was formed from mīlle (“thousand”) and annus (“year”) on the model of biennium and triennium.[2] The OED compares the earlier millenary and millenarian.[3]

Earliest recorded meaning

Relating to the millennium of Christian prophecy, the thousand-year reign of Christ: 1660, in H. More's Explanation of the Grand Mystery of Godliness.[3][5] Etymonline dates it to the 1660s and Merriam-Webster to 1664.[2][4]

Semantic evolution

Johnson (1755) knew it only in the religious sense, quoting Burnet on "the millennial happiness".[7] From 1807, in J. Barlow's Columbiad, it also meant lasting a thousand years or thousands of years.[3][2] As a noun it first meant a thousandth anniversary or its celebration, from 1896,[3][2][4] a sense the OED now marks as obsolete and rare.[3] From 1983 the adjective was used of the years around the end of the 20th century, especially of things made to mark the year 2000.[3] As a name for the generation coming of age around 2000, it is first recorded in W. Strauss and N. Howe's Generations (1991);[3][2] the OED defines them as born between the early 1980s and the mid 1990s, Merriam-Webster as born in the 1980s or 1990s.[3][4] Collins describes them as the generation that reached adulthood around 2000.[8]
