Etymology

It is borrowed from Ancient Greek ὥρα (hṓra, “time, season, hour”).[2][1][3] The Greek word is from Proto-Indo-European *yeh₁- (“year, season”), the root of English year.[1][4]

Earliest recorded meaning

It is found from Plautus onwards,[4] in a famous fragment cursing “the man who first discovered the hours and set up a sundial here”.[2]

Semantic evolution

It was a twelfth part of the day between sunrise and sunset, or of the night, so that the hours varied in length with the season.[2][5] It meant a particular hour or a fixed time, as Cicero's “at that very hour I had received your letter”, and the length of an hour, as Terence's “an hour went by while he talked”.[2]

The poets used it of a season of the year, as Horace's god who rules the world with changing seasons, and of the span of life.[2] In Christian Latin the horae were the canonical hours of prayer, and in Medieval Latin it also meant prayer.[4] It survives as Italian ora and Spanish and Portuguese hora, and English hour came from it through Old French about 1200, first for the canonical hours.[1][6]

Timeline

  • c. 250–184 BC – Plautus mentions the hours and the sundial.[2][4]
  • 190–159 BC – Terence uses it of the length of an hour.[2][4]
  • 81–43 BC – Cicero uses it of a particular hour.[2][4]

  • c. 1200 – English hour is recorded.[6]
