| 词汇 | hour |
| 词根词缀 | 词源： mid-13c., from O.Fr. hore "one-twelfth of a day" (sunrise to sunset), from L. hora "hour, time, season," from Gk. hora "any limited time," from PIE *yor-a-, from base *yer- "year, season" (see year). Greek hora was "a season; 'the season;'" in classical times, sometimes, "a part of the day," such as morning, evening, noon, night. The Greek astronomers borrowed the notion of dividing the day into sections from the Babylonians. The Gk. division of the daytime into 12 equal hours was generally introduced by Hipparchus c.150 B.C.E. (night continued to be divided into four watches), but as the amount of daylight changed throughout the year, the hours were not fixed or of equal length. Equinoctal hours did not become established in Europe until the 4c., and as late as 16c. distinction sometimes was made between temporary (unequal) hours and sidereal (equal) ones. The h- has persisted in this word despite not being pronounced since Roman times. Replaced O.E. tid, lit. "time," and stund "period of time." 词根记忆： n. 小时,锺点;时刻;课时,工作时间The honourable journalist spent an hour on the journey of tour.可敬的新闻记者在观光旅程上花了一个小时. |
