שעון (sha'on) — clock; watch
Etymology
The ancient Hebrew Bible contains no sub-daily time units beyond morning, noon, evening, and the three or four night watches. Ancient Israelites appear to have lacked timekeeping instruments, though one obscure passage in Isaiah (38:8) — concerning the shadow moving on "the steps (ma'alot) of Ahaz" — may refer to a sundial that King Ahaz brought back from Assyria in the 8th century BCE, as archaeologist-general Yigael Yadin argued.
The division of day and night into twelve hours each was adopted during the Babylonian Exile, together with the Aramaic word שַׁעְתָּא (sha'ta) for an hour, which became Hebrew שָׁעָה (sha'ah). The Talmud Bavli (Sanhedrin 38b) provides the earliest explicit evidence: "The day consists of twelve hours." These hours were measured in everyday life by a sundial (mentioned in Mishnah Eduyot 3:8 as "even sha'ot," the hours stone), and their length varied with the season — longer in summer, shorter in winter. Medieval scholars called these "temporal hours" (sha'ot zmaniyot), distinguishing them from "equal hours" (sha'ot shavot) used in astronomical calculations.
The Talmud also used many informal time measures: the time to eat a fixed amount of bread, the time to walk a certain distance, the duration of uttering a word — "rega" (moment), which the Jerusalem Talmud defines as the time it takes to pronounce the word, or alternatively 1/56,848 of an hour (Berakhot 5:1). The equal hour was divided not into minutes but into 1,080 "parts" (chalakim), each containing 76 "moments" (rega'im). To measure equal hours, Jews adopted the Greek water clock (clepsydra), called "chalaf sedra" in the midrash (Genesis Rabbah, 6th century), from the Greek klepsydra ("water thief"), and "urlogin" in the Jerusalem Talmud (Rosh HaShanah 57b), from Greek hōrologion ("hour-teller").
As mechanical clocks appeared in European church towers in the 13th century, Hebrew writers coined or adapted terms: Rabbi Abraham bar Hiyya (1133) used "sha'ot" (hours); Rabbi Abraham Bibago (15th c.) coined "kli ha-sha'ot" (vessel of hours); David Ganz (16th c.) used "moreh sha'ot" (hours-shower); some used the unwieldy "kli moreh sha'ot." The sub-hour divisions of minutes (דַּקּוֹת) and seconds (שְׁנִיּוֹת) were borrowed from the system medieval astronomers used to divide celestial degrees, as Abraham Ibn Ezra explained in his 12th-century Reshit Chokhmah: "every degree has sixty primary minutes (dikim) and every minute sixty seconds, and so on to twenty." The word דַּק (minute) was coined there under Arabic influence (daqiqa).
The Industrial Revolution made clocks small, cheap, and precise. The acceleration of modern life demanded a single short word. The competing candidates — מוֹרֶה (teller), שָׁעָה (hour), and אוּרְלוֹגִי (from the Greek) — all fell short. The winner was שַׁעוֹן, coined by Rabbi Yechiel Michel Pines in the Land of Israel at the turn of the 20th century. The word is built on שָׁעָה with the instrumental suffix -וֹן: "the hour-thing." Its first documented appearance in print is in the journal Ha-Shiloach in 1903: "The clock (ha-sha'on) rang the first hour." The word arrived just in time: wristwatches became popular during World War I, and by then שעון was already in place. Simultaneously, the word דַּקּוֹת (minutes) replaced the earlier "dikim."
