Why this word is great

HOROLOGION — [Noun] A liturgical book containing the canonical hours, the daily cycle of prayers for the Eastern Orthodox and Eastern Catholic churches. From Byzantine Greek ὡρολόγιον (hōrológion, "book of hours"), from Ancient Greek ὥρα (hṓra, "hour, time period") + λόγιον (lógion, "record, measuring device"). Unlike the Roman "breviary" (which parcels devotion into a compact, portable manual) or the "menologion" (which chronicles saints' lives by the month), the horologion is the fixed, cyclical architecture of the day itself. It is the deep, resonant chant that greets the predawn darkness, the whispered psalms marking the sun's zenith, and the final, fading hymn released into the gathering twilight—a meticulous ordering of time against time’s own entropy.

noun

A liturgical book containing the daily offices of the Eastern Orthodox and Catholic churches.“The Orthodox horologion is roughly equivalent to the Catholic breviary.”
