Origin of horologium

First recorded in 1350–1400; from Latin hōrologium, from Greek hōrológion, equivalent to hōrológ(os) “timeteller” (from hōro-, combining form of hṓra “year, season, time of day, right time” + -log-, variant stem of légein “to count, recount, say, speak, tell” + -os adjective suffix) + -ion diminutive suffix; hour, logos ( def. )
