Introduction
The PIE word *yóh₁r̥: "year" becomes both the native English "year" and also the Latinate "hour". Fascinatingly, Greek ὥρᾱ hṓrā (whence the Latin) is also borrowed, post-Alexander, into Classical Sanskrit along with the Hellenistic-Babylonian astronomy/astrology, eventually giving such descendants as Thai โหร hǒon: "astrologer, prophet, magician"!
