Etymology: The Moon has been measuring time since long before anyone wrote it down. Its name in English traces back to a Proto-Indo-European root "meh₁-", meaning "to measure", and the same root gave the Moon its link to the calendar: the word for "moon" and the word for "month" are the same word in many of the related languages. Latin "mēnsis" (month), Greek "mínas" (month), and Russian "mésjac" (which means both "moon" and "month") all descend from this ancient stem, as does the Old English "mōna". English, then, kept the celestial sense and let the timekeeping sense drift toward separate words, while its sister languages often kept both meanings together. The Old English form "mōna" was inherited through Proto-West Germanic and Proto-Germanic, and it became "mone" in Middle English before settling into the modern spelling. Germanic cousins such as German "Mond", Dutch "maan", and Swedish "måne" all preserve the same root.
