Why “nundine” is a great word
NUNDINE — [Noun] A market or fair held every eight days, especially in ancient Rome, or the eight-day period between such markets. From Latin nundinae (plural), a clipping of nundinae feriae ("ninth-day festivals"), from novem ("nine") and diēs ("day"), reflecting the inclusive Roman counting of an eight-day interval. Unlike an “emporium”—a permanent temple of trade—or a “week”—a universal seven-day measure—a nundine is both a recurring event and the archaic rhythm it creates. It is the dust rising from cattle pens on the Field of Mars, the clink of bronze coin weighed against spelt, and the palpable shift from isolated toil to collective bustle—a calendar measured not by celestial bodies, but by the cyclical hunger for community and exchange.
Etymology
From Latin nundinae (“ninth-days”), a clipped form of nundinae feriae (“ninth-day festivals”), from its observance every eighth day (9 counting inclusively) and from the Latin practice of treating most recurring calendrical days as plurals.
