Just a couple minutes ago. The arrival of "fall", or Autumn.
"The word autumn comes from the ancient Etruscan root autu- and has within it connotations of the passing of the year. It was borrowed by the neighbouring Romans, and became the Latin word autumnus. After the Roman era, the word continued to be used as the Old French word autompne (automne in modern French) or autumpne in Middle English, and was later normalized to the original Latin. In the Medieval period, there are rare examples of its use as early as the 12th century, but by the 16th century, it was in common use".
I'm happy to know these things. If you were asleep at 10:21EDT, this might wake you up.
