If you remember your high school French, or if you've ever strolled down the Rue de Rivoli in Paris, you may have the notion that the English word rue is somehow connected to the French word for "street." In actuality, the French and English words are not related at all. The English rue is originally from the Old English word hrēow, meaning "sorrow." Used as both a noun and, more frequently, a verb, rue is very old, dating back to before the 12th century.
