When you hearperennial, you probably think ofpeonies rather than pines. The word today typically describes (or, as a noun, refers to) plants that die back seasonally but produce new growth in the spring. But this wasn’t the word’s initial meaning: originally,perennial was equivalent toevergreen, used, as that word is, for plants that remain with us all year. We took this "throughout the year" sense straight from the Romans, whose Latin wordperennis combinedper- ("throughout") with a form ofannus ("year"). The poet Ovid, writing around the beginning of the first millennium, used the Latin word to refer to a "perennial spring" (a water source), and the scholarPliny used it of birds that don't migrate.Perennial retains these same uses today, for streams and occasionally for birds, but the word has long since branched out to encompass several other senses, including "constant" (as in "a perennial bestseller") and "recurring" (as in "the perennial joy of reading Merriam-Webster’s Word of the Day").
