Did You Know?
Although it probably makes you think more of snakes than head colds, sinuous is etymologically more like sinus than serpent. Sinuous and sinus both derive from the Latin noun sinus, which means "curve, fold, or hollow." Other sinus descendents include insinuate ("to impart or suggest in an artful or indirect way") and two terms you might remember from math class: sine and cosine. In English, sinus is the oldest of these words; it entered the language in the 1400s. Insinuate appeared next, in 1529, and was followed by sinuous (1578), sine (1593), and cosine (1635). Serpent, by the way, entered English in the 13th century and comes from the Latin verb serpere, meaning "to creep."
