When should you use undulant?

If you’re looking for an adjective that encapsulates the rising and falling of the briny sea, wave hello to undulant. While not an especially common descriptor, it is useful not only for describing the ocean itself, but for everything from rolling hills to a snake’s sinuous movement to a fever that waxes and wanes. The root of undulant is, perhaps unsurprisingly, unda, a Latin word meaning “wave.” Other English words swimming the wake of unda include inundate, “to cover with a flood,” and undulate, “to form or move in waves.”
