Susurrus (suh-SUR-us) – a word that sounds like what it means – is a low, soft whispering, murmuring, or rustling sound. (Plural is susurruses.) Example from The Journal of a Disappointed Man by W.N.P. Barbellion: “They are the susurrus of the breeze before the storm, and you await what is to follow with palpitating heart.”
