Other forms: soughing; soughed; soughs
To sough is to make a moaning or sighing sound. You might inadvertently sough when your math teacher announces another pop quiz.
If you're sick, you may be tempted to lie in bed soughing and feeling sorry for yourself. Or if you're quiet, you might hear the wind sough through the trees outside. Either way, you can hear a soft, murmuring sound. Sough has an Old English root meaning "roar, howl, or whistle," and in 16th-century Scotland it was also used to mean "a vague rumor."
