Sough is a verb that means to rustle, moan or sigh.
Sough comes to us from Middle English. It looks and sounds a lot like the word ‘sigh,’ but sough is a broader word that may refer either to the sound coming from the lungs of an exasperated person or the wind rustling through trees.
As a kid I always loved the sounds of our rural neighborhood. In particular, the way the wind would sough through the trees always felt lovely.
