I came across the word ‘sough’ (pronounced suhf) recently. I wrote it down and looked it up immediately.
From a definition page:
verb: sough; 3rd person present: soughs; past tense: soughed; past participle: soughed; gerund or present participle: soughing
- (of the wind in trees, the sea, etc.) make a moaning, whistling, or rushing sound.”the soughing of the wind in the canopy of branches”
noun: sough; plural noun: soughs
2. a moaning, whistling, or rushing sound as made by the wind in the trees or the sea.
From Middle English swoughen, from Old English swōgan; akin to Goth gaswogjan to groan, Lithuanian svagėti to sound.
Example from literature:
“The sough of the wind and the fleeing cloud of night was all they saw or heard.”– The Dew of Their Youth by S. R. Crockett
