Today’s word is sempiternal.
The word means eternal and unchanging; everlasting. Its origins are from Late Middle English: from Old French sempiternel or late Latin sempiternalis, from Latin sempiternus, from semper ‘always’ + aeternus ‘eternal’.
But in philosophy there is a distinction between eternal and sempiternal. Eternal implies something that is infinite outside the bounds of time, like God, while sempiternal is a more earthbound way to talk about forever.
“The one thing which we seek with insatiable desire is to forget ourselves, … to lose our sempiternal memory, and to do something without knowing how or why….”– Ralph Waldo Emerson
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
