Kate could hardly remember now the dry rigid pallor of the heat, when the whole earth seemed to crepitate viciously with dry malevolence; like memory gone dry and sterile, hellish. – D. H. Lawrence, The Plumed Serpent, 1926
When she came into the room, shaking rain-pearls from the hem of her black coat, I could feel her excitement–when she was like that the air around her seemed to crepitate as if an electric current were passing through it. – John Banville, Athena, 1995
Crepitate derives from Latin crepitātus, the past participle of crepitāre “to rattle, rustle, chatter,” a frequentative verb from crepāre and having the same meaning. The word entered English in the 17th century and meant “to break wind, fart,” a meaning that crepitāre had in Latin; the word’s politer senses date from the 19th century.
