going on without stopping
"the ceaseless thunder of surf"
"in constant pain"
"night and day we live with the incessant noise of the city"
"the never-ending search for happiness"
"the perpetual struggle to maintain standards in a democracy"
"man's unceasing warfare with drought and isolation"
"unremitting demands of hunger"
The noise of the wind was an incessant metallic whispering.

Daodu was an incessant conversationalist.
