Etymology
Origin of incessant
First recorded in 1425–75; late Middle English incessaunte, from Late Latin incessant-, equivalent to Latin in- negative prefix + cessant- (stem of cessāns ), present participle of cessāre “to stop work”; see in- 3, cease, -ant
Explanation
Something incessant continues without interruption. When you're on a cross-country flight, it's tough to tolerate the incessant crying of a baby. In Latin, cessare means "to stop," so when you add the negative prefix in-, you get a word meaning "never stopping." A near synonym is continual, but something incessant is more relentless; ceaseless is a closer synonym. It's rare to find incessant used in a positive way. Even incessant sunshine would grow boring.
