Continuing without stopping or pausing; constantly and persistently.
From incessant (from Latin incessans, from in- not + cedere to stop). The -ly makes it an adverb. It literally means 'not stopping.'
The root 'cede' means to stop or yield—so 'incessant' literally means 'won't cede/yield'—it's a word that refuses to surrender or stop!
