Unceasing → It is formed from "un-" (meaning not) and "ceas" (from Old English *ceasian*, meaning to cease or stop) and "-ing" (a suffix used to form present participles). The word "unceasing" means not ceasing or never stopping.
Think of 'not' ('un-') stopping ('ceas') — that's why unceasing means something that never stops.
