Nonprogressive → It is formed from "non-" (meaning not) and "progressive" (from Latin "progressivus", meaning moving forward). The word "nonprogressive" means not moving forward or not advancing.
Think of 'not' ('non-') and 'moving forward' ('progressive') to remember that 'nonprogressive' describes something that does not advance.
