Stealthier is formed from "stealth" (from Old English *stielþ*, meaning secret or hidden) and the suffix "-ier" (indicating a comparative degree). The word "stealthier" means more secretive or hidden compared to something else.
Think of 'stealth' as being 'hidden' or 'secret' — the '-ier' shows that it is more so. So, when something is stealthier, it is more hidden than before.
