Nitpickier → It is formed from "nitpick" (a compound of "nit" (meaning the egg of a louse) and "pick" (meaning to select or choose)) and the comparative suffix "-ier" (meaning more). The word "nitpickier" describes someone who is more inclined to focus on trivial details or minor errors, akin to picking at nits.
Think of someone who is more focused on 'selecting' ('pick') tiny details ('nit') — that's why nitpickier means someone who is more particular about small things.
