Microscopic → It is formed from "micro-" (from Greek "mikros", meaning small) and "scopic" (from Greek "skopein", meaning to look or examine). The word "microscopic" refers to something that is so small it can only be seen with a microscope, emphasizing the act of looking at small things.
Think of 'small' ('micro-') and 'looking' ('skopein') to remember that 'microscopic' means something that is too small to see without a special tool.
