"Crumbs" refers to small pieces or fragments of food that are often left over after eating. These tiny bits can come from various types of food, such as bread, cookies, or pastries. Crumbs can accumulate on surfaces like tables or plates and are sometimes used in cooking, such as in breading or as a topping for dishes. In a broader context, "crumbs" can also symbolize small amounts of something valuable or desirable. For example, in discussions about wealth or opportunity, people might refer to "crumbs" to describe the minimal benefits that some individuals receive compared to others.
