What does leftover mean?
Leftover is a common word for something that remains after other portions have been used, removed, or consumed. As a noun, it usually refers to food left after a meal, as in “I packed the leftovers for lunch,” though it can also mean unused materials, merchandise, or an extra person no longer needed. As an adjective, it describes food, ingredients, stock, or other items that remain available: “We made soup from leftover vegetables.” The word is straightforward but useful because it captures the practical idea of a remainder with a practical or commercial value. Its everyday use is especially associated with food, while in broader contexts it can suggest surplus or something that is no longer needed. “Leftovers” is the usual plural when referring to food or several remaining items.
