reheat

Imagine you've made a pot of chili, enjoyed it for dinner, and saved some for later. To reheat that chili is to warm it up again so it is hot and ready to eat. This is the most common use of the word, and it is often used for leftovers, coffee, soup, or any food that has gone cold. It can also be used in a figurative way. If someone reheats an old argument or debate, they bring it up again after it had quieted down. In both cases, the idea is the same: something cools off, and then someone brings the heat back.

To reheat literally means to apply heat again to something that has become cool. This is most commonly used in the kitchen when bringing leftovers back to a palatable temperature. For example, "She reheated the pizza in the oven," or "The chef carefully reheated the sauce before serving it."

However, the word often extends into figurative territory to describe reviving something that has faded or lost its momentum. A news outlet might reheat an old story by revisiting it with fresh details, or a person might reheat a dormant dispute by mentioning old grievances. The core idea is restoration—bringing something back to a previous state of activity, intensity, or relevance. It implies that the subject was once "hot" (literally or metaphorically), was allowed to cool down, and is now being brought back to life with new effort.

Whether you are warming up dinner or bringing a forgotten topic back to the table, "reheat" signifies the act of restoring something to its former warmth and vitality.
