   • To heat something in advance, before its main use: To bring an appliance, device, or cooking surface to a desired temperature before placing food or other items into it. This is a standard step in many cooking and baking processes.

Usage

The verb "preheat" is almost exclusively used in the context of cooking, baking, or technical processes. It is a transitive verb, meaning it requires a direct object (e.g., preheat the oven). It describes a preparatory action.
