Chili or chilli is a term used to refer to a variety of spices that are derived from the fruit of the Capsicum plant. These spices can be hot or mild, depending on the type of pepper they come from. In some countries, such as India and Pakistan, it refers specifically to the powder made from dried chili peppers, while in other parts of the world, including Mexico and the United States, it is used interchangeably with "chile" or "chilli pepper," which refers to the plant itself.
