Chili pepper (from Nahuatl chilli), also known as, or spelled, chilli pepper, chilli, chillie, chili, and chile, is the fruit of the plants from the genus Capsicum, members of the nightshade family, Solanaceae.
Although botanically speaking, the fruit of capsicums are berries, the peppers are considered as vegetables or spices for culinary purposes. Depending on flavor intensity and fleshiness, their culinary use varies from use as a vegetable (e.g., bell pepper) to use as a spice (e.g., cayenne pepper).
Chili peppers originated in the Americas. Their cultivars are now grown around the world, because they are widely used as food and as medicine.
