The generic name may come from Latin capsa, meaning 'box', presumably alluding to the pods; or from the Greek word κάπτω kapto, 'to gulp'.[4][5][6] The name "pepper" comes from the similarity of piquance (spiciness or "heat") of the flavor to that of black pepper, Piper nigrum[dubious – discuss], although there is no botanical relationship with it or with Sichuan pepper. The original term, chilli (now chile in Mexico) came from the Nahuatl word chīlli, denoting a larger Capsicum variety cultivated at least since 3000 BC, as evidenced by remains found in pottery from Puebla and Oaxaca.[7] Different varieties were cultivated in South America, where they are known as ajíes (singular ají), from the Quechua term for Capsicum.[1]
