The onion (Allium cepa) is a biennial plant grown as a vegetable and is the most widely cultivated species of the genus Allium. It is a bulb-forming plant with a characteristic pungent taste and aroma. The bulb, which is the most commonly consumed part, is a modified underground stem that serves as a food storage organ. Onions are cultivated and used around the world as a vegetable and a condiment. The plant produces a small, white flower in the summer. The word "onion" comes from the Latin word unio, referring to the plant's single bulb. In Hebrew, the onion is called bazal (בצל). Other relevant translations include cebolla in Spanish, oignon in French, Zwiebel in German, and cipolla in Italian. Onions are a fundamental ingredient in many cuisines, providing a sharp, pungent flavor that forms the basis of many dishes. They are also rich in vitamins, minerals, and antioxidants, contributing to their widespread use in both cooking and traditional medicine.
