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.
