It belongs to the Solanaceae family, which is the nightshade family. While it is often treated as a vegetable in cooking, it is botanically classified as a berry. This classification means the fruit contains many small, soft, edible seeds. The eggplant is highly valued in culinary arts because of its unique texture. Its flesh is spongy and absorbent, allowing it to soak up oils and various flavors during the cooking process.

The eggplant plant is a delicate, tropical perennial. In temperate climates, people often grow it as a tender or half-hardy annual. The physical structure of the plant can be quite striking. It grows tall and features large, broad leaves with coarse lobes. The stems are frequently covered in sharp spines. The flowers of the plant range from white to purple in color. These flowers have a five-lobed corolla and bright yellow stamens. Some semiwild varieties can reach impressive sizes, with leaves that are very long and broad.

There is great variety among eggplant cultivars. Many common varieties produce glossy, purple fruit with white flesh. These fruits are often shaped like an egg, which is where one name for the plant originates. Other cultivars produce white fruit that is longer in shape. Wild eggplant fruits are much smaller, measuring less than 1 cm in diameter. A notable chemical characteristic of the seeds is their bitter taste. This bitterness comes from nicotinoid alkaloids, which are substances also found in tobacco. Additionally, the flesh of the fruit turns brown rapidly when it touches oxygen in the air.

The history of the eggplant involves complex patterns of domestication and migration. Scientists believe the plant may have undergone two independent domestications. One likely occurred in South Asia and another in East Asia. The plant was originally domesticated from wild nightshade species like *S. incanum*. It has been cultivated in southern and eastern Asia since prehistory. The earliest written mention appears in a Chinese text from 59 BCE. Later, the plant was described in the *Qimin Yaoshu*, an agricultural treatise from 544 CE.

The eggplant traveled to Europe through the Iberian Peninsula. It became a staple among Muslim and Jewish communities in the Mediterranean. Because of the many Arabic and North African names for the vegetable, historians suggest it was cultivated in the Mediterranean by Arabs during the early Middle Ages. The plant arrived in Spain during the 8th century. By the 12th century, the book *The Book of Agriculture* by Ibn Al-Awwam described how to grow aubergines in Muslim Spain. It remained relatively obscure in other parts of Europe until the 17th century.

The eggplant has a profusion of different names depending on the region. In North America and Australia, the term "eggplant" is most common. This name was first recorded in 1763 and originally referred to white varieties that look like hen's eggs. In British, Irish, and New Zealand English, it is called an "aubergine." In South Asia and South Africa, it is known as "brinjal." Many of these names derive from the Arabic word *bāḏinjān*. This word itself came from ancient Dravidian languages. The Sanskrit word *vātin-gaṇa* even meant a class that removes "wind-disorder" because it was thought to cure flatulence.

The eggplant is closely related to several other important crops. It is part of the same genus, *Solanum*, as the tomato, chili pepper, and potato. However, while those relatives originated in the Americas, the eggplant is native to the Eurasia region. The plant's relationship to other nightshades caused some historical misconceptions. Because of this connection, people once believed the fruit was extremely poisonous. In 13th-century Italian folklore, it was even thought to cause insanity. This led to names like "mad-apple" or "raging apple." Today, the plant is a massive global crop. In 2023, world production was significant, with China and India producing 85% of the total amount.
