Sahara desert

n. desert in northern Africa (the largest in the world)

The Sahara (, aṣ-ṣaḥrā´ al-koubra, "The Great Desert", ) is technically the world's second largest desert after Antarctica. At over 9,000,000 square kilometres (3,500,000 sq mi), it covers most parts of northern Africa; an area stretching from the Red Sea, including parts of the Mediterranean coasts, to the outskirts of the Atlantic ocean. It is almost as large as the United States, and is larger than Australia. As its name derives from an Arabic word meaning "desert": "ṣaḥrā´" (صحراء), to refer to the Sahara as the "Sahara Desert" can be considered a tautology.
