Guinea (/ˈɡɪni/ (About this soundlisten)), officially the Republic of Guinea (French: République de Guinée), is a west-coastal country in West Africa. Formerly known as French Guinea (French: Guinée française), the modern country is sometimes referred to as Guinea-Conakry in order to distinguish it from other countries with "Guinea" in the name and the eponymous region, such as Guinea-Bissau and Equatorial Guinea. Guinea has a population of 12.4 million and an area of 245,860 square kilometres (94,927 sq mi).
The sovereign state of Guinea is a republic with a president that is directly elected by the people and is head of state and head of government. The unicameral Guinean National Assembly is the legislative body of the country, and its members are also directly elected by the people. The judicial branch is led by the Guinea Supreme Court, the highest and final court of appeal in the country. The country is named after the Guinea region. Guinea is a traditional name for the region of Africa that lies along the Gulf of Guinea. It stretches north through the forested tropical regions and ends at the Sahel. The English term Guinea comes directly from the Portuguese word Guiné, which emerged in the mid-15th century to refer to the lands inhabited by the Guineus, a generic term for the black African peoples below the Senegal River, as opposed to the 'tawny' Zenaga Berbers, above it, whom they called Azenegues or Moors.
Guinea is a predominantly Islamic country, with Muslims representing 85 percent of the population. Guinea's people belong to twenty-four ethnic groups. French, the official language of Guinea, is the main language of communication in schools, in government administration, and the media, but more than twenty-four indigenous languages are also spoken.
