The Swazi are an Nguni-speaking people in southeastern Africa, chiefly in Swaziland and South Africa and some in Mozambique. Besides their language, Siswati, they speak Afrikaans in South Africa, English in South Africa and Swaziland, and Portuguese in Mozambique and South Africa as second languages. More Swazi live in South Africa than in Swaziland.
