Zulu is one of the official languages of South Africa and is a member of the Bantu/Nguni family of languages. It is spoken by about 9 million people mainly in Zululand and northern Natal in South Africa and also in Botswana, Lesotho, Malawi, Mozambique and Swaziland.
During the early 19th century Christian missionaries, including J W Colenso, S B Stone, H Callaway and Lewis Grant devised a way to write Zulu. The first Zulu Christian booklet Incwadi Yokuqala Yabafundayo was written by Newton Adams, George Newton and Aldin Grout between 1837-8 and explained the spelling of Zulu words and the history of the Old Testament. The first Zulu version of the bible was produced between 1845-1883 and in 1859 L. Grout published the first Zulu grammar book.
