     The Gullah people in the southern US have honored their culture for more than 100 years. Living

mainly on the Sea Islands and coastal areas of South Carolina, Georgia and Floride, the Gullah people,

an African-American group, have a rich culture including their own language. It is a Creole language

created by slaves who came to the US from the West Africa in the 1800s. It combines West African

languages with English.

     For many years efforts have been made to save the Gullah language. One project began in 1979.

Its goal was to translate the New Testament part of the Bible into Gullah. Experts say that it was a

difficult process because Gullah is not a written language. It is a spoken language only.

     A team of Gullah speakers began working on the translation to make the Bible easier to understand

for those who spoke Gullah as their main language. The Gullah version is called De Nyew Testament.

It is written in English on one side of the page, and next to it, there is a Gullah translation. De Nyew

Testament was published by the American Bible Society. The project also received help from the

Summer Institute of Linguistics, Wycliffe Bible Translators, the United Bible Societies and the Penn

Centre 

     Experts believe that the translated Bible is a major step towards saving the Gullah language and

traditions. "This is more than a Bible translation," says Robert Hodgson, at the American Bible Society.

"De Nyew Testament raises the Gullah language and culture to a new level." Ardell Greene is a member

of the translation team. She calls the book "a treasure". She says that the Gullah version of the Bible will

be read in churches and will help young people keep the Gullah language alive.
