Simple English Wikipedia

The Simple English Wikipedia is an English-language edition of the Wikipedia online encyclopedia written primarily in Basic English and Learning English. It was launched in 2001. It is one of eight Wikipedias written in an Anglic language or English-based pidgin/creole, the others being English, Scots, Old English, Pitkern-Norfuk, Tok Pisin, Jamaican Patois, and Sranan Tongo. The site has the stated aim of providing an encyclopedia for "people with different needs, such as students, children, adults with learning difficulties, and people who are trying to learn English". As of , the site contains over content pages, and has more than registered users, of whom are currently active.
Simple English Wikipedia's basic presentation style makes it very helpful for beginners learning English. Its simpler word structure and syntax, while detracting from the raw information standpoint, can make the information easy to understand. 
Material from the Simple English Wikipedia formed the basis for One Encyclopedia per Child, a project in One Laptop per Child that ended in 2014. 
Website structure.
The articles on the Simple English Wikipedia are usually shorter than their English Wikipedia counterparts, typically presenting only basic information. Tim Dowling of "The Guardian" newspaper explained that "the Simple English version tends to stick to commonly accepted facts". The interface is also more simply labeled; for instance, the "Random article" link on the English Wikipedia is replaced with a "Show any page" link; users are invited to "change" rather than "edit" pages; clicking on a shows a "page not created" message rather than the usual "page does not exist". The project encourages, but does not enforce, use of a vocabulary of around 1,500 common English words that is based on Basic English, an 850-word controlled natural language created by Charles Kay Ogden in the 1920s.
