Articles in the Simple English Wikipedia use fewer words and easier grammar than the ordinary English Wikipedia. The Simple English Wikipedia is also for people with different needs, such as students, children, adults with learning difficulties, and people who are trying to learn English. Other people may use the Simple English Wikipedia because simple language helps them to understand unfamiliar topics or complex ideas. Source
The Simple English Wikipedia has been created by, in effect “translating” normal English Wikipedia pages into simpler language. There aren’t Simple English versions of every page, but with over 100,000 articles it still has articles on a wide range of topics.
Why not give it a try?
