Did you know that the basic English was invented in 1940? This simplified version of the language contains 850 words and is enough for basic communication. It was based on Charles Kay Ogden’s work. The teaching of English was made easier. Many books and documents were translated into this subset of the language.
The words in VocaBattle’s basic levels were selected with a similar goal: helping you to memorize a minimal amount of words that will allow you to communicate in a foreign language.
