Ogden's List of 850 Basic Words
The 850 words of Basic English are made of three different groups: 100 words for operations and so on, and 600 words for things, and 150 words for qualities.
The 100 for operations, directions and other important works of making other words joined together are the truly necessary ones.
The 600 for things are the NAMES of things, living or not living. Words like "look," "talk," and "walk" are the names of acts, but they are here because they are used, in Basic English and frequently in regular English, like things. You may say, for example, "take a look," "give a talk," or "have a walk."
Those 600 are made of two different groups: 400 general words and 200 pictured words.
The 150 for qualities are the words for "how." They are made of two different groups: 100 general ones and 50 opposites.
