Ogden, in his book Basic for Science, gave an account of what is the sense of the word "Basic": "getting down to the roots of the purpose and structure of language, and specially designed as an instrument for the distribution of knowledge" (27).
The point here is that something basic is not necessarily simple. The word "basic" is, in fact, not on Ogden's list; it is not one of the 850. Some learners may have a hard time learning the basic part of the language. Sometimes it is necessary to have a completely new way to see things. Working hard on this part gives you the power to go on to higher levels.

Notes are generally on English or other languages, American or other writers or writings, and music or motion pictures based on those writings.
