| It is impossible that the people of the
world today could agree upon a single international language that everyone would
be able to speak and understand. In the United Nations there are five official
languages—English, Chinese, Russian, French and Spanish. How about making
one of them into an international language English has been worked on for this
purpose. A basic word list of 850 English words named Basic English was made.
These are the only verbs in the entire list: "come, go, give, keep, let, do,
put, make, say, be, seem, may, will, have, send. "Writing in Basic English may
require you to use a great number of words—as in having to say "it came to my
ear" instead of "I heard"—t you can still say anything you want to with just 850
