Basic English

Basic English is a simplified form of English intended for international communication. It is limited to 850 selected words. "If one were to take the 25,000 word Oxford Pocket English Dictionary and take away the redundancies of our rich language and eliminate the words that can be made by putting together simpler words, we find that 90% of the concepts in that dictionary can be achieved with 850 words," said Charles K Ogden in his "Basic English: A General Introduction with Rules and Grammar" (1930). The shortened list makes simpler the effort to learn spelling and pronunciation irregularities. The rules of usage are identical to full English so that the practitioner communicates in perfectly good, but simple, English.
