I believe in basic English

A person can overcome his fear of public speaking by using language with which he is comfortable, so that both he and his audience are relaxed He should not (1) ape pedantic speakers or those who indulge in gobbledygook, (2) be ambiguous, (3) use redundancies, (4) monounce words, (5) confuse word meanings, or (6) ignore changes in the English language. To choose exactly the right words to express his thoughts, a speaker needs a large vocabulary. The only way to acquire such a vocabulary is to read-widely, listen carefully, and practice assiduously each new word one encounters.
