One way of improving one’s diction is through reading. I
believe that when you read, you get to learn a variety of words. When reading
books, make sure that you have a dictionary with you to help you understand
words that are not normally use in casual conversations. Aside from that, you
should also practice using those new words in speaking and writing to help you
gain confidence in speaking or writing the words.
