For example," His voice resonates like a lion's roar." 3. Irony: To convey a sense of humor by expressing the opposite meaning. For example," This city is small but everyone is confident and crowded like ants." 4. Pun: The use of a word or phrase with a pun to achieve a humorous effect. For example,"Why do doctors like to wear black clothes because they want to misdiagnose?" To develop a sense of humor, one needed to have a rich knowledge of language and a sense of humor.
