An acronym is a word formed by the initial letters of two or more words. For example, UN is an acronym for “United Nations.” Some people are even known by acronyms, such as JFK for former U.S. President John F. Kennedy, or CFO for a company’s Chief Financial Officer. We usually pronounce acronyms by saying each of their letters separately. Do you know these common acronyms in English?
