Usage
What does acronym mean? An acronym is a word formed by abbreviating a phrase by combining certain letters of words in the phrase (often the first initial of each) into a single term.Common examples of acronyms include NASA (an acronym for National Aeronautics and Space Administration) and FOMO (a slang acronym for fear of missing out). The word scuba comes from an acronym for self-contained underwater breathing apparatus.Although acronym is sometimes used generally to refer to any term formed from this kind of abbreviation, it typically refers to ones that can be pronounced as a word. This is sometimes contrasted with an initialism.What’s the difference between an acronym and an initialism?Initialism is sometimes used as a synonym for acronym, but most technically it refers to an abbreviation in which each initial is pronounced separately (instead of pronouncing them together as a single word, as in scuba or NASA). For example, FBI is an initialism of Federal Bureau of Investigation; TMI is an initialism of too much information.Acronyms are often associated with their use in certain fields that use a lot of technical terms, like science, tech, and the military. But they’re popular in all kinds of contexts since they’re an easy way to make long phrases much shorter.Example: STEM is an acronym that stands for “Science, Technology, Engineering, and Mathematics.”
