 | | Sometimes, periods are used for certain acronyms but not others; a notable instance in American English is to write United States, European Union, and United Nations as U.S., EU, and UN respectively. |
 | | Acronyms that were originally capitalized (with or without periods) but have since "stood the test of time" by entering the vocabulary as generic words are no longer abbreviated with capital letters nor with any periods—e.g., sonar, radar, lidar, laser, and scuba. |
 | | Acronyms are often referred to with only the first letter of the abbreviation capitalised. |
