Why Spanish Uses EE. UU. as Abbreviation for U.S.

Why Spanish Uses EE. UU. as Abbreviation for U.S. Once you learn that Estados Unidos is Spanish for United States, you might predict that its abbreviation would be EU, just as we often use U.S. (or USA) in English. But the standard abbreviation is EE. UU. The Rule for Plural Abbreviations Although the abbreviation may seem unusual to Spanish students, abbreviations like it are common in standard written Spanish when shortening plural forms. Although the use of the periods in the abbreviation is standard usage and considered mandatory by some authorities, it isnt unusual to see the abbreviation without the periods: EEUU or EE UU. Sometimes the abbreviation EUA (for Estados Unidos de Amà ©rica) is used, and even USA can be found in trendy circles. Basically, the doubled letters (such abbreviations are called abreviaturas dobles in Spanish) are used to indicate that the main word abbreviated is plural. However, such a doubling of letters isnt if the plural word isnt the main noun in the phrase. For example, Organizacià ³n de las Naciones Unidas (United Nations) is ONU (U.N. in English.) The main noun here, the one that gives the phrase its gender, is singular: organizacià ³n. The doubling of letters comes from Latin, which explains some of the double-letter Latin abbreviations used in English also, such as pp. for pages and mss. for manuscripts. Identical abbreviations are used in Spanish: pp. for pginas and mss. for manuscritos. (Also commonly used is pgs. for pginas.) Such doubling is used typically when a single letter stands for a word. It isnt used used for most other abbreviations. For example, while ejemplo (example) can be abbreviated as ej., the plural form (that is, for examples) is ejs. Similarly, while usted (singular you) is abbreviated Ud., its plural form (plural you) is Uds. One of the exceptions is that the abbreviation for Buenos Aires (the city in Argentina) is Bs. As. Other Doubled Abbreviations Here are some of the other Spanish abbreviations that double the letters in the same way as EE. UU.: AA. PP. for Administracià ³n Pà ºblica (public administration)aa. vv. or AA. VV. for autores varios (various authors); VV. AA. and vv. aa. are also usedAA.
