用英语的缩写形式怎么说

In Engpsh, the abbreviation of a word or phrase is a shortened form of the original term. This can be done by using the first letter of each word in the phrase, or by using a combination of letters that represent the original term. For example, the abbreviation for "United States" is "U.S.", and the abbreviation for "electronic mail" is "email". Abbreviations are often used in written communication to save space and make text easier to read, but they should be used with caution in formal writing, as they may not be understood by all readers.
