Here's what it generally encompasses:
* Pronunciation: SAE emphasizes a relatively neutral accent, often based on the speech patterns of the Mid-Atlantic region (think news anchors and broadcasters).
* Grammar: SAE follows the rules of traditional English grammar, with less tolerance for regional variations or slang.
* Vocabulary: It uses common, widely understood words, avoiding slang or regionalisms unless they are particularly well-known.
* Spelling: SAE follows the standard spelling conventions established by dictionaries and style guides (e.g., Webster's Dictionary, The Chicago Manual of Style).
Important Points:
* No "official" version: There is no official governing body that dictates SAE.
* Regional variations: Even within SAE, regional differences in pronunciation and vocabulary are common.
* Not inherently superior: SAE is considered a prestigious form of English, but it's not inherently better or more correct than other varieties.
* Context is key: The appropriate use of language depends on the context. While SAE might be preferred in formal settings, other varieties are perfectly acceptable in casual settings.
In essence, SAE serves as a common ground for communication, ensuring that most Americans can understand each other, especially in formal settings. It's a useful concept to be aware of, but it's important to remember that language is constantly evolving, and no single version is inherently "right" or "wrong."
