Here's why:
* Standard English is a specific variety of English. It's the form used in formal writing, education, and official contexts. It's often based on a particular region or social group, but it's agreed upon as the "standard" form.
* Dialects are regional or social variations of a language. They have their own unique features, including vocabulary, grammar, pronunciation, and intonation. These differences can be significant, making them easily distinguishable from standard English.
Think of it this way:
* Standard English is like the official language of a country. It's the language used in government, education, and media.
* Dialects are like regional accents or slang. They are variations within the language, but they don't have official status.
It's important to remember:
* All dialects are equally valid and important. They are simply different ways of speaking the same language.
* No dialect is inherently "better" than another. They all have their own unique beauty and history.
So, while dialects are fascinating and important parts of language, they are not considered standard English.
