While the Midwest is known for having its own distinct dialect of English, often called Midwestern American English, it is not a specific form of speech in the same way that "slang" or "formal" are.
Midwestern American English is characterized by:
* The Northern Cities Vowel Shift: A series of vowel changes that affect words like "bad," "bag," and "cot."
* Merging of some vowel sounds: For example, the "cot" and "caught" vowels are often pronounced the same.
* Specific pronunciations: Some words, like "creek" or "route," are pronounced differently than in other regions.
* A more relaxed, less formal tone: This is often seen as a friendly and approachable style of communication.
So, while the Midwest is associated with a particular dialect, "Midwest" itself is not a form of speech.
