Step-by-step explanation:
Dialects are unique forms of a common language that are associated with different regions and groups. The type of person who speaks or signs a dialect is typically someone who is part of a specific community or ethnic group that has developed its own linguistic patterns.
For example, certain dialects in the United States, such as Appalachian English or African American Vernacular English, are spoken by people from specific geographic regions or ethnic backgrounds. These dialects often reflect the historical influences and experiences of the people who speak them.
It is important to note that dialects can vary within a specific language and may have distinct features in terms of grammar, vocabulary, and pronunciation.
