Prestige language means using fancy words and speaking in a certain way to make yourself seem important and smart to others. It's like wearing a very expensive suit to a party to impress people. Usually, this type of language is associated with people in authority, like teachers or rich people.
For example, instead of saying "I'm gonna go to the store," someone using prestige language might say "I shall proceed to the market." It may seem confusing or difficult to understand, but some people believe that using fancy language makes them sound more educated or sophisticated.
However, it's important to remember that not everyone speaks this way, and it's not necessary to use fancy words to communicate effectively. We should strive to communicate in a clear and concise way that everyone can understand, regardless of their background or education level.
