I wish someone would explain how to use ?

Sure! The question mark symbol "?" is primarily used in written language to indicate a question or request for information. Here are a few common ways to use it:

1. Direct questions: When asking a direct question, place the question mark at the end of the sentence. For example: "What is your name?"

2. Indirect questions: When reporting a question indirectly, the question mark is not necessary. For example: She asked me what my name was.

3. Tag questions: These are short questions added at the end of a statement to seek confirmation or agreement. For example: "You like ice cream, don't you?"

4. Rhetorical questions: These are questions asked for effect or to make a point, not requiring an answer. For example: "Who doesn't love a good cup of coffee?"

5. Multiple-choice questions: In written tests or surveys, the question mark is often used to indicate that the sentence is a question and the reader should choose one of the provided options.

6. In informal writing: The question mark can be used to convey a sense of uncertainty, confusion, or surprise. For example: "You did what?"

Remember, the question mark is an important punctuation mark that helps clarify the intention behind a sentence.
