An exclamation point is a punctuation mark used to indicate strong feelings or high volume, such as excitement, surprise, or anger. It is represented by a vertical line with a dot below it (!). In writing, it helps convey the tone of a sentence, making it clear that the statement is meant to be emphatic. Exclamation points are commonly found in various forms of communication, including text messages, social media posts, and literature. While they can enhance the emotional impact of a sentence, overusing them can diminish their effectiveness and make writing seem less formal.
