When is it appropriate to use an em dash in a sentence?

Using an em dash in a sentence is particularly effective for adding emphasis or clarification. The em dash serves as a versatile punctuation mark that can create a strong break in thought, allowing the writer to highlight important information or provide additional context. For instance, a writer might use an em dash to set off a remark or an explanation that is closely related to the preceding clause but adds extra detail or nuance. This creates a dramatic pause that draws the reader's attention to that specific part of the sentence.

When a writer chooses to use an em dash for emphasis, it can enhance the reader's understanding by signaling that the information following the em dash is significant. This makes it an excellent tool for enhancing clarity and ensuring that the reader focuses on specific ideas or points the writer wishes to emphasize.
