What are some common punctuation marks used to indicate additional information or explanations within a sentence?

Some common punctuation marks used to indicate additional information or explanations within a sentence are commas, parentheses, and dashes.

- Commas: You can use commas to set off nonessential information or clauses within a sentence. Nonessential information provides extra details but can be removed without changing the overall meaning of the sentence. For example, "The book, which was published last year, is now a bestseller."

- Parentheses: Parentheses are used to enclose additional information within a sentence that is not necessary for the main point. This information can be thought of as an aside. For example, "I love going to the movies (especially action films) with my friends."

- Dashes: Dashes can be used to indicate an abrupt change or interruption in thought within a sentence. They are often used to provide emphasis or add further clarification. For example, "She finally found her car keys—after searching for hours—in the pocket of her jacket."

Remember, the choice of punctuation depends on the specific context and the effect you want to achieve. It's always a good idea to proofread your writing and ensure that the punctuation marks you use accurately convey your intended meaning.
