Parentheses in Academic Writing: Rules and Examples

📚 Quick Study Guide

• 🔑 Parentheses are used to add extra information, explanations, or clarifications to a sentence.
• ✍️ Information within parentheses should be helpful but not essential to the sentence's main meaning.

• 📍 When only part of a sentence is enclosed, the punctuation goes outside. Example: The cat (a Persian) sat on the mat.
