📚 Quick Study Guide

    📌 A nonessential clause adds extra information to a sentence but isn't crucial to its core meaning. The sentence still makes sense without it. ✏️ Nonessential clauses are always set off by commas (or dashes or parentheses, but mostly commas!). 📝 If the nonessential clause is in the middle of the sentence, it needs a comma before and after. 📍 If it's at the end, it needs a comma before it. 💡 Think of it like a little parenthetical remark within your sentence.
