Why Punctuation Matters

Punctuation is the unsung hero of clear writing. A misplaced comma can change the entire meaning of a sentence. "Let's eat, grandma" versus "Let's eat grandma" — punctuation literally saves lives!

Common Punctuation Mistakes

• Missing commas — After introductory phrases, in lists, before conjunctions
• Apostrophe errors — Using "it's" instead of "its," or vice versa
• Run-on sentences — Missing periods or semicolons between independent clauses
• Quotation marks — Incorrect placement of periods and commas with quotes
