How to Use Commas in Dialogue

Khan Academy

This video provides a clear and engaging explanation of how to properly use commas when writing dialogue. Using a helpful "runway" metaphor, the narrators demonstrate the mechanics of punctuating speech in two common scenarios: when the speaker tag comes before the quote, and when the speaker tag follows the quote. The video uses specific sentence examples involving characters Guillermo and Roxane to visually illustrate where commas, periods, and quotation marks belong. The content focuses on the specific grammatical rules of "reported speech" or dialogue tags. Key themes include the function of commas as separators between narration and speech, the correct placement of punctuation inside or outside quotation marks, and the exceptions for question marks and exclamation points. The visual metaphor of an airplane taking off and landing helps solidify the concept of ramping up to or winding down from spoken words. For educators, this video serves as an excellent tool for teaching writing mechanics and editing skills. It simplifies a rule that often confuses students—specifically the counter-intuitive requirement to use a comma instead of a period at the end of a spoken sentence when a dialogue tag follows. Teachers can use this resource to introduce dialogue punctuation in creative writing units, support students during the editing phase of the writing process, or as a remediation tool for students struggling with writing mechanics.
