The comma placement rule for introductory elements is straightforward: place a comma immediately after the introductory element and before the main clause begins. This comma acts as a pause that helps readers identify where the introduction ends and the main idea starts.
For example, in the sentence "Before breakfast, the family went for a walk," the comma comes after "breakfast" because that completes the introductory phrase. Understanding commas with coordinating conjunctions helps students master various comma applications in writing.
Types of Introductory Elements
Time phrases tell when something happened, such as "Yesterday afternoon" or "During recess." Location phrases indicate where events occur, like "In the garden" or "At the library." Introductory words include responses like "Yes" and "No" that begin sentences.
Each type follows the same comma rule: the introductory element is followed by a comma before the main sentence continues. This consistent pattern makes comma placement with introductory elements predictable and easy to learn.
