📚 Quick Study Guide: Punctuating Introductory Elements
- 👉 Use a comma after an introductory dependent clause. These clauses typically begin with subordinating conjunctions like after, although, as, because, before, if, since, unless, when, while.
- ✍️ Use a comma after an introductory phrase of four or more words. This includes prepositional phrases (e.g., In the beginning of the story), participial phrases (e.g., Running quickly down the street), and infinitive phrases (e.g., To understand the concept fully).
- 🧐 Use a comma after an introductory adverb or adverbial phrase that modifies the entire sentence, especially if it's long or creates a pause. Short adverbs like However, Therefore, Meanwhile almost always take a comma.
- 🛑 Generally, do NOT use a comma after a short introductory prepositional phrase (three words or fewer) if it flows smoothly into the sentence, unless it causes confusion or a distinct pause is intended for emphasis.
- ❌ Do NOT use a comma after an introductory element if it's the subject of the sentence or directly followed by the main verb. E.g., That she was late was obvious.
- 💬 Use a comma after an introductory interjection (e.g., Well, Oh, Yes) or a direct address (e.g., John, please come here).
