Interjections
* Yes, an introductory comma is usually used after an interjection. Interjections are words or phrases that express strong emotion (e.g., "Wow!", "Oh no!", "Goodness!").
Example:
* Wow, that was an amazing performance!
Participial Phrases
* Yes, an introductory comma is often used after a participial phrase. A participial phrase is a group of words that functions as an adjective and starts with a present or past participle (e.g., "running," "eaten").
Example:
* Running through the park, I saw a squirrel.
Important Notes:
* Sometimes, a comma isn't needed after a short, introductory participial phrase if it's closely connected to the main clause. For example: "Smiling broadly, she accepted the award."
* The placement of the comma depends on the specific context and whether the phrase is introductory or not.
Here's a simple way to check:
1. If the phrase comes at the beginning of the sentence and describes the subject: Use a comma.
2. If the phrase modifies a noun within the sentence: You likely won't need a comma.
Examples:
* Introductory participial phrase with a comma: Walking through the forest, I stumbled upon a hidden waterfall.
* Participial phrase within the sentence without a comma: The dog, wagging its tail, greeted its owner.
