Final answer:
Commas should be placed around nonessential information such as in 'Mrs. Morin, my teacher, loves reading,' where 'my teacher' is an appositive. Proper comma placement enhances clarity and meaning. Correctly punctuated examples demonstrate the right usage of commas in various contexts.
Step-by-step explanation:
In the sentence “Mrs. Morin, my teacher, loves reading,” commas are used to set apart the appositive ‘my teacher’ because it is a nonessential clause providing additional information about Mrs. Morin. If the appositive is removed, the sentence still makes sense:
“Mrs. Morin loves reading.” This demonstrates the proper use of commas around nonessential information. Understanding where to place commas can ensure the clarity of your writing and helps convey the intended meaning to the reader.
