Are these 3 sentences that use commas in different ways and why they are needed? I need to go to the supermarket to get cheese, cereal, and fruit. The commas are there to show the items are sperate. My brother went to the park, but I stayed home. The commas are there to make a compound sentence. After eating my lunch, I decided to go for a walk. The comma is used to separate two independent clauses.

Answer 1

Yes, you are correct!

In the sentence "I need to go to the supermarket to get cheese, cereal, and fruit," the commas are used to separate the items in a list, indicating that "cheese," "cereal," and "fruit" are three separate things to be obtained.

In "My brother went to the park, but I stayed home," the comma is used to separate two independent clauses that are joined by a coordinating conjunction ("but"). The comma helps to create a compound sentence.

Lastly, in "After eating my lunch, I decided to go for a walk," the comma is used to separate the dependent clause ("After eating my lunch") from the independent clause ("I decided to go for a walk"). The comma helps to indicate the pause between these two parts of the sentence.
