Commas In A Series

A comma in a series is used to separate three or more items in a list, making it clear that each item is distinct.

You should use a comma before 'and' in a list of three or more items, known as the Oxford comma, to clarify the separation of the last two items.

I bought apples, oranges, and bananas.

The purpose is to improve readability and avoid confusion by clearly separating items.

Add commas: I like to swim, run, and bike.

Add commas: 'My favorite colors are red, blue, and green.'

True, commas are not needed when listing only two items.

I have a dog, a cat, and a rabbit.

A common mistake is placing a comma after 'and' or before the last item incorrectly.

For breakfast, I had eggs, toast, and juice.
