Commas in a Series

A comma in a series is used to separate three or more items in a list.

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

I bought apples, oranges, and bananas.

Commas in a series help clarify the items in a list, making the sentence easier to read.

I like to swim, bike, and run.

Not using commas can lead to confusion about the items in the list.

The correct sentence is: 'For breakfast, I had eggs, toast, and juice.'

Use commas to separate items in a list of three or more.

It is not necessary, but it is recommended for clarity.

We need to buy milk, eggs, bread, and cheese.
