Commas in a Series

A comma in a series is used to separate three or more items in a list to clarify the meaning of the sentence.

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

I bought apples, oranges, and bananas.

The purpose is to make the sentence clearer and easier to read by indicating the separation of items.

The correct sentence is 'I like to read, write, and draw.'

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

The correct sentence is 'We need eggs, milk, and bread.'

No change needed: 'I want to swim and play.' (only two items).

Commas help by indicating pauses and separating ideas, making the sentence easier to follow.

A common mistake is forgetting to add a comma before 'and' when listing three or more items.
