Commas in a Series

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

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.

The sentence should be: 'I like to read, swim, and play.'

The correct way is: 'dogs, cats, and birds'.

False. It depends on whether you are using the Oxford comma.

Add commas: 'I have apples, oranges, and grapes.'

'I like to swim and run.' (Only two items, no comma needed.)

Use commas to separate adjectives that equally describe a noun, e.g., 'It was a long, tiring journey.'
