Understanding Commas

To replace a period

To indicate a pause

To end a sentence

To show excitement

After every word

Nowhere in the list

Only at the end of the list

Between each item in the list

To separate every digit

To mark every third digit from right to left

To replace decimal points

To indicate the end of a number

Nowhere in the sentence

At the end of the second sentence

Before the joining word

After the first sentence

Despite

And

Although

Because
