Concept sheet | English Language Arts

Comma Uses

Rules

Commas are used:

  • to separate clauses and phrases

  • to separate elements in a list

  • to address by name

  • for tag questions

  • for an interjection.

 The first word following a comma is not capitalized.
 

Example

To separate clauses or elements in a list

Selina the inventor feeding her cat who refuses the food.

To address by name, for tag questions and interjections

Selina the inventor trying and failing to get her cat to eat the food she put out.
Important!

Comma placement can affect the meaning of a sentence.

With a comma: address by name

Selina the inventor telling her cat she’s hungry and it’s time to eat.

Without a comma: name becomes verb object

Selina the inventor telling her cat she’s hungry and that she’s going to eat him.
