Using Commas for Direct Address (the Vocative Case)
The Quick AnswerWhen addressing a person or thing directly, the name used must be offset with a comma (or commas if it's mid-sentence). For example:
- Jackie, are you leaving so soon? (As Jackie is being addressed directly, her name is offset with a comma.)
- I know your sister, Michael. (As Michael is being addressed directly, his name is offset with a comma.)
