Rule 9 in English refers to the guideline for using commas with non-essential information. When additional information in a sentence is non-essential and can be removed without altering the core meaning, it should be surrounded by commas. For example, 'My brother, who lives in New York, is visiting us.' Removing the clause 'who lives in New York' doesn’t change the fundamental statement.**
