What , means
Separate list items and set off extra information. In English, put a comma after many introductory phrases and before “and” or “but” joining two complete sentences.
Commas around a description mark it as extra. Leave them out when the description tells you which person or thing is meant.
In formal English, follow your style guide’s list punctuation, but keep commas needed for clarity.
In formal English, a comma alone cannot join two complete sentences.
