The best way to make the most effective use of a comma is to follow the rules of grammar. A comma should be used when a sentence is broken up into two or more independent clauses, and it should also be used in lists and series. Additionally, commas can be used to separate items within a list, such as numbers, dates, and titles. When using commas correctly, your writing will flow smoothly and create an elegant effect.
