I'd like to learn more about the different types of commas. Can you help me?

Sure, I can help! Commas are a punctuation mark that is used to separate clauses in a sentence. There are several types of commas, each with its own purpose and use. The most common type is the serial comma, which is used to separate items within a series or list. Other types include the Oxford comma, which is used to create clarity when listing two or more items that could be construed as a single unit, and the non-standard comma, which is used to indicate an abrupt change in thought.
