Good writing requires correct grammar. While many readers might not consciously notice punctuation errors, mastery of punctuation is required for effective writing. Perhaps no punctuation mark is as misused as the comma. Commas, however, serve an important purpose. They ensure the reader can more easily comprehend the written work with clarity and well-placed pauses.
Avoid grammar errors in your academic or business writing. Ensure you create the correct impressions for your teachers, professors, co-workers, boss, and peers with a correct use of commas.
