What is a comma primarily used for in writing?

The primary function of a comma in writing is to indicate a pause. Commas are utilized to create natural breaks within sentences, which helps clarify meaning and improve the flow of the text. By placing a comma, a writer can signal to the reader that there is a slight interruption in the thought process, allowing for better comprehension of complex sentences or lists. This pause can also help in distinguishing between different elements in a sentence, thereby enhancing clarity.

For example, in a series of items, commas separate each element, helping the reader to easily distinguish between them. Additionally, when commas are used in longer, compound sentences, they can help separate clauses and ideas, making the writing less cumbersome and easier to follow. This use of pauses through commas is an essential aspect of effective writing, ensuring that the reader can understand the intended meaning without confusion.
