What is the primary use of parentheses in writing?

The primary use of parentheses in writing is to interrupt the main sentence with extra information. Parentheses are typically used to provide additional context, clarifications, or elaborations that are not essential to the main point being made. This allows writers to include supplementary details without disrupting the flow of the primary message. The information within the parentheses can enhance understanding or provide examples, but the sentence would still make sense if the parentheses were removed.

By using parentheses, the writer can convey additional thoughts or information while maintaining the sentence's coherence. It is important to note that the material inside parentheses is often considered less critical than the main sentence, meaning that readers can choose to skip over it without losing the essential message.
