A style manual is a guide that provides rules and standards for writing and formatting documents. It helps ensure consistency in language, punctuation, and citation practices across various types of writing. Common examples of style manuals include the APA (American Psychological Association) and MLA (Modern Language Association) guides, which are often used in academic settings. These manuals are essential for writers, editors, and researchers, as they clarify how to present information clearly and professionally. By following a style manual, individuals can improve the readability of their work and maintain a uniform appearance in publications, reports, and essays.
