Substantive editing (content editing or developmental editing) is a comprehensive and deep level of editing. It focuses on a written work’s overall structure, content, and clarity. This type of editing goes beyond correcting grammar and spelling; it examines the flow of ideas, organization, tone, and the effectiveness of the message.

Key aspects of substantive editing include:

• Content Development: Ensuring that ideas are fully developed and clearly expressed.
• Clarity and Consistency: Making suggestions to improve clarity, remove ambiguity, and ensure consistent terminology and style.
• Audience Engagement: Assessing whether the content resonates with the intended audience and meets their needs.
• Organization: Evaluating the arrangement of chapters, sections, or paragraphs for logical flow and coherence.
• Content-Checking and Accuracy: Verifying information and ensuring that the content is accurate and credible.

Overall, substantive editing aims to enhance the effectiveness and quality of a manuscript.
