In writing, what does "synthesis" mean?

Synthesis in writing refers to the process of combining information, ideas, or insights from multiple sources to create a comprehensive understanding of a topic. When synthesizing, a writer pulls together varied perspectives, research findings, and arguments to form a cohesive narrative or argument. This enhances the depth and richness of the analysis and allows for a more nuanced exploration of the subject, demonstrating how different pieces of information interconnect and contribute to a broader context.

In contrast, a summary of a single source merely restates its main points without integrating additional materials, while repetition of an argument focuses on restating what has already been expressed without introducing new ideas or insights. Isolating different ideas does not create a connected or overarching understanding, but rather keeps concepts separate, which undermines the purpose of synthesis.
