To condense information:
* For brevity: Summarizing allows the writer to present a lot of information concisely, making it easier for the reader to grasp the key points.
* For clarity: A summary can simplify complex or dense material, making it more accessible to the reader.
* For focus: Summarizing helps the writer to highlight the most important information and avoid extraneous details.
To provide context:
* To introduce a topic: A summary can introduce a reader to a topic they may not be familiar with, setting the stage for further discussion.
* To connect ideas: A summary can connect different parts of a text, showing how they relate to each other.
* To review previous points: A summary can remind the reader of important points that have already been discussed.
To analyze and evaluate:
* To compare and contrast: Summaries can be used to compare and contrast different perspectives or theories.
* To critique: Summaries can be used to highlight the strengths and weaknesses of an argument or idea.
To persuade:
* To build an argument: Summaries can be used to build an argument by providing supporting evidence or highlighting key points.
* To counter opposing views: Summaries can be used to refute opposing views by highlighting their flaws or limitations.
Beyond these general reasons, specific contexts might call for summary:
* Academic writing: Summaries are common in academic writing to provide a concise overview of research findings, literature reviews, or theoretical frameworks.
* Journalism: Summaries are used to present news stories in a concise and engaging manner.
* Business writing: Summaries are used to present complex data, market analyses, or proposals in a clear and compelling way.
Ultimately, the reason a writer might use summary depends on their purpose and audience. But the goal is always to communicate information effectively and efficiently.
