Summarizing is defined as taking a lot of information and creating a condensed version that covers the main points. An example of summarizing is writing a three or four-sentence description that touches upon the main points of a long book. To express the most important facts or ideas about something or someone in a paragraph manner. A summary is a shortened version of a text that highlights its key points.An overview of content that provides a reader with the overarching theme, but does not expand on specific details. A summary describes a larger work (such as an entire book, speech, or research project), and should include noticeably less content then the original work. Summaries can save a reader time because it prevents the reader from having to actually go through and filter the important information from the unimportant.
