Summarizing a text in your own words

A useful summary states the source's main points accurately and briefly, in your own sentences. It is not a shorter copy of the text, and it should not add opinions or conclusions the author did not reach. Most of the work happens before you write. You need to decide which points matter, what the author is trying to do and how the points relate to each other.

Summary assignments are usually set to show that a reader has understood a text, not only that they can locate its phrases. Writing in your own words is therefore a skill with a clear test: could you explain the text to someone who has not read it, without relying on its exact sentences? If the answer is yes, the summary is doing its job.

Identify the main points first

Read the whole text once to understand its purpose and structure. Then, on a second pass, mark the central claim, the main supporting points and the conclusion. While marking the main points, set aside examples, anecdotes and figures unless the text depends on them. Write one sentence that states the text's purpose, then list no more than three to five points beneath it. If you cannot state the purpose in one sentence, reread the introduction and the first paragraph of each section. The purpose, such as persuading readers, reporting findings or explaining a process, also decides which points belong. A summary of an argument must include the claim and its support, while a summary of a report may focus on the results and the methods.

Build the opening sentence of the summary from three parts: the author, the title and the purpose. A reader who has never seen the text should learn whose work it is, what it is called and what it sets out to do before any of its claims appear. Whether the text is a persuasive essay, a report of findings or a set of instructions, that one sentence sets the frame for everything that follows.

Paraphrase without copying the structure

• Close the text and write each main point from memory before you check the original.
• Replace the author's wording with your own, but keep technical terms that have no simpler equivalent.
• Compare your sentences with the original and rewrite any that follow its phrasing too closely.

Writing from memory is a useful test because it shows what you actually understood. Paraphrasing well means more than swapping in synonyms. Changing a few words while keeping the author's sentence structure still counts as copying in most school settings. Quote directly only when the exact wording matters, and mark those words with quotation marks and a citation. The most common problem is patchwriting, where a sentence keeps the source's order and rhythm while changing only a few words.

When the text defines a term, make sure your definition matches the author's meaning rather than the everyday use of the word. A word such as "significant" can have a precise statistical meaning in a research report, where it signals that a result is unlikely to be due to chance alone, and it can simply mean important in everyday speech. If the source uses a term in a specific sense, that sense should appear in your summary.

Attribute each idea to its source as you write. Reporting verbs such as "argues," "describes" and "concludes" show whose claim the summary records and keep your own view separate from the author's. Use "argues" for a claim, "describes" for a process or a set of events, and "concludes" for the author's final judgment. Using them consistently keeps the summary accurate about what the text asserts and what it only reports.

Check the summary against the source

After drafting, check the summary against the text for three things: accuracy, coverage and proportion. Accuracy means every claim in the summary appears in the source and says the same thing. Coverage means each main point is present. Proportion means the summary gives the most space to the points the author develops most fully. A common mistake is adding an opinion the author did not express, and another is dropping the qualifier that limits a claim, such as "in some cases" or "under these conditions."

A quick self-test helps. Put the source away, list the main points from memory and compare that list with your summary. Then reopen the text to verify any point you were unsure about. Where your memory and the summary disagree, the source decides, and the summary needs correction.

Length should match the assignment. If the instructions set a word count or a number of sentences, follow it exactly. Without instructions, a summary is usually a small fraction of the original, and a single paragraph is often enough for a short article. Add a citation that identifies the source if your teacher requires one, and keep quotation marks around any exact words you borrowed.

Do not pad the summary with minor details to make it look thorough. A summary that includes every example loses the main message, and it can read as a copy of the text rather than an understanding of it. Cut anything that a reader could skip without losing the central argument. The order of the summary matters too. A summary of a historical account usually follows the sequence of events, while a summary of an argument often groups points by theme.

A summary that passes these checks shows that you understood the text well enough to explain it without its exact words. That is the skill most summary assignments are designed to build, and it carries over to research, note-taking and reading for exams.
