Summarizing and Paraphrasing
What Is This?
Summarizing means condensing a text into a much shorter version that captures only the most important ideas. A good summary is brief, accurate, and in your own words — it leaves out minor details, examples, and repetition.
Paraphrasing means restating a specific passage or section in your own words, keeping roughly the same length and level of detail. A paraphrase shows that you understood what you read and can express it differently, without simply copying the original.
These are two different skills with different purposes:
| Summary | Paraphrase | |
|---|---|---|
| Length | Much shorter than the original | Similar length to the original |
| Detail | Only key ideas | Most details, restated |
| Purpose | Condense and distil | Restate in own words |
| When used | After reading a whole passage | After reading a section or sentence |
Why Does It Matter?
Summarizing and paraphrasing are among the most essential skills in academic life and beyond. You need them to:
- Take notes from textbooks without copying word for word
- Write research reports using sources without plagiarism
- Explain what you have read to someone else
- Demonstrate reading comprehension
- Build arguments using evidence from texts
Both skills require genuine understanding. You cannot summarize or paraphrase well if you only half-understand what you read — which is exactly why these are such powerful learning tools.
How to Summarize
A strong summary:
- Identifies the main idea — what is this passage fundamentally about?
- Includes only key supporting points — which details are necessary to understand the main idea?
- Leaves out minor details, examples, and repetition — what can be cut without losing the essential meaning?
- Uses your own words — you are not copying; you are distilling
- Is significantly shorter — aim for roughly one quarter of the original length for a short passage
The Three-Step Summary Process
Step 1 — Read the whole passage. Do not try to summarize paragraph by paragraph on first read. Understand the whole.
Step 2 — Identify the main idea and the key points. Ask: what is the author's central message? What are the two or three most important supporting ideas?
Step 3 — Write the summary without looking at the original. Put the text aside, then write what you remember. This forces you to use your own words rather than copying phrases from the source.
Worked Example: Summary
Original passage (120 words): "The black-footed ferret was once thought to be extinct. After the last known wild colony was discovered in Wyoming in 1981, scientists launched an emergency captive breeding programme. The colony, however, was struck by canine distemper and sylvatic plague — two devastating diseases — and nearly all the animals died. By 1987, only 18 ferrets remained alive in captivity. Through careful breeding, disease management, and habitat restoration, the captive population slowly grew. Ferrets bred in captivity were gradually reintroduced to protected grassland habitats across the western United States and Canada. Today, several hundred wild black-footed ferrets exist, though the species remains among the most endangered mammals in North America."
Summary (45 words): The black-footed ferret nearly went extinct in the 1980s after disease devastated its last wild colony, leaving only 18 survivors. A captive breeding and reintroduction programme slowly rebuilt the population, and today several hundred live in the wild — though the species remains endangered.
Notice: the summary captures the beginning (near extinction), the crisis (disease, 18 survivors), the response (captive breeding and reintroduction), and the outcome (hundreds in the wild, still endangered). All minor details (Wyoming, 1981, specific disease names, specific countries) are omitted.
How to Paraphrase
A strong paraphrase:
- Reads and understands the original — before you can restate, you must understand
- Changes the vocabulary — use synonyms, different phrasing
- Changes the sentence structure — rearrange, combine, or split sentences
- Keeps the meaning — the idea must be preserved accurately
- Does not keep long phrases from the original — if more than four or five words in a row remain the same, you are copying, not paraphrasing
Worked Example: Paraphrase
Original sentence: "The black-footed ferret was once thought to be extinct, but the last known wild colony was discovered in Wyoming in 1981."
Poor paraphrase (too close to original): "The black-footed ferret was once considered extinct, but the last known wild colony was found in Wyoming in 1981." This only replaces two words ("thought to be" → "considered," "discovered" → "found") — it is still mostly copied.
Strong paraphrase: "Scientists believed the black-footed ferret had died out entirely, until a wild population was located in Wyoming in 1981." New vocabulary, restructured sentence, same meaning — this is a genuine paraphrase.
What Makes a POOR Summary or Paraphrase?
Poor summaries:
- Too long — includes minor details that should be cut
- Too short — misses key ideas and loses the meaning
- Copies from the original — uses the same sentences or phrases
- Adds information — includes things the original did not say
- Changes the meaning — distorts or misrepresents what the author said
Poor paraphrases:
- Swaps only a few words — keeps the original sentence structure and most of the vocabulary (this is patchwork copying, not paraphrasing)
- Changes the meaning — introduces inaccuracies when restating
- Loses important details — a paraphrase should keep the level of detail, unlike a summary
Quoting vs Paraphrasing
When you use information from a source, you have two choices:
Quote — copy the exact words and put them in quotation marks. Use quotes when the exact words matter (a definition, a famous phrase, or a specific claim).
Paraphrase — restate in your own words. Use paraphrases most of the time — they show you understand the material and integrate more naturally into your own writing.
You should not quote long passages when a paraphrase would do. Over-quoting suggests you are hiding behind the source rather than engaging with it.
Common Mistakes
Mistake 1: Confusing summary with paraphrase
A summary is much shorter and leaves out details. A paraphrase keeps the detail but uses different words. They are different tools for different situations.
Mistake 2: Near-copying in a paraphrase
Changing a few words while keeping the sentence structure and most vocabulary is not paraphrasing — it is patchwork copying. A genuine paraphrase reconstructs the idea from scratch in your own voice.
Mistake 3: Over-summarizing
Cutting so much that key information is lost is a failed summary. A summary must be shorter, but it must also be complete enough to stand alone.
Mistake 4: Changing the meaning
The most important rule: both summaries and paraphrases must be accurate. Never distort what the original said, even if you restate it very differently.
Key Takeaways
- Summarizing condenses a text to its main ideas — significantly shorter, in your own words
- Paraphrasing restates a passage in your own words — similar length, all details kept
- Summary: main idea + key points only; Paraphrase: all details, different expression
- Three-step summary process: read the whole → identify main idea and key points → write without looking at the original
- A paraphrase must change both vocabulary AND sentence structure
- Neither a summary nor a paraphrase should copy long phrases from the original
- Neither should add information or change the original meaning
- Over-quoting suggests you have not engaged with the material — paraphrase when possible
