Do I still need a citation if I changed all the words?

Yes. Even if you use entirely your own words and sentence structure, the underlying idea, data, or concept still belongs to the original author. Failing to cite the source of the idea is a form of plagiarism.

How is paraphrasing different from summarizing?

Summarizing involves taking a large amount of text, like a whole chapter, and condensing it down to its main points. Paraphrasing focuses on a smaller section of text, like a sentence or paragraph, and rewrites it in roughly the same length as the original.

Is it okay to keep key terms the same?

Absolutely. You do not need to find synonyms for universally accepted terms, proper nouns, or specific scientific jargon (like 'photosynthesis' or 'industrialization'). Changing these can actually make your writing confusing.

How do you avoid plagiarism when paraphrasing?

To avoid plagiarism when paraphrasing, you need to change both the words and the sentence structure of the original text, while keeping the original meaning. Simply swapping a few words for synonyms is not enough; you must completely digest the idea and explain it as if you were talking to a friend. Even after you have put the idea entirely into your own words, you still must provide a citation. Paraphrasing borrows someone else's intellectual property, so giving credit to the original author is always mandatory.

What makes a good paraphrase?

Think of a good paraphrase like taking a famous pop song and covering it in a completely different genre, like jazz. The core melody (the main idea) is still recognizable, but the instruments and tempo (your words and sentence structure) are completely your own. A precise paraphrase captures the author's exact meaning without mimicking their voice. It proves to your teacher that you actually understand the research, rather than just copying it.

The trap of patchwriting

Where most students slip up is a mistake called 'patchwriting.' This happens when you copy a sentence and just use a thesaurus to swap out a few adjectives or verbs. Patchwriting is still considered plagiarism because you are stealing the author's unique sentence structure and original syntax. If your sentence looks like a fill-in-the-blank version of the original, it is too close and needs to be rewritten.

The read-cover-write method

The best way to avoid patchwriting is to use the 'read-cover-write' method. First, read the passage you want to paraphrase until you fully grasp it. Second, cover the text or close the tab so you can no longer see the original words. Third, write the idea out in your own words. Finally, compare your version to the original to ensure you did not accidentally borrow their phrasing and that you captured the meaning accurately.

Worked through

Original text: 'The rapid industrialization of the 19th century led to unprecedented urban growth, as millions of people migrated from rural farms to cities in search of factory work.' Write a proper paraphrase of this sentence.

A poor paraphrase (patchwriting) would be: 'The quick industrialization of the 1800s caused massive city growth, because millions of individuals moved from country farms to towns looking for manufacturing jobs.' (This just swaps synonyms). A good paraphrase would be: 'During the 1800s, the boom in manufacturing drew massive crowds of rural workers into urban areas, causing cities to expand rapidly.' (This changes the structure, starting with the time period and reordering the cause and effect, while keeping the original meaning).
