Paraphrasing and summarizing are very similar. Both involve taking ideas, words or phrases from a source and crafting them into new sentences. Whether paraphrasing or summarizing, you must always give credit to the original author.
Paraphrasing is expressing an author's ideas in your own words, by changing both the language and the sentence structure.
Paraphrasing is not easy. It is especially impossible to paraphrase something you do not really understand. If you don't understand it, you will be overly dependent on the words of your source. REMEMBER - when you paraphrase, you must cite the source. Even if you have not used the same words, you have borrowed ideas.
Summarizing also involves putting the author's ideas into your own words, but summaries omit much of the detail. A summary allows you to condense a significant amount of information into one or two sentences, using your own words. REMEMBER - when you summarize, you must cite the source. Even if you have not used the same words, you have borrowed ideas.
