You can reword an article without getting in trouble, but why? If you are giving visitors the same information they can get on another website, they have no incentive to read your article. People do it all the time, but it does not help their ranking.
We're not talking about article spinning, which is rewording sentences or paragraphs using automated software. The software substitutes synonyms for words so the original publisher can't claim duplicate content. Google may detect spun content if many bloggers use the same software to spin a popular article. There are only so many synonyms for certain words. Spun articles usually sound terrible. Rewritten articles sound much better, however, many people say rewriting someone else's work is just as unethical.
There are plenty of free article spinners online. Pasting text in and getting the result produces laughable phrases that a human visitor would have trouble understanding. The highest ranked article spinner in Google substituted gold dig for gold mine and win-win situation to success win circumstance. Any normal visitor would get a headache reading the results.
There are also rewording and rewriting tools online, some of which are free, that produce better results than article spinners. Several simplify text to make it easier for younger or ESL users to understand complicated text. These presumably have legitimate uses beyond getting free content.
Visitors want original content, but sometimes you will have the same ideas as other publishers. It's fine as long as you add an original idea, insight or opinion to your article. Many publishers get inspiration from multiple articles.
Writers can also use another person's research as long as they give credit to the original researcher with a link. The idea to to use only a small portion of their work and then give your own viewpoint about what their finding mean.
