a syndicated article is an article that you get from a syndicated like an rss feed. you can automatically post articles using syndicated articles on your website so that your website updates itself everyday, but don't ask me how to do that coz I don't know how
You can use a php script to do the job for example, but if copying articles, make sure you keep the proper attribution to the author and don't make it the only content of your page do avoid duplicate content issues.
