You commit plagiarism when you use another person's words or ideas without crediting them, which is a serious academic offense that could get you dismissed from school. The best way to avoid plagiarism is to cite your sources and cite them properly.
A citation is a reference to the source of an idea or piece of information. Your citation should allow anyone who sees your reference list to be able to find the source. Citations include information such as author, title, date, website URL, etc .Whenever you get information from a source, quote it, or base your ideas on another person's work, you must document the source you used in an accepted citation style.
There are two basic ways to cite in-text (in the body of your paper). You can use quotations to copy exact words or you can paraphrase and summarize ideas from the source
