How to avoid plagiarism:
You must give credit to the source when you cite the language and an idea.
1. Use direct quotes for the original language and add an in-text citation or footnote to point to the full citation/biliography at the end
2. Paraphrase the original text using your own language with an in-text citation or footnote and an end bibliography.
3. When you use someone's idea, you should give credit.
