You see the text, very interesting analysis and want to add it to your work. You see that the analysis is authorial, this text has an author, but since the text is written in another language, you translate this text into your own language. But do not forget, even if the text is translated from one language to another, it does not cease to belong to another author, even if you translated and paraphrased it.
We often hear that if they buy a paper from some author, then this work becomes rightfully their. Remember, that copyright allows you to own the text, but it does not allow you to pass off the text as your own, you are not the author, but the owner of the text.
