I have to write the definition for a term in my Paper. I find the best definition for the term in a particular paper, say paper1. I would like to quote the definition as it is in my paper. I believe this is not wrong and is not plagiarism, as I am quoting the definition with proper references. Please correct me if I am wrong.
Now, the author of paper1 in her paper cites a paper for the definition, say paper2. But in paper2 I cannot find the exact wordings which I would like to quote, or else I could have quoted from paper2.
Now how do I quote this term definition. Do I need to cite both the papers or shall I put the quote with citation of paper2 as it is from paper1, and then cite paper1.
Please advise me what is the proper convention that is followed.
