In English, we might ask someone to "cite their quotation", or observe that they have made a quotation but failed to cite it. This is, I suppose, a somewhat scholastic use of the term, meaning to indicate the provenance of a quotation (author, page, etc.).
Looking up these terms in French, one finds that both "quote" and "cite" are translated "citer", and the same thing happens with the substantive "citation".
What's the most natural way to distinguish these ideas in French? A paraphrase of "cite" as I gave above? A term not present in my dictionary?
