What word describes a reference to another source within a text?

• A. Citation
• B. Bibliography
• C. Appendix
• D. Index

Answer: (A)

The main idea here is the word for an in-text reference to a source. A citation is the act of pointing to where information came from within your writing, so readers can see the source and verify or explore it further. It functions as attribution and a path to the full details in the bibliography or works cited. The other terms describe different things: a bibliography is a list of sources at the end of the work, not the reference itself; an appendix is extra material added at the end; an index is a tool to find topics throughout the document. So the term that best fits describing a reference to another source within the text is citation.
