In academic writing, which term refers to a brief marker or abbreviated alphanumeric notation embedded within the body of a text that points to a full entry in the reference list?

### Why this is right A **citation** is a marker in the main text that directs the reader to the source’s full details in the reference list. It may use an author’s name and publication year, a number, or another brief format, depending on the citation style. That link between a short marker and a full source entry is what the question describes. ### The concept An **in-text citation** appears where borrowed ideas, evidence, or quotations are used. The reference list at the end gives enough information to identify and find each cited source. A marker may use letters, numbers, or both; the important point is that it points to a full source entry. The other terms refer to different parts of a text: an index helps readers locate topics, an abstract summarizes a whole work, and a glossary explains selected terms. They do not identify sources used in the text. | Term | Purpose | |---|---| | Citation | Links a statement in the text to a source | | Index | Helps readers find topics and page locations | | Abstract | Briefly summarizes a work | | Glossary | Defines selected terms | ### The other options - **B. Index**: An index lists topics and where to find them, often by page number. It is tempting because it points readers elsewhere in a document, but it does not point from a claim to a source. - **C. Abstract**: An abstract briefly summarizes a paper or other work. It describes the work rather than identifying the source behind a particular statement. - **D. Glossary**: A glossary defines selected words or technical terms. It helps explain vocabulary, not document sources. ### Terms - **Citation**: A brief marker that connects material in the text to a source’s full details. - **Reference list**: A list, usually at the end of a work, containing the full details of sources cited in the text. - **Alphanumeric notation**: A marker made from letters, numbers, or both. - **Index**: An organized list of topics that helps readers locate them in a work. - **Abstract**: A short summary of a work’s purpose, approach, and main points. - **Glossary**: A list of selected terms with their meanings. ### Remember A citation points to a source, while an index points to a topic, an abstract summarizes a work, and a glossary explains terms.
