What term refers to a systematic arrangement of words that represent a concept or idea?

The term that best describes a systematic arrangement of words representing a concept or idea is a "Word web." A word web visually organizes and categorizes related terms, showing how different concepts connect to a central idea. It allows individuals to explore relationships among words and concepts systematically, facilitating deeper understanding and retention of the information.

In contrast, a graphic organizer serves a broader function and can include various formats, including charts and diagrams, but is not specifically limited to word relationships. A mind map is similar in concept but generally emphasizes a branching structure that showcases ideas radiating from a central idea rather than focusing exclusively on word relationships. A vocabulary list, while useful for understanding and memorizing words, does not provide the same visual representation of relationships and connections that a word web offers.
