Subtopic

A subtopic is a topic that forms a subdivision of a larger topic. Subtopics help break complex subjects into manageable parts, clarifying scope and guiding research, writing, and information organization.

Subtopics are typically defined by key concepts, aspects, or questions that characterize the broader topic. They are usually arranged hierarchically: a main topic serves as the parent and each subtopic as a child; subtopics may themselves be subdivided into sub-subtopics to reflect increasing specificity.

In practice, subtopics are used in education, research, content development, and knowledge management. They improve readability, navigation, and comprehension by allowing readers to scan a topic quickly and then focus on areas of interest. They also help ensure comprehensive coverage and facilitate indexing, search, and cross-referencing.

Examples: For the main topic climate change, subtopics might include greenhouse gases, physical impacts, mitigation strategies, adaptation, economics, and policy. In a wiki or outline, subtopics are often linked to related subtopics to reflect relationships and to aid navigation.

Best practices: keep subtopics distinct and non-overlapping, match the level of detail to the main topic, avoid unnecessary fragmentation, and maintain consistent scope across subtopics. When appropriate, connect subtopics with cross-links to related areas and provide sources.
