How does a glossary help in reducing redundancy?

A glossary is designed to create a single, clear, and consistent terminology for a project or document. By establishing one correct term for each item, it helps in reducing redundancy because it prevents the use of multiple terms to describe the same concept or item. When everyone involved in a project refers to the same term, it minimizes confusion and the potential for misunderstandings, ultimately streamlining communication. This consistency ensures that all stakeholders are aligned in their understanding, which is crucial for effective collaboration and requirement gathering.

The other choices may touch on different aspects of a glossary, but they do not effectively address how redundancy is specifically reduced. Distinguishing between homonyms and synonyms contributes more to clarity than to reducing redundancy itself, while defining requirements in a glossary clarifies understanding but could still lead to redundancy in references elsewhere if not sufficiently clear. Listing every term for the same item promotes confusion rather than clarity, which would more likely increase redundancy instead of decrease it. Hence, establishing one correct term for an item is crucial for maintaining coherence throughout the project documentation.
