Glossary builder for a topic

Build a glossary of the key terms someone needs to understand {{topic}}. Aim for {{n}} terms. For each term: the term itself, a one-sentence plain-English definition, an example of how it's used, and a 'related to' link to other terms in the glossary. Order alphabetically. Skip terms that are obvious to anyone in the field — focus on the ones that genuinely confuse newcomers.
