Indexy is a plugin for WordPress that lets you create a glossary of terms, write definitions, and highlight those terms inside your posts. Visitors can hover over any highlighted terms to see a short excerpt, or click them for the full definition. As an author, you get several shiny shortcodes to enhance your website, as well as widgets to show off your glossary and make navigation easy. Using Indexy, you can create glossary pages, which function similarly to regular posts or pages in WordPress. In addition to the title of the article, you can define any number of synonyms. Whenever any of the terms come up in a page or blog post, they will be highlighted according to the rules set in the plugin’s options.
