The Note Definitions plugin allows users to create and manage a personal dictionary within Obsidian by defining words and phrases across their notes. It enables users to store definitions in dedicated folders, with options to preview, add, and edit definitions via commands or context menus. Definitions can be structured in consolidated files with multiple entries or atomic files with single entries, offering flexibility in organizing content.

The Obsidian Wordnik Definitions plugin allows users to seamlessly fetch and insert dictionary definitions, synonyms, and related word data into their notes. By leveraging the Wordnik API, users can retrieve data for a specified search term or the title of the current note. The plugin offers customization options, including templates for formatting extracted data and limiting the number of definitions displayed. This provides a convenient way to enhance notes with rich lexical information directly within the Obsidian workspace.
