The Dictionary plugin adds a dictionary view to Obsidian, allowing you to look up words and their meanings in various languages. With this plugin, you can access definitions, synonyms, and phonetics for over 15 languages, including English, Spanish, French, German, Italian, Chinese, Japanese, and more. The dictionary is fully customizable, with options to set your default language, use offline support, and choose from a range of third-party APIs to find definitions. You can also translate the plugin into new languages or add new API support to expand its functionality.
