The Open Dictionary is an innovative online lexicon that encourages public collaboration in defining language. Unlike traditional dictionaries, it invites users to contribute new entries, edit existing definitions, and enhance the richness of the English language. With a vast repository of over 400,000 words, the platform also features an extensive collection of 3,300 phrasal verbs and more than 1,600 idioms, making it a comprehensive resource for language learners and enthusiasts alike.

The Open Dictionary offers a wealth of grammatical resources, covering topics such as the use of adverbials, articles, and various verb forms, including the imperative mood and passive voice. It also provides tools for language experimentation, including a ‘Word of the Day’ and ‘Idiom of the Day,’ promoting better understanding of current English usage. Developed by Whoopa Projects, this platform stands as a democratic approach to language, reflecting the evolving ways in which English is spoken and understood.
