indictionary
Indictionary refers to a hypothetical or conceptual dictionary that contains all words in existence, including archaic, obsolete, technical, neologisms, and potentially even invented words, across all languages and dialects. It is not a single, published work but rather an abstract idea representing the totality of human vocabulary. The concept of an indictionary often arises in discussions about language, lexicography, and the limits of linguistic documentation.
The creation of a true indictionary is practically impossible due to the dynamic and ever-expanding nature
In fictional contexts, an indictionary might be depicted as a magical artifact or an advanced artificial intelligence
