An unabridged dictionary is a comprehensive reference tool that contains all the words of a language with their meanings, origins, and examples. However, there are other words that can be used to describe an unabridged dictionary. For instance, a complete dictionary, comprehensive lexicon, or a thorough vocabulary guide. Alternatively, it can be referred to as an exhaustive dictionary, all-inclusive reference book, or a full-fledged dictionary. Additionally, it can also be called a comprehensive wordbook, a total word list, or a complete vocabulary directory. In essence, an unabridged dictionary is a valuable resource for anyone seeking to understand the nuances and intricacies of a language.
