Abhidhan (dictionary)  Etymologically, abhidhan means word-meaning, but, like western dictionaries, the abhidhan has expanded its functions and provides help with spellings, synonyms, usage, pronunciation, and grammar.

Many dictionaries provide an appendix covering necessary information of our day-to-day life, which sometimes acts as a guide-book.
