Dictionaries

According to the Cambridge dictionary, “dictionary” means a book that contains a list of words in alphabetical order with their meanings explained or written in another language, or a similar product for use on a computer.

Taking this into consideration, I’ve researched for different kinds of English dictionaries like pictionaries, idiom dictionaries, thesaurus (a type of dictionary in which words with similar meanings are arranged in groups), urban dictionaries and so forth. Below you’ll find a list of the ones I liked the most.
