Answer:
A dictionary is the correct answer.
Explanation:
An atlas is incorrect because this type of book provides information about geography.
A thesaurus lists words according to the similarity of the meaning and it contains synonyms and antonyms instead of definition.
An encylopedia provides information about different topics, but it doesn't give definitions.
A dictionary is the correct answer because it offers the definition of the word, a guide to pronounce it, and the category of the word.
