The correct answer is False
Step-by-step explanation:
A thesaurus similar to a regular dictionary contains the words of a language, but instead of providing their meaning, etymology and similar information most thesauruses only provide the synonyms or words related to another word and in some cases the antonyms of words. This means in a thesaurus it is possible to find alternative and contrasting words rather than the definition of it. In the same way, most thesauruses do not include information about the origin or etymology of a word as this is not directly related to the synonyms a word can have and this information is more likely to be found on etymological dictionaries or in regular dictionaries. Therefore, it is false a thesaurus gives the etymology of a word.
