Work with a Thesaurus

In this worksheet, students will learn what the term 'synonym' means and how a thesaurus can improve the range of vocabulary students use in written prose.

Worksheet Overview

A thesaurus is a type of dictionary that can help us improve our vocabulary.


A thesaurus is very useful when we want to improve an adjective (describing word) that we have used in our writing.


A thesaurus contains synonyms and antonyms that can help us to increase the range of vocabulary we use.



Synonyms are words that mean the same as the current adjective being used.



Synonyms of big  = gigantic, huge, massive, enormous.



Antonyms are words which mean the opposite of the adjective currently in use.



Happy = sad, devastated, miserable, unhappy.


For this activity, it will help if you use a paper or online thesaurus.


A thesaurus is arranged like a dictionary, in alphabetical order.
