A thesaurus is a kind of dictionary that places words of similar meaning side by side, helping you choose the most suitable word for what you want to say or write. It also helps you come up with different words that carry the same meaning instead of repeating the same word in a text, making your writing richer and more eloquent. This dictionary is suitable for primary-school pupils, helping them develop the skills they need to use synonyms in their writing. It is also an important tool for enriching children’s vocabulary and adding variety and vitality to their expression. The words were chosen from common vocabulary in children’s books, school curricula, and spoken and written language, and the dictionary is enhanced by attractive illustrations that help explain the words.
