API Product Description

The Intermediate Thesaurus is specially designed for students 5–8, ages 11–14, who want to enlarge their vocabularies and learn more about the English language. Newly added vocabulary pays particular attention to this age group in the areas of social media, technology, and entertainment. More than 150,000 word choices include synonyms, antonyms, related words, and idiomatic phrases.
