A learner's thesaurus of over 15,000 words and expressions from written and spoken British and American English with CD-ROM. The learner's thesaurus helps students distinguish between similar words and use them correctly. The 2,000 entries: include between three and ten near synonyms, showing the differences between them in terms of meaning, grammar, register, collocations, and frequency; help students understand the differences between familiar words, such as easy and simple, while learning expressions they may not know, such as effortless, painless, and smooth sailing; provide over 4,000 notes to enable students to distinguish between very close synonyms, choose the best word for the context, and use it correctly; and include over 2,000 opposites.
