Falsos Amigos is a vocabulary reference book designed to help English language learners avoid common mistakes caused by “false friends”—words in English and other languages (especially Spanish) that look similar but have different meanings. It highlights these confusing word pairs and explains their correct usage in clear, simple language. The book helps learners improve accuracy in both speaking and writing by building awareness of misleading vocabulary. Suitable for intermediate learners and above, it is useful for classroom support, exam preparation, or independent study to strengthen vocabulary precision and prevent common translation errors.
