#How to Learn This Vocabulary Effectively
- Learn collocations, not isolated words. "Commit a crime" not "do a crime." "Pose a threat" not "give a threat."
- Use new words in writing immediately. Write practice sentences the same day you learn a word.
- Review using spaced repetition. Review words after 1 day, 3 days, 7 days, and 14 days.
- Group words by topic. When you encounter an IELTS essay about the environment, you want to recall a cluster of related words, not random individual terms.
- Do not learn synonyms in isolation. "Big" and "substantial" are not interchangeable in all contexts. Learn when to use each word.
