Core Strategies for Lexical Resource
- Master Paraphrasing: Never repeat the exact words from the IELTS Writing task prompt. Use accurate synonyms to demonstrate linguistic flexibility and avoid repetition penalties.
- Focus on Collocations: Examiners actively listen for natural word pairings. For example, using 'commit a crime' is mathematically correct, whereas 'do a crime' sounds unnatural.
- Context is Crucial: Using overly complex words incorrectly will lower your score. Always verify the exact contextual usage, word class, and pronunciation using a trusted academic source like the Cambridge English Dictionary.
