Why vocabulary matters on the IELTS
Matching Headings and Sentence Completion tasks heavily rely on paraphrasing. Knowing academic synonyms is essential for recognising when a question stem restates passage content.
Lexical Resource accounts for 25% of your Writing score. Examiners reward a wide range of accurate vocabulary; repetition and basic words keep you below Band 6.
Candidates who command topic-specific vocabulary speak more fluently and with fewer hesitations, which directly impacts both Lexical Resource and Fluency & Coherence scores.
Tip: When you encounter an unfamiliar word in a Reading passage, use surrounding context clues before consulting a dictionary. IELTS Sentence Completion tests whether you can infer meaning from context, not isolated recall.
