IELTS Vocabulary: 50 High-Scoring Words for Every Topic

Why Vocabulary Matters in IELTS

Lexical Resource accounts for 25% of your marks in both Speaking and Writing. But it's not just about knowing big words — examiners look for:

• Range: Using different words for the same concept (not repeating "good" 10 times)
• Precision: Choosing the right word for the context
• Collocation: Using natural word combinations ("make a decision" not "do a decision")
• Topic vocabulary: Using words relevant to the topic being discussed
