🧠 What Is Lexical Resource?
Lexical Resource refers to how well you use vocabulary in your IELTS Writing Task 2 essay. It includes:
Range — Do you use a variety of vocabulary?
Accuracy — Are the words used correctly?
Appropriateness — Do your word choices fit an academic essay?
You don’t need to use rare or “high-level” words — just the right words.
🚫 Common Vocabulary Mistakes
Using Vague Words
Words like people, things, stuff, or good don’t show control.
❌ Bad: Many people think this thing is good.
✅ Better: Many employees believe flexible hours improve productivity.
Use specific nouns whenever possible.
Over-Paraphrasing
Trying to paraphrase every word makes your writing awkward.
❌ Bad: The proliferation of mankind’s offspring has resulted in educational dilemmas.
✅ Better: Rising birth rates have led to challenges in education systems.
Only use synonyms you fully understand. Don’t force it.
Using Learned Phrases or Clichés
Examiners see phrases like “Every coin has two sides” or “Since the dawn of time” in nearly every exam. They won’t help.
✅ Use original, topic-relevant vocabulary.
✅ Keep it clear and purposeful.
Ignoring Collocations and Word Families
Natural vocabulary groups show control:
make a decision
reduce emissions
increase funding
environmental damage
You can also show range by using related word forms:
employ → employee, employment, unemployed
educate → education, educator, educational
Mixing Informal and Formal Tone
IELTS Writing Task 2 should always be formal and academic.
❌ Bad: A lot of kids drop out of school.
✅ Better: Many students leave education before completing secondary school.
Avoid slang and casual language: kids, tons of, loads of, a bunch of, stuff, etc.
Mixing British and American Spelling
❌ organise + center = Band 6
✅ organise + centre = Band 7+
Stick to one spelling system, preferably British. This site uses UK English.
