When preparing for IELTS Writing Task 2, many test-takers ask the same question: “Can I use idioms in academic writing?” The short answer is yes, but only if you use the right type.
The IELTS exam rewards candidates who demonstrate a wide range of vocabulary, but your language must also be appropriate for an academic essay. That’s where idiomatic but academic phrases come in—they help you sound natural, polished, and sophisticated without crossing the line into informal English.
In this post, we’ll explore what these phrases are, how to use them effectively, and provide examples, common mistakes, and top strategies for scoring Band 7 and above.
What Are Idiomatic but Academic Phrases?
These are natural-sounding expressions commonly used in formal and semi-formal writing. They are not clichés or slang, but they reflect idiomatic usage and maintain an academic tone.
Examples:
- “At the heart of the issue…”
- “It is worth noting that…”
- “There is no denying that…”
- “A case in point is…”
- “This raises the question of…”
These phrases improve the flow and clarity of your writing, while showcasing your lexical resource.

- “It is widely acknowledged that…”
- “There is growing concern about…”
- “The issue of ___ has sparked considerable debate.”
2. Adding Emphasis or Importance
- “At the heart of the matter lies…”
- “This is particularly true in the case of…”
- “What is more,…”
- “It is worth emphasizing that…”
3. Providing Examples or Evidence

Sample IELTS Task 2 Use
Question: Some people think that governments should invest in public transportation. Others believe more should be spent on road infrastructure. Discuss both views and give your opinion.
Sample Paragraph:
It is widely acknowledged that traffic congestion is a growing issue in many urban areas. A case in point is Manila, where daily commutes often exceed two hours. While some argue that expanding road networks could alleviate this, there is no denying that improved public transport would have a longer-lasting impact. In light of the above, it seems logical that governments prioritize mass transit development.
