Academic Collocation Checker

What are Academic Collocations?

Collocations are words that naturally go together in English. In academic writing, using the right collocations makes your essays, research papers, and reports sound more professional and natural.

For example, native speakers say "conduct research" instead of "do research", or "significant impact" instead of "big effect". Wrong collocations can lower your IELTS/TOEFL writing score or make university professors notice your English is not yet at the required level.

Why Use the Academic Collocation List (ACL)?

The ACL is a list of 2,469 high-frequency word combinations used in academic texts across all subjects. Mastering these collocations helps you:

• Reach B2/C1 vocabulary level faster
• Write more accurate and sophisticated essays
• Understand research papers and textbooks without a dictionary
• Improve IELTS Writing Task 2 and TOEFL integrated writing scores
• Sound more like a native academic writer
