Academic and IELTS words
In short
Long words that carry real weight in IELTS Speaking Part 3, academic writing and professional English. The failure is almost never the individual sounds; it is misplaced stress, on exactly the words you chose in order to show range.
The pattern
The suffix usually decides the stress: -ity, -ical and -ion pull stress onto the syllable immediately before them.

Frequently asked questions
What are the most common academic and ielts words in English?
This list covers 16: entrepreneur, questionnaire, environment, phenomenon, hierarchy, genre, hypothesis, bureaucracy, and more. Each has its own page with IPA, a syllable breakdown, audio in both accents, and a recording drill.
Is there a rule behind academic and ielts words?
The suffix usually decides the stress: -ity, -ical and -ion pull stress onto the syllable immediately before them.
Do I need to fix all of these for IELTS?
No. IELTS scores intelligibility, not word-perfect accuracy, and it accepts every standard accent. Fix the words you actually use, starting with the frequent ones: a mispronounced everyday word costs far more than a mispronounced rare one.
