New Academic Word List 26-50

By Will SalisburyUpdated

These are words 26 to 50 of the top 400 words of the New Academic Word List: words that appear again and again in university texts and in the Academic IELTS Reading and Writing tasks. For each word, read the example, try to guess the meaning, then reveal it and mark honestly how you did. Then say the word aloud, record yourself and compare it with the model voice. When you have finished, try the gap quiz and save your results.

The New Academic Word List was compiled by Charles Browne, Brent Culligan and Joseph Phillips (2013) from academic texts, and its words are ranked by the authors. We teach the top 400 in rank order. How the list was made
