In 2000 Dr. Coxhead of Victoria University in Wellington researched and compiled a list of the most frequently used words in academic writing. For anyone undertaking academic studies, learn these words as you will most certainly come across them frequently in your readings and lectures. You will also most likely need to use them in your written assigments as well.
Here’s the Academic Word List to check for yourself. The List has 570 headwords with about 3000 words altogether including families falling under each headword.
