This unique approach to words and wordlists is a more accurate reflection of the cumulative process required in order to ‘know’ a word. However, placing different senses of the same target word at different CEFR levels often makes these lists more complex to work with, in comparison to other well-known high-frequency wordlists such as Coxhead’s (2000) Academic Word List (AWL) and the new Academic Vocabulary List (AVL) developed by Davies and Gardner (2013).
