TOEFL Vocabulary That Actually Transfers to Score

TOEFL vocabulary should be learned in academic patterns: cause and effect, contrast, classification, research methods, change over time, and evidence. These patterns appear in Reading passages, Listening lectures, Speaking tasks, and Writing responses.

Do not only memorise definitions. For each word, learn one collocation and one sentence frame. For example, indicate becomes the data indicates that..., and consequence becomes an unintended consequence of.... Those frames make the word usable under time pressure.

Vocabulary Targets by TOEFL Goal

For TOEFL 80+, focus on high-frequency academic words and lecture signal language. For TOEFL 90+, add paraphrases and topic vocabulary for education, science, environment, history, psychology, and campus life. For TOEFL 100+, practise using the words actively in Speaking and Writing instead of only recognising them in Reading.
