1,200 words for the 2026 TOEFL, in three tiers and 30 themes, each with a short definition. Start with the words you cannot yet use, and open any theme for a full table and a self-check quiz.

Test Ninjas Research · Updated October 1, 2026

The TOEFL draws its texts from two worlds: everyday campus life — notices, emails, conversations about deadlines and lost files — and academic study, from ecology to economics. This list follows the same split. The easy tier covers campus life, the medium tier the general vocabulary of academic subjects, and the hard tier the precise and specialist words that make advanced passages dense.

This is an original Test Ninjas study list, not an ETS word list, and the tiers are our own study levels. Each definition gives one useful sense; many words have others.

How to study a vocabulary list

  1. Pick one theme at a time. Words that belong together are easier to remember together.
  2. For each unfamiliar word, read the definition, say the word aloud and write one sentence about your own study life.
  3. Learn related forms together — analyze, analysis, analytical — without counting each as a new word. The word formation guide shows the patterns.
  4. Notice which words go together, such as conduct an experiment. See TOEFL collocations.
  5. Test yourself after one day, a few days and a couple of weeks. The quiz on each theme page and the flashcards are built for this.

All 30 themes

Frequently Asked Questions

No. ETS does not publish a TOEFL vocabulary list. This is an original Test Ninjas study list, chosen to cover the campus and academic situations the published task descriptions describe. The definitions were written for this list.

There is no fixed number, and no list can cover every word you might meet. This list is a focused starting set of 1,200 high-value words. Broad reading and listening, plus the ability to guess meaning from context, do the rest.

They are study levels within this list, not ETS or CEFR levels. Easy words are everyday campus language, medium words are general academic vocabulary, and hard words are precise or subject-specific terms that are mostly worth recognizing.

Start with any easy words you do not know well enough to use, then work through medium themes that match subjects you find hard to follow. Leave the hard tier until the first two feel comfortable.

Yes and no. Complete the Words asks you to restore partly missing words in a passage, so spelling and word form matter. Elsewhere, vocabulary is tested indirectly: you need it to understand what you read and hear, and to express ideas precisely.
