Vocabulary

TOEFL vocabulary: recognition is not enough

A word you recognise on a flashcard and a word you can produce under time pressure are two different pieces of knowledge. The 2026 test asks for the second one.

In short

The 2026 TOEFL tests vocabulary in a way flashcards do not prepare you for. Complete the Words asks you to supply a missing word from context with only its opening letters shown, and Listen and Choose a Response depends on recognising idiom and register in a single spoken line. Both require production — being able to write or say the word — rather than recognising it in a list.

Where vocabulary is actually scored

Complete the Words — you produce the word. Recognition gives you nothing here.
Listen and Choose a Response — idiom, register and set phrases decide the answer more often than individual words do.
Read in Daily Life — practical, institutional vocabulary: deadlines, deposits, eligibility, notices.
Writing — precision costs you a band when it is missing, whatever the grammar looks like.

What to learn

The bank runs to 3,133 words across 22 themes, weighted toward the subject areas TOEFL passages and talks actually keep returning to. This is the real distribution, not a wish list:

3,133 words across 22 themes

Core academic language	596
Economy & society	326
Psychology	235
Daily life	203
Idioms	201
Technology	164

History	97
Housing	75
General academic	74
Transport	61
Astronomy	48
Economics	24
Dining	17
Shopping	15
Health	15

Core academic language dominates deliberately. The verbs and nouns that structure an argument — *allocate*, *duration*, *accommodate* — appear in every subject area, so they earn their place ahead of any single field's terminology.

What a word entry looks like

Every entry carries the part of speech, the pronunciation, a CEFR level so you can tell what is worth your time at your band, a definition in plain English, the collocations the word actually appears in, and a sentence using it. Six real entries from the bank:

abandonv./əˈbændən/B2

to leave a person, place or plan completely

The team had to abandon the field study when the storm hit.

abandon a planabandoned building

collaboratev./kəˈlæbəreɪt/B2

to work together with others to achieve a shared goal

Engineering students must collaborate with business majors on a joint project this semester.

collaborate closelycollaborate on a project

deceivev./dɪˈsiːv/C1

to make someone believe something false

The calm surface deceived the swimmers.

deceive sb intoappearances deceive

kettlen./ˈketl/B1

a container for boiling water

The kettle takes four minutes on this stove.

obsoleteadj./ˌɑːbsəˈliːt/C2

no longer used because something newer has replaced it

The technique became obsolete within a decade.

become obsoleteobsolete equipment

saturatedadj./ˈsætʃəreɪtɪd/B2

describing a type of fat that is linked to raising cholesterol

Foods high in saturated fat can raise cholesterol and harm the heart.

The CEFR level matters more than it looks. At band 4 (B2) the B1 and B2 entries are what move your score; grinding C1 vocabulary before the B2 layer is solid is the most common way to spend weeks and gain nothing.

A drill that tests production, not recognition

PrepScore rotates three modes over the same word bank: fill the gap in a real sentence, write the word from its meaning, and hear it and spell it. Hints shrink as you get more familiar — first letter and length, then length only, then nothing. A word counts as mastered only after you produce it correctly twice in a row, so "mastered" means something you can actually do.

Why two in a row

One correct answer can be a lucky guess from a first letter. Two consecutive productions, spaced across days rather than within one session, is the cheapest test that separates knowing a word from having just seen it.

Practise the 2026 format, not the old one

Every task type in the current test, a full explanation on every question, and a band estimate that shows where your next half band comes from.

Vocabulary by theme

Each theme has its own page with real entries from the bank — definition, pronunciation, CEFR level, collocations and a sentence using the word.

How many words do I need for the TOEFL?

There is no official list, and a raw count matters less than what kind of knowledge you have. A few thousand words you can produce beats a much larger list you only recognise, because Complete the Words and the writing tasks both require production.

Are flashcards enough for TOEFL vocabulary?

They build recognition, which helps in Reading and Listening comprehension but does not cover Complete the Words or writing precision. Pair them with a production drill that makes you write the word.

Does PrepScore have a TOEFL word list?

Yes — a themed bank covering campus life, general academic language, and the science and social-science areas the test keeps returning to, drilled by production rather than recognition.
