The CEFR (Common European Framework of Reference) describes six levels of language ability, A1 to C2. The official descriptors talk about what you can do — "can understand the main points of clear standard input" — not how many words you know. But vocabulary is the raw material behind every can-do statement, and research has measured it level by level. This guide turns those measurements into targets, example words and study lists.

What the words look like at each level

Counts are abstract; the words themselves tell you where you are. These examples come straight from Word Hype's curated level pools.

A1–A2: the world around you

house, write, stone, guitar, carrot, budget, charge, credit, bother, beyond, fright. Concrete nouns, everyday verbs, the 2,000 most frequent words of English that cover roughly 80% of any ordinary text. At A2 the first abstract words appear (budget, credit) and phrasal patterns start (charge for, bother to).

B1–B2: talking about ideas

author, award, behave, category, reject, subsequent, talent, trouble, record, living. You move from things to relations and opinions. B2 is where the Academic Word List (570 families, ~10% of academic text) becomes essential and where most words gain a second meaning (record the noun and the verb, living as adjective and noun).

C1–C2: precision and nuance

deduce, dilemma, exceed, intuition, legislate, reconcile, scarcity, simulate, despair, ritual, bewitch. Lower-frequency, often Latinate, frequently with a Turkish/Spanish cognate that helps recognition but hides usage traps (reconcile with, not reconcile to, for people). At C2 the distinguishing skill is choosing between near-synonyms — scarcity vs shortage vs dearth.

How Word Hype assigns levels

Difficulty in the app is not word length. All three pools share the same 4–10 letter board range; what changes is the source pool. A1–A2 words come from high-frequency learner corpora; B1–B2 from mid-frequency bands and exam-preparation lists; C1–C2 from low-frequency bands cross-checked against advanced-learner evidence (the app's c-level-frequency-review). So "Hard" in Word Hype means "rare and useful", not "long".

How to find your level in five minutes

  1. Open the B1–B2 list. Cover the definitions and check the first 30 words: if you know 27+, move up; under 20, move down.
  2. Repeat with the neighbouring list. Your working level is the one where you miss roughly one word in three — the sweet spot for learning.
  3. Confirm with a quick read: an unknown word every ~10 words in a news article ≈ B1; every ~20 ≈ B2; every 50+ ≈ C1.

Moving up a level: what it actually takes

StepNew word familiesAt 5 words/dayFocus
A2 → B1~700–1,0005–7 monthsFrequency bands 2,000–3,000; phrasal verbs; past/future narration
B1 → B2~500–7003–5 monthsAcademic Word List; collocations; second meanings of known words
B2 → C1~500–1,0004–7 monthsLow-frequency band 4,000–5,000; register (formal/informal); precise synonyms
C1 → C2~500+4+ monthsIdiom, connotation, near-synonym choice; reading widely beats lists

Two things shorten every row. First, retrieval over rereading: test yourself instead of scanning lists (see The Science of Repetition). Second, varied contexts: meet each word in a definition, in audio, in a paragraph and in a dialogue — which is exactly what the four Word Hype modes do (see Repetition in Varied Contexts). If your goal is an exam, How many words do you need for IELTS? translates these levels into band targets.
