Vocabulary

  • A1: ~500–800 words (survival: family, food, numbers)
  • A2: ~1,500–2,500 (routine: work, leisure, basic phrasal verbs)
  • B1: ~2,500–4,000 (opinions, news, abstract topics)
  • B2: ~4,000–6,000 (register precision, hedging, idioms)
  • C1: ~6,000–10,000 (academic, register sensitivity)
  • C2: 10,000+ (literary, rare, full style range)

Vocabulary covers word-level practice: individual words, collocations, phrasal verbs, idioms. Organised by CEFR level. Grammar tells you HOW to build sentences; vocabulary gives you WHAT to put in them.

Collocations

  • make a decision — ❌ do a decision
  • strong coffee — ❌ powerful coffee
  • heavy rain — ❌ strong rain
  • highly unlikely — ❌ very unlikely (grammatical, but less natural)

Collocations are word pairs that English habitually puts together. Both options may be grammatically valid, but one sounds native and the other doesn't.

Pattern: there's no logic to predict them — you make decisions but do homework, you have strong coffee but heavy rain. They must be learned as chunks, not deduced from rules.

Vocabulary for A2/Elementary/Pre-Intermediate

  • Routine social: appointment, holiday, invitation, plan, weekend
  • Work & school: colleague, meeting, exam, homework, deadline
  • Basic phrasal verbs: get up, look for, turn on, put on, take off
  • Common collocations: make a mistake, do homework, have a shower

A2 vocabulary = ~1,500–2,500 words. Covers routine social life, work/school, leisure, basic phrasal verbs, and common collocations. The level where English starts feeling dynamic rather than just naming things.

Focus: high-frequency phrasal verbs (top 50), verb-noun collocations (make/do/have/take + noun), and the vocabulary of daily routines.

A2 | Elementary | Pre-intermediate

  • I went to the cinema yesterday. — past simple
  • I have visited Paris twice. — present perfect (life experience)
  • If it rains, I'll take an umbrella. — first conditional
  • You should see a doctor. — modal for advice

These patterns are A2 — the second CEFR level. At A2 you move past survival phrases into real grammar: past tenses, the present perfect, basic conditionals, and modals for advice/obligation.

Marker: if you can describe yesterday and give simple advice, but struggle with abstractions or nuance, you're at A2.

Easy

  • She is a teacher. — one verb form, one rule
  • I have two cats. — basic possession, short sentence
  • He doesn't like coffee. — simple negation with do-support
  • Only one answer is clearly correct; distractors are obviously wrong.

Easy marks beginner-level challenges: A1–early A2, one rule at a time, everyday vocabulary, no trick questions.

Use "Easy" when you want to build confidence on a specific rule without interference from other grammar or tricky contexts.
