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

• 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.

Vocabulary for B1/Intermediate

• Opinion & argument: I believe, in my opinion, it depends on, although, however
• Abstract concepts: opportunity, responsibility, environment, relationship
• Emotions refined: disappointed, frustrated, relieved, grateful (not just happy/sad)
• Wider phrasal verbs: come up with, look forward to, get along with

B1 vocabulary = ~2,500–4,000 words. Opinion language, abstract nouns, news vocabulary, refined emotions, more phrasal verbs. The level where small talk becomes real conversation.

Focus: discourse markers (however, although, therefore), opinion verbs (believe, consider, assume), and the abstract nouns that let you discuss ideas, not just things.

B1 | Intermediate

• ✅ If I had more time, I would travel more. — second conditional
• ✅ The bridge was built in 1920. — passive voice
• ✅ She said she was tired. — reported speech with backshift
• ✅ Although it rained, we enjoyed the trip. — complex sentence with concession

These are B1 patterns — the CEFR intermediate level. At B1 you link ideas, use passive voice, handle reported speech, and manage second conditional — enough for travel, work basics, and everyday independence.

Marker: if you can explain why something happened and follow a news story, you're B1.

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.
