B2 Vocabulary: Collocations, Phrasal Verbs & Word Families

A strong B2 vocabulary is not a list of rare words. It is the ability to choose natural combinations, understand common phrasal verbs, recognise word families and adapt vocabulary to the situation. That is exactly why vocabulary affects so many parts of Cambridge B2 First: Part 1 and Part 3 of Use of English, Reading comprehension, Writing and Speaking.

If you are preparing with long alphabetical lists, change the system. B2 vocabulary becomes much easier to retain when you learn words as networks: collocation, grammar pattern, meaning contrast and example.

What kind of vocabulary does B2 First really reward?

Prioritise five categories:

1. Collocations — words that naturally occur together, such as make progress or highly recommended.
2. Phrasal verbs — especially common multi-word verbs whose meaning changes with the particle.
3. Word families — noun, verb, adjective and adverb forms used in Word Formation.
4. Dependent prepositions — combinations such as interested in, capable of or responsible for.
5. Functional language — phrases for comparing, recommending, speculating, agreeing, evaluating and giving reasons.

This gives you vocabulary that transfers across the exam instead of vocabulary that only looks impressive in a notebook.

Why are collocations more useful than isolated synonyms?

In Multiple Choice Cloze, four options can share similar meanings but only one may fit naturally with the surrounding words. That means memorising big = large = great = major is not enough.

Learn combinations such as:

• major problem;
• great success;
• large amount;
• big difference.

The meaning overlap is real, but the combinations are not freely interchangeable.

A useful flashcard therefore shows a phrase with one missing element. Front: ___ a complaint. Back: make a complaint + one example. This forces retrieval of the whole partnership.

How should you learn phrasal verbs at B2?

Avoid huge lists sorted alphabetically. Group phrasal verbs by meaning or topic:

Study/work: catch up with, hand in, put off, take on.

Relationships: get on with, fall out with, look up to.

Problems: deal with, sort out, run into.

Then add grammar information. Is the verb separable? Can a pronoun go in the middle? Does it need an object?

For example:

• turn down an offer;
• turn it down;
• not turn down it.

One short sentence that shows the grammar is more useful than a translation alone.

Word Formation: how should you build word families?

B2 First Part 3 rewards flexible word-building. Create families from real mistakes rather than copying an enormous suffix chart.

Always add negative forms when they exist. A common Part 3 trap is identifying the right part of speech but missing the negative meaning required by the sentence.

Practise the full decision: word class → positive/negative meaning → spelling change → collocation.

Which topic vocabulary is worth learning?

B2 texts frequently use broad everyday and social themes. Useful areas include:

• education and study;
• work and careers;
• travel and transport;
• health and lifestyle;
• technology and communication;
• environment;
• entertainment and culture;
• relationships;
• shopping and services;
• housing and cities.

Do not try to learn 100 words per topic. Build a compact set of reusable language: nouns, verbs, adjectives, collocations and two or three phrasal verbs.

For environment, for example, useful language might include reduce waste, renewable energy, public transport, environmentally friendly, raise awareness, cut down on plastic. Those phrases can appear in Reading and can also be used naturally in Writing and Speaking.

How can you make vocabulary active rather than passive?

Recognition is not enough. Many learners understand a word when reading but cannot produce it under exam pressure.

Use a four-step cycle:

1. Notice the phrase in a text or exercise.
2. Retrieve it later without looking.
3. Produce your own sentence.
4. Transfer it into a different context a few days later.

If you learn take something for granted, first record the original example. The next day, write a new example about technology. Later, use the phrase in a speaking answer or short paragraph. Each transfer strengthens access.

What should a useful vocabulary notebook look like?

Avoid one word per line. Use columns:

This format captures what the exam needs: not only meaning, but how the language behaves.

How do you use reading to build B2 vocabulary?

Reading is one of the best sources because it shows words in authentic relationships. But highlighting everything creates noise.

After reading a text, keep only items that meet at least one condition:

• they appeared more than once;
• they solve a problem you often have in Writing or Speaking;
• they form a useful collocation;
• they belong to a productive word family;
• they are common enough to reuse soon.

Limit yourself to roughly five to eight high-value items from one text. Then test them later. Selection improves retention.

How do you use vocabulary in B2 Writing?

The aim is precision, not decoration. Replace vague language when a more exact, natural phrase helps the reader.

Instead of things got better, perhaps the situation improved significantly fits a report. Instead of a very good film, a review might say an engaging, well-paced film.

But check collocation before sophistication. A tremendously delicious meal sounds less natural than an excellent meal. Simple and idiomatic beats unusual and forced.

Choose vocabulary by function: evaluation, comparison, cause, recommendation and qualification. That makes it easier to reuse across different topics.

How do you use vocabulary in B2 Speaking?

Speaking requires fast access. Prepare chunks, not scripts:

• One possible explanation is...
• I tend to think that...
• The main difference between the pictures is...
• It might be more suitable for...
• I see your point, but...

These chunks give you processing time while still sounding natural. Combine them with topic vocabulary rather than memorising entire answers.

A useful drill is 60-second speaking with a target list of five expressions. Use as many as fit naturally; ignore the rest. Forced vocabulary is not a success.

How should you review vocabulary for Use of English?

Use B2 Use of English practice to identify what your vocabulary study should contain. If you repeatedly miss Part 1 collocations, shift revision toward chunks. If Part 3 is weak, build word-family tables. If Part 4 exposes verb patterns, add them to your grammar-vocabulary notebook.

The exam itself should guide what you learn next.

A practical spaced-review schedule

A simple schedule works well:

• Day 0: learn the item in context;
• Day 1: retrieve without notes;
• Day 3: create a new example;
• Day 7: mix it with other items;
• Day 14: use it in writing or speaking;
• Day 30: quick final retrieval.

You do not need perfect intervals. The important part is returning to vocabulary after some forgetting has occurred.

Common B2 vocabulary mistakes

• learning translations without collocations;
• memorising too many words and reviewing too few;
• using a thesaurus to force “advanced” synonyms into Writing;
• ignoring dependent prepositions;
• learning phrasal verbs without separability or object patterns;
• forgetting negative prefixes in word families;
• recognising vocabulary but never producing it;
• collecting words that are too specialised to reuse.

Final takeaway

Build B2 vocabulary around useful relationships: word + collocation, verb + particle, adjective + preposition, root + word family, phrase + communicative function. Learn fewer items, retrieve them repeatedly and use them in new contexts. That approach improves not only vocabulary questions but also your Reading speed, Writing precision and Speaking fluency.
