- Collocations are the key differentiator between B2 and C1-C2 level English production.
- Learn new vocabulary in collocational clusters, not as isolated words.
- Verb + noun collocations (make a decision, raise awareness) are the most productive type to study.
- Use corpus tools like COCA and BNC to verify collocations in authentic English.
- Extensive reading in authentic English is the most efficient long-term collocation acquisition strategy.
If you have reached B2-C1 level in English, you have acquired enough grammar and vocabulary to communicate clearly. Yet something still makes your English sound slightly "foreign" to native speakers — and that something is almost always collocations. While you might correctly say "do a mistake" or "make a research", a native speaker would immediately sense that something is wrong, even without being able to say exactly why.
Collocations — the natural word partnerships that English speakers use instinctively — are one of the final frontiers of advanced fluency. This guide covers the most important collocation types, the most common errors at C1-C2 level, and the most effective strategies for acquiring them rapidly.
1. What Are Collocations?
A collocation is a combination of words that co-occur in natural language more frequently than chance would predict. They are not idioms (whose meaning is non-literal) but word partnerships that have become conventional through usage. The key feature of a collocation is that substituting a synonym of one word often produces an unnatural result:
- heavy rain — correct; strong rain — unnatural
- make a decision — correct; do a decision — unnatural
- commit a crime — correct; perform a crime — unnatural
- raise awareness — correct; elevate awareness — unnatural
Collocations exist on a spectrum from very free (open/close/lock the door) to semi-fixed (conduct/carry out/undertake research) to fully fixed (compound interest, blind spot). Studying them from authentic sources ensures you learn the full range of natural variation. Explore LexFizz vocabulary exercises to practise collocational chunks.
2. Types of Advanced Collocations
At C1-C2 level, you need to master multiple collocation types. The most productive types to study systematically are:
| Type | Pattern | Examples |
|---|---|---|
| Verb + noun | verb + object noun | draw a distinction, pose a threat, reach a consensus |
| Adjective + noun | modifier + head noun | stark contrast, profound impact, legitimate concern |
| Adverb + adjective | intensifier + adjective | deeply concerned, highly significant, fundamentally different |
| Noun + verb | subject noun + verb | tensions rise, pressure mounts, debate rages |
| Noun + noun | compound or genitive | policy framework, risk assessment, core competency |
| Verb + adverb | verb + manner adverb | strongly suggest, flatly deny, broadly agree |
3. Verb + Noun Collocations at C1-C2
Verb-noun collocations are the most frequently tested category in Cambridge Advanced (CAE) and Proficiency (CPE) examinations, and the most likely source of errors in written and spoken production. The challenge is that English often uses a light, general verb (make, take, give, do) rather than a specific verb:
| Key verb | Collocates | Avoid |
|---|---|---|
| make | make a decision, make progress, make an effort, make an exception, make a point | do a decision, do progress |
| take | take action, take responsibility, take precedence, take its toll, take into account | do action, make responsibility |
| draw | draw a conclusion, draw a distinction, draw attention to, draw on experience | make a conclusion, do a distinction |
| conduct | conduct research, conduct an interview, conduct a survey, conduct an investigation | make research, do an investigation |
| raise | raise awareness, raise concerns, raise the question, raise standards | elevate awareness, increase concerns (often wrong) |
When you learn a new noun, immediately find 3 verbs that collocate with it. For "decision": make a decision, reach a decision, reverse a decision. Record them together in your vocabulary notebook. This triples your productive vocabulary for each new word.
4. Adjective + Noun Collocations
Adjective-noun collocations at C1-C2 level include many cases where a common adjective must be replaced by a stronger, more precise synonym to sound natural. This is where learners who rely on simple vocabulary sound noticeably non-native even at advanced level.
| Collocation | Meaning | Example sentence |
|---|---|---|
| stark contrast | very noticeable difference | "This stands in stark contrast to previous findings." |
| profound impact | deep, significant effect | "The policy had a profound impact on public health." |
| legitimate concern | justified worry | "This raises a legitimate concern about data privacy." |
| sweeping generalisation | overly broad claim | "That is a sweeping generalisation that ignores the data." |
| bitter dispute | intense, angry disagreement | "The two parties were locked in a bitter dispute." |
| inherent risk | built-in, unavoidable danger | "There is an inherent risk in any surgical procedure." |
5. Academic and Professional Collocations
Many C1-C2 learners need English for academic or professional contexts where register-specific collocations are essential. Using informal collocations in formal writing (or vice versa) signals register mismatch even when the meaning is correct. See our guide to academic English for researchers for more context.
| Context | Key collocations |
|---|---|
| Academic writing | address the question, highlight limitations, identify patterns, challenge assumptions, inform policy |
| Business | streamline operations, mitigate risk, drive growth, leverage expertise, align with objectives |
| Law | exercise discretion, discharge a duty, bring a claim, infringe a right, uphold a principle |
| Media/journalism | allegations emerge, controversy surrounds, tensions escalate, deal falls through, talks collapse |
6. How to Learn Collocations Effectively
The key principles of effective collocation acquisition are: learn in context, learn in clusters, review with spaced repetition, and confirm with corpus tools. Random word lists are far less effective than contextualised examples because the brain stores collocations as single units, not as two separate words that happen to appear together.
- Corpus checking: Use COCA (corpus.byu.edu) or Skell to verify any collocation you are unsure of before using it in formal writing.
- Collocation notebooks: Record each new word with its most frequent collocates and an example sentence.
- Spaced repetition: Use Anki flashcards with collocations as the target, not isolated words. Show the verb, elicit the noun collocate.
- Extensive reading: Read widely in authentic English — quality journalism (The Economist, The Guardian), academic articles in your field, and literary fiction — noticing and recording collocations.
- Exercises: Use LexFizz exercises focusing on word combinations and gap-fill tasks that target common collocations.

What are collocations in English and why do they matter at C1-C2?
A collocation is a pair or group of words that naturally occur together more frequently than chance would predict. At C1-C2 level, correct collocation use is one of the most reliable markers of near-native fluency. Native speakers process collocations as chunks, so using the wrong collocation immediately signals non-nativeness even when the grammar is correct.
What is the difference between a collocation and an idiom?
Collocations are word combinations whose meaning is transparent from the individual words (e.g., "reach a conclusion" means to arrive at a conclusion). Idioms are fixed expressions whose meaning cannot be derived from individual words (e.g., "kick the bucket" means to die). C1-C2 learners need to master both levels, but collocations are far more frequent in everyday academic and professional communication.
What are the most important types of collocations for C1-C2 learners?
The most important types at advanced level are: verb + noun (take responsibility, draw a distinction, raise awareness); adjective + noun (stark contrast, profound impact, legitimate concern); adverb + adjective (deeply concerned, highly significant, fundamentally different); noun + verb (pressure mounts, tensions rise); and noun + noun (policy framework, risk assessment). Verb-noun collocations are the most productive single category to study.
How can I learn collocations more effectively?
The most effective method is to learn collocations in context. When you encounter a new word, record it with 2-3 common collocates: not just "problem" but "pose a problem, tackle a problem, underlying problem". Use a dedicated collocations dictionary (Oxford Collocations Dictionary). Use spaced repetition flashcards with example sentences. Notice and record collocations from authentic texts in your reading.
What are common collocation errors made by advanced English learners?
Common C1-C2 collocation errors include: "do a mistake" (should be: make a mistake); "make research" (should be: conduct/carry out research); "strong rain" (should be: heavy rain); "do a decision" (should be: make a decision). These errors often come from direct translation from the learner's first language, known as L1 transfer.
Are there collocations specific to academic or professional English?
Yes — register-specific collocations are essential at C1-C2. Academic collocations: conduct research, draw conclusions, address a question, identify patterns, highlight limitations. Business collocations: reach a consensus, streamline operations, mitigate risk, drive growth, leverage expertise. Legal collocations: bring a claim, exercise discretion, discharge a duty, infringe a right.
Can I use a corpus to find collocations?
Yes — corpora are one of the most powerful tools for discovering authentic collocations. Free corpus tools include: COCA (Corpus of Contemporary American English), BNC (British National Corpus), Skell (Sketch Engine for Language Learning), and iWeb Corpus. Enter a word and view its most frequent collocates in authentic text. This is especially useful for checking whether a collocation you have invented is actually used by native speakers.
How do fixed expressions differ from collocations?
Fixed expressions are fully fixed chunks: "by the way", "in spite of", "as a matter of fact". Collocations allow more variation: you can say "strong/close/intense relationship" but not "powerful relationship" in most contexts. At C1-C2, it is important to know which elements of an expression can be varied and which cannot — this requires extensive reading and active noticing.
What tools and resources help with learning collocations?
Key resources: Oxford Collocations Dictionary; Macmillan Collocations Dictionary; the COCA corpus at corpus.byu.edu; Ludwig.guru (sentence examples from verified sources); Netspeak.org for comparing phrase frequencies. For structured learning, Michael McCarthy's English Collocations in Use (Advanced) is the most comprehensive reference. LexFizz vocabulary exercises also target high-frequency collocations.
How long does it take to master English collocations at C1-C2 level?
Research suggests that acquiring strong collocation knowledge requires exposure to millions of words of authentic English text — which is why extensive reading is so important alongside explicit study. Targeted collocation study of 10-15 new collocations per week, combined with extensive reading in English, typically produces noticeable improvement in writing and speaking naturalness within 3-6 months at C1 level.
