Common English Idioms Quiz
Do you know what it means to hit the nail on the head or let the cat out of the bag? Test your understanding of 20 common English idioms — their meanings, contexts, and real-world usage across B1–C1 level.
Start the Quiz →What This Quiz Covers
English idioms are fixed expressions whose meanings cannot be understood from the individual words alone. A learner who knows every word in it's raining cats and dogs will still be confused if they interpret it literally. Mastering idioms is therefore a key step in moving from intermediate to advanced fluency — they appear constantly in spoken English, journalism, podcasts, fiction, and professional writing.
This quiz focuses on the most widely used idioms across everyday conversation, the workplace, and academic English. Each of the 20 multiple-choice questions presents an idiom in a realistic sentence context and asks you to select the correct meaning from four options. Items are drawn from across the B1–C1 CEFR range, with a concentration at B2, so the quiz is challenging but fully accessible to motivated B1 learners working towards the next level.
A strong grasp of idiomatic language is rewarded in Cambridge B2 First, IELTS, and TOEFL speaking and writing tasks. This quiz helps you identify gaps quickly so you can target the specific idioms you need to study. Visit the vocabulary hub or the grammar hub for further practice resources.

How to Use This Quiz
Read each question carefully and pay close attention to the sentence that surrounds the idiom — context clues often help you narrow down the meaning even if you haven't encountered the idiom before. Select the answer that best describes what the idiom means in that specific situation, as many idioms have more than one possible interpretation depending on context.
After completing all 20 questions, review any that you answered incorrectly and note the idiom, its meaning, and a short example sentence of your own. Creating a personal idiom log — a dedicated section of your vocabulary notebook just for idiomatic expressions — is one of the most effective study strategies at B2–C1 level. Group idioms thematically (body parts, animals, colours) to make them easier to memorise. You can then practise the new idioms using the Flash Cards exercise or reinforce them with the Find the Match activity.
Aim to revisit this quiz in one week to check retention. Spaced repetition — reviewing new vocabulary at increasing intervals — significantly improves long-term recall of idiomatic vocabulary. Combine this quiz with authentic reading: news articles, podcasts, and graded readers all expose you to idioms in natural context, which accelerates acquisition far more than word lists alone.
For a broader vocabulary workout, explore the vocabulary hub where you can find themed word lists and exercises covering collocations, phrasal verbs, and more. If you want to understand how idioms connect to grammar structures, the grammar hub is a good companion resource.
Idioms in IELTS and Cambridge Exams
Idiomatic vocabulary is explicitly tested and rewarded in several major English proficiency exams. In the Cambridge B2 First (FCE) Use of English paper, Part 1 multiple-choice cloze and Part 2 open cloze frequently include idiomatic expressions and fixed phrases. The Speaking test rewards candidates who use idioms naturally without sounding rehearsed. Examiners at C1 Advanced (CAE) expect candidates to handle a far wider range of idioms and collocations with minimal effort.
In IELTS Speaking, the Lexical Resource band descriptor for Band 7 (B2–C1) states that candidates use "some less common and idiomatic vocabulary with some awareness of style and collocation." Band 8 adds "skilful use of uncommon lexical items." Using one or two well-chosen idioms fluently in a Part 2 long turn or Part 3 discussion is an effective way to demonstrate this range. Avoid forcing idioms into unnatural positions — one accurate, natural idiom outperforms three awkward ones every time.
For TOEFL iBT, idiomatic comprehension is important in the Listening section, where academic lectures and campus conversations include informal idioms. The Speaking and Writing sections reward precise, varied vocabulary — including fixed expressions — as indicators of advanced proficiency.

Frequently Asked Questions
An idiom is a fixed expression whose overall meaning is different from the literal meanings of its individual words. For example, kick the bucket does not describe physically kicking a bucket — it means to die. Break a leg does not literally advise injuring yourself — it is a way of wishing someone good luck before a performance. Because their meanings are non-compositional, idioms must be learned as whole units rather than word by word. English has thousands of idioms, and native speakers use them constantly in both casual conversation and formal writing.
Very common idioms such as under the weather or get the ball rolling appear at B1 level, but a systematic understanding of idiomatic language is expected from B2 onwards. The CEFR B2 descriptor explicitly mentions that learners can understand and use a range of idiomatic expressions. At C1, learners are expected to recognise a wide variety of idioms, colloquialisms, and fixed expressions and to use them flexibly and accurately. This quiz targets B1–C1, with most items pitched at B2 to challenge learners who are ready to move to an advanced level.
Usually no — idioms are fixed expressions and changing even one word breaks the idiom or makes it unrecognisable. You cannot say let the dog out of the bag instead of let the cat out of the bag. However, some idioms allow limited grammatical variation. For example, verb tense can change: she spilled the beans / he has been spilling the beans for years. A few idioms have well-established variants: bite the bullet and bite the bullet and get on with it are both natural. As a learner, the safest approach is to learn and use the standard form of each idiom until you are very confident in the language.
A phrasal verb combines a verb with a particle (a preposition or adverb) to create a new meaning: give up (to stop trying), look after (to take care of), put off (to postpone). Phrasal verbs are a grammatically distinct structure — they conjugate normally and can often be separated (put it off). An idiom is a broader category: it is any fixed expression with a non-literal meaning, which may include phrasal verbs but also covers longer multi-word expressions such as the tip of the iceberg, hit the nail on the head, or once in a blue moon. All phrasal verbs with non-literal meanings are idioms, but not all idioms are phrasal verbs.
There is no fixed official number, but research into CEFR vocabulary suggests that B2 learners benefit from knowing approximately 200–400 high-frequency idiomatic expressions — including common phrasal verbs. Cambridge B2 First examiners look for natural use of idiomatic language in the Writing and Speaking components. Rather than trying to memorise every idiom in the dictionary, focus on the most frequent ones in your target domain: general conversation, business, or academic English. Consistent reading of authentic English texts, watching films and TV without subtitles, and using idiom flash-card decks are all effective strategies for building idiomatic vocabulary at this level.
Some idioms are appropriate in formal and professional contexts, while others are purely informal. Idioms such as in the long run, on the other hand, a double-edged sword, and the tip of the iceberg are widely used in journalism, business reports, and even academic writing. By contrast, idioms such as kick the bucket, going bananas, or a piece of cake are informal and unsuitable for formal registers. In IELTS Writing Task 2, using very informal idioms in an academic essay will lower your Lexical Resource score. The key skill is matching the idiom to the appropriate register, which is why this quiz presents each idiom in a context sentence.
English idioms are often grouped by theme or source image. The most common categories include: body-part idioms (keep an eye on, get cold feet, bite your tongue), animal idioms (let the cat out of the bag, the elephant in the room, a wolf in sheep's clothing), weather idioms (under the weather, every cloud has a silver lining, brainstorm), colour idioms (out of the blue, green with envy, tickled pink), time idioms (once in a blue moon, in the nick of time, burn the midnight oil), and money and work idioms (cost an arm and a leg, cut corners, on the ball). Learning idioms by category makes them easier to remember because thematically related items share mental hooks.
Context is your most powerful tool. First, identify the grammatical role of the idiom — is it acting as a verb phrase, noun phrase, or adjective? Then look at the words around it for clues about the emotional tone (positive or negative) and the situation. For example, if someone says we really need to bite the bullet on this decision, the word need and the sense of obligation suggest the idiom means something difficult but necessary. Finally, consider the literal image — biting a bullet (something painful but done without flinching in old battlefield surgery) reinforces the meaning. This quiz deliberately presents idioms in context sentences precisely so you can practise this inference strategy.
Yes, there are notable differences. British English favours idioms such as Bob's your uncle (meaning everything is sorted), a dog's dinner (a mess), spend a penny (to use the toilet), and taking the mickey (teasing someone). American English has idioms such as ballpark figure (approximate estimate), touch base (make contact), take a rain check (decline an invitation but suggest a future time), and Monday morning quarterback (someone who criticises decisions after the fact). Many idioms are shared across varieties: bite the bullet, hit the nail on the head, and under the weather are understood everywhere. This quiz focuses on internationally recognised idioms used across both major varieties.
In IELTS Speaking, examiners award marks for Lexical Resource, which includes the accurate and natural use of idiomatic language. A candidate who appropriately uses expressions such as it goes without saying, in the long run, or on the fence demonstrates C1-level vocabulary range. In Writing Task 2, neutral and semi-formal idioms can enrich your expression when used correctly, though overuse or incorrect use will lower your score. This quiz strengthens your understanding of idiom meanings in context — the essential foundation for using them accurately under exam conditions. Combine it with the Flash Cards exercise to reinforce active recall before your exam date.
