Many learners search for idioms for IELTS because they want a higher band score in the IELTS Speaking test. IELTS idioms with examples show how idiomatic language works in real conversation. For instance, break a leg means good luck, so its literal meaning does not apply. These special meanings are part of figurative language, and they help you sound more natural like native speakers.
However, IELTS examiners do not reward memorised idioms or forced memorisation. They check appropriate and accurate use under the Lexical Resource criteria, so a wider vocabulary range matters more. Therefore, this guide lists common idioms with clear meanings and natural examples for IELTS preparation. Use them in Part 1, Part 2, and Part 3 when the context fit feels right.
What Is an Idiom?
An idiom is a fixed or established expression whose figurative meaning is different from the literal meaning of its individual words.
For example, “break the ice” does not normally mean physically breaking ice. It means to make people feel more comfortable when they first meet. Similarly, “spill the beans” does not mean dropping beans; it means revealing a secret.
Idioms can be confusing for English learners because the words often don’t give you enough information to work out the real meaning. You usually need to learn the expression as a whole and understand the context in which people use it.
For IELTS learners, this distinction matters. An expression may sound impressive, but if you use it incorrectly, it can make your answer less natural rather than more fluent.
How Is an Idiom Different From a Metaphor or Simile?
These forms of figurative language are related, but they are not interchangeable.
| Type | What it does | Example |
| Idiom | An established expression with a figurative meaning | “I need to hit the books.” |
| Metaphor | Directly describes one thing as another for comparison | “The exam was a mountain to climb.” |
| Simile | Compares two things using “like” or “as” | “The exam felt like a marathon.” |
| Literal expression | Uses words in their ordinary, direct meaning | “I studied for three hours.” |
The important point is that not every creative phrase is an idiom. “The exam was a mountain” can be a creative metaphor, but it is not automatically a traditional English idiom.
Established idioms are expressions that English speakers recognize as having a conventional figurative meaning. That makes them different from expressions a speaker invents spontaneously.
Why Use Idioms for IELTS?
Idioms can help IELTS learners express ideas with more personality and precision, especially during the Speaking test. The official IELTS Speaking criteria assess lexical resource, including the appropriate use of vocabulary, style, collocation, and idiomatic expressions.
Used naturally, idioms can help you:
- Express emotions without using the same basic adjectives repeatedly.
- Make a personal story more vivid and memorable.
- Describe difficult experiences in a conversational way.
- Show that you understand common everyday English.
- Add personality to answers about study, work, hobbies, pressure, success, or challenges.
- Demonstrate flexibility in vocabulary.
However, idioms aren’t magic phrases that automatically improve an IELTS answer. IELTS specifically emphasizes appropriate and accurate language, and official guidance warns candidates not to overuse idioms or force expressions that don’t fit the topic.
For academic IELTS Writing, be particularly careful. Many idioms are conversational and can sound too informal in an essay. A clear academic expression is often better than a colorful idiom.

Hit the Books
Meaning: “Hit the books” means to start studying seriously, especially when you have a lot of work to do.
The expression is not literal. You aren’t hitting books. The “hitting” suggests getting down to the task with energy and purpose.
In a Sentence:
“I’ve got my IELTS test next month, so I’m going to hit the books every evening after work.”
Other Ways to Say It:
- Start studying
- Get down to studying
- Study hard
- Hit the textbooks — slightly more specific
Explanation:
This is one of the most useful informal expressions for talking about exam preparation. It creates a simple image of someone getting straight to their study materials instead of wasting time.
It works particularly well when discussing your study routine, preparation, or academic goals.
Tone: Casual and conversational.
Best Use:
IELTS Speaking, everyday conversation, informal messages, and storytelling. It is generally too informal for a formal academic essay.
Common Mistake:
Don’t use it as a literal synonym for “read.” If you’re simply reading a novel for pleasure, “hit the books” may sound unnatural because the expression normally suggests purposeful study.
Burn the Midnight Oil
Meaning: “Burn the midnight oil” means to work or study late into the night.
The literal image refers to working late by the light of an oil lamp. Today, the expression is figurative.
In a Sentence:
“I had to burn the midnight oil for a few nights before my IELTS Speaking test because I wanted to feel fully prepared.”
Other Ways to Say It:
- Stay up late studying
- Work late into the night
- Study late
- Work through the night — stronger and more extreme
Explanation:
This idiom highlights long hours and late-night effort. It can describe studying, working, writing, or completing an important task.
It is useful when telling a story about a demanding period of preparation.
Tone: Informal, slightly literary, and familiar.
Best Use:
Speaking answers about education, work, deadlines, preparation, or a challenging project.
Common Mistake:
The idiom refers specifically to staying up late to work or study. It isn’t the best choice when someone simply studies hard during the daytime.
Learn by Heart
Meaning: “Learn by heart” means to memorize something so well that you can remember it without looking at it.
In a Sentence:
“I learned several useful phrases by heart, but I made sure I understood how to use them instead of simply repeating them.”
Other Ways to Say It:
- Memorize
- Commit to memory
- Know from memory
- Memorize word for word — stronger and more specific
Explanation:
This expression is useful when discussing vocabulary, speeches, poems, facts, or information that someone has memorized.
For IELTS preparation, it also introduces an important warning: memorizing complete answers is different from learning useful language. A memorized response can sound unnatural if it doesn’t match the question.
Tone: Neutral and common.
Best Use:
Speaking, everyday conversation, education-related topics, and personal experiences.
Common Mistake:
“Learn by heart” means memorize, not simply “understand.” You can understand an idea without knowing it by heart.
Brush Up on Something
Meaning: “Brush up on something” means to review and improve a skill or area of knowledge that you already know.
In a Sentence:
“I need to brush up on my pronunciation before I take the IELTS test.”
Other Ways to Say It:
- Review
- Refresh your knowledge of
- Improve your skills in
- Practise again
Explanation:
This idiom is especially useful because IELTS candidates often prepare by revisiting knowledge they already have rather than learning everything from the beginning.
The image is of gently cleaning or polishing something until it becomes better again. In modern English, the expression commonly refers to refreshing an existing skill.
Tone: Informal and natural.
Best Use:
IELTS Speaking, conversations about study or work, language learning, and personal development.
Common Mistake:
Use “brush up on” when you already have some knowledge. If you are learning a subject for the first time, “learn” or “study” is more accurate.
Get the Hang of Something
Meaning: “Get the hang of something” means to learn how to do something or understand how it works.
In a Sentence:
“At first, I struggled to organize my Speaking answers, but after a few practice sessions, I got the hang of it.”
Other Ways to Say It:
- Learn how to do it
- Get used to it
- Figure it out
- Become familiar with it
Explanation:
This expression is useful when describing progress. It suggests that something was difficult or unfamiliar at first but gradually became easier.
That makes it particularly suitable for IELTS answers about learning a skill, overcoming a difficulty, or adapting to a new situation.
Tone: Casual and conversational.
Best Use:
Speaking and informal writing.
Common Mistake:
Don’t use it when you mean “master completely.” Getting the hang of something means reaching a basic or workable understanding, not necessarily becoming an expert.
Put Your Mind to Something
Meaning: “Put your mind to something” means to give something serious attention, determination, and effort.
In a Sentence:
“If I put my mind to improving my vocabulary, I know I can make steady progress.”
Other Ways to Say It:
- Concentrate on something
- Commit yourself to something
- Focus on something
- Apply yourself
Explanation:
This expression emphasizes determination rather than simple attention. It suggests that success becomes more achievable when someone seriously commits to a goal.
It can fit naturally into IELTS answers about ambitions, education, personal development, or overcoming challenges.
Tone: Encouraging and conversational.
Best Use:
IELTS Speaking, motivational conversations, personal messages, and informal writing.
Common Mistake:
“Put your mind to” normally takes a task, goal, or activity. “I put my mind to happy” is incorrect because happiness is not normally treated as the task in this construction.
Go the Extra Mile
Meaning: “Go the extra mile” means to make more effort than is normally expected.
In a Sentence:
“My English teacher went the extra mile by giving me detailed feedback on my practice answers.”
Other Ways to Say It:
- Make an extra effort
- Do more than expected
- Put in extra effort
- Make a special effort
Explanation:
The image comes from traveling farther than necessary. Figuratively, it describes someone who doesn’t stop at the minimum requirement.
This is useful for IELTS topics involving teachers, education, customer service, work, relationships, or personal achievement.
Tone: Positive and widely understood.
Best Use:
Speaking, informal writing, personal stories, and workplace conversations.
Common Mistake:
Don’t use it simply to mean “work hard.” The expression usually carries the additional idea of doing more than what was expected.
Keep Your Eye on the Ball
Meaning: “Keep your eye on the ball” means to stay focused on what is important and avoid distractions.
In a Sentence:
“With only two weeks left before the exam, I need to keep my eye on the ball and follow my study plan.”
Other Ways to Say It:
- Stay focused
- Keep your focus
- Concentrate on the goal
- Don’t lose sight of the objective
Explanation:
The expression comes from sports, where players need to watch the ball carefully. In everyday English, it describes mental focus.
For IELTS preparation, it works well when talking about goals, distractions, deadlines, or staying motivated.
Tone: Informal and motivational.
Best Use:
Speaking, advice, coaching, workplace communication, and personal development.
Common Mistake:
The “ball” is usually metaphorical. You don’t need to be discussing sports to use this expression.
On the Right Track
Meaning: “On the right track” means making progress in the correct direction.
In a Sentence:
“My teacher said that my practice answers were on the right track, although I still needed to improve my pronunciation.”
Other Ways to Say It:
- Heading in the right direction
- Making good progress
- Moving toward the right goal
- Doing the right thing
Explanation:
This expression uses the image of traveling along a track. If you’re on the right track, you’re moving toward the desired result.
It’s especially useful when describing progress without claiming that the final goal has already been achieved.
Tone: Neutral and common.
Best Use:
IELTS Speaking, education, work, personal goals, and feedback.
Common Mistake:
Being “on the right track” does not necessarily mean you have succeeded. It means your approach or direction appears appropriate.
Learn the Ropes
Meaning: “Learn the ropes” means to learn how a particular activity, job, or situation works.
In a Sentence:
“When I first joined the language course, I needed a few weeks to learn the ropes.”
Other Ways to Say It:
- Learn how things work
- Get familiar with the process
- Learn the basics
- Find your feet — similar but not identical
Explanation:
This idiom is often connected with learning the practical details of a new environment. The phrase is traditionally associated with learning the ropes on a sailing ship.
For IELTS, it can describe starting a new course, adapting to a new school, beginning a job, or becoming familiar with a new routine.
Tone: Informal and established.
Best Use:
Speaking and informal conversation.
Common Mistake:
It normally refers to learning the practical workings of something, not memorizing academic information.
Make the Grade
Meaning: “Make the grade” means to reach the required standard or level.
In a Sentence:
“I wasn’t sure whether my first practice test would make the grade, so I spent another month working on my weak areas.”
Other Ways to Say It:
- Meet the standard
- Reach the required level
- Qualify
- Be good enough
Explanation:
This idiom focuses on meeting a requirement or standard. It can therefore fit naturally into discussions about exams, qualifications, employment, education, and personal goals.
Unlike “pass with flying colors,” it doesn’t necessarily suggest outstanding performance. It simply means the required standard has been reached.
Tone: Informal and fairly common.
Best Use:
Speaking about exams, qualifications, school, work, or achievement.
Common Mistake:
Don’t assume “make the grade” always means getting an excellent result. It generally means meeting the necessary standard.
Pass With Flying Colors
Meaning: “Pass with flying colors” means to succeed very well in a test, challenge, or difficult task.
In a Sentence:
“She was nervous about the interview, but she passed with flying colors.”
Other Ways to Say It:
- Pass with excellent results
- Succeed brilliantly
- Do extremely well
- Excel
Explanation:
This is a particularly natural expression when discussing successful performance. It gives the idea of coming through a challenge with a clearly positive result.
Although “pass” makes it especially suitable for exams, the expression can also be used more broadly for successfully completing a challenge.
Tone: Positive, informal, and familiar.
Best Use:
Speaking, personal stories, congratulations, and informal writing.
Common Mistake:
“Pass with flying colors” suggests strong success, not merely passing. If someone barely meets the minimum requirement, another expression would be more accurate.
Rise to the Occasion
Meaning: “Rise to the occasion” means to perform well when a difficult or important situation requires you to do your best.
In a Sentence:
“I was extremely nervous before my Speaking test, but I managed to rise to the occasion.”
Other Ways to Say It:
- Meet the challenge
- Perform well under pressure
- Step up
- Handle the situation successfully
Explanation:
This expression is about responding positively when circumstances demand extra effort or confidence.
It is useful for IELTS because candidates can naturally use it when discussing exams, public speaking, competitions, interviews, difficult decisions, or unexpected challenges.
Tone: Positive, slightly formal, and expressive.
Best Use:
Speaking, storytelling, speeches, and reflective writing.
Common Mistake:
The expression generally describes a successful response to a particular situation. It isn’t simply another way to say “be successful” in every context.

Bite the Bullet
Meaning: “Bite the bullet” means to accept something difficult or unpleasant and deal with it bravely.
In a Sentence:
“I was worried about taking the Speaking test, but eventually I decided to bite the bullet and book my exam.”
Other Ways to Say It:
- Face the challenge
- Do something difficult
- Get it over with
- Face the music — similar in some situations, but often emphasizes accepting the consequences of one’s actions
Explanation:
The expression creates a vivid image of someone enduring pain by biting down on a bullet. Today, it is normally used figuratively for facing something unpleasant that cannot be avoided.
It works well in personal stories where a learner describes overcoming fear, procrastination, or an uncomfortable challenge.
Tone: Informal and slightly dramatic.
Best Use:
Speaking, storytelling, casual conversation, and personal messages.
Common Mistake:
“Bite the bullet” doesn’t necessarily mean “enjoy the challenge.” It suggests that the situation is unpleasant, difficult, or intimidating.
Back to the Drawing Board
Meaning: “Back to the drawing board” means to start planning again because the previous attempt or plan did not work.
In a Sentence:
“My first study schedule was unrealistic, so I went back to the drawing board and created a simpler one.”
Other Ways to Say It:
- Start again
- Rethink the plan
- Try a different approach
- Redesign the strategy
Explanation:
The expression creates the image of an engineer or designer returning to a drawing board to develop a new plan.
For IELTS learners, it is particularly useful when discussing failed study methods, disappointing practice results, or changes to a preparation strategy.
Tone: Informal and widely understood.
Best Use:
Speaking, work-related conversations, problem-solving, and storytelling.
Common Mistake:
It usually implies that the previous plan needs substantial revision. For a small adjustment, “make a few changes” may be more accurate.
Go Back to Square One
Meaning: “Go back to square one” means to return to the beginning because your previous progress or approach has not produced the desired result.
In a Sentence:
“After realizing that I had been practising the wrong type of questions, I felt as if I had to go back to square one.”
Other Ways to Say It:
- Start again
- Return to the beginning
- Start from scratch

The expression is useful when a person loses progress or discovers that an approach isn’t working.
It can describe an IELTS learner who changes study methods, restarts a learning plan, or realizes that a basic skill needs more attention.
Tone: Informal and conversational.
Best Use:
Speaking and informal writing.
Common Mistake:
“Back to the drawing board” and “back to square one” are similar but not identical. The first focuses on replanning; the second emphasizes returning to the beginning.
In the Same Boat
Meaning: “In the same boat” means to be in the same difficult or challenging situation as someone else.
In a Sentence:
“Most of my classmates were in the same boat because we were all struggling with the amount of vocabulary we had to learn.”
Other Ways to Say It:
- In the same situation
- Facing the same problem
- In a similar position
- Going through the same thing
Explanation:
The boat represents a shared situation. If several people are in the same boat, they are dealing with similar circumstances.
This is useful for IELTS Speaking because it can help you connect your experience with other people’s experiences when discussing students, workplaces, communities, or social problems.
Tone: Informal and friendly.
Best Use:
Everyday conversation, IELTS Speaking, personal stories, and informal writing.
Common Mistake:
It doesn’t necessarily mean people agree with one another. They simply share a situation or problem.
A Piece of Cake
Meaning: “A piece of cake” means something that is very easy to do.
In a Sentence:
“The first few vocabulary exercises were a piece of cake, but the advanced ones were much more challenging.”
Other Ways to Say It:
- Very easy
- Easy as pie
- A breeze
- No problem
Explanation:
The idiom compares an easy task with something pleasant and effortless to consume.
It can make an IELTS Speaking answer sound relaxed and natural when you’re describing something that required little effort.
Tone: Casual, playful, and common.
Best Use:
Everyday conversation and IELTS Speaking.
Common Mistake:
Don’t use it to describe a difficult task ironically unless the context clearly makes the joke obvious. In a test, straightforward language is safer if the meaning could be misunderstood.
Not Rocket Science
Meaning: “Not rocket science” means something is not especially difficult to understand or do.
In a Sentence:
“Learning how to structure a basic response isn’t rocket science, but it does take regular practice.”
Other Ways to Say It:
- Not very difficult
- Quite straightforward
- Easy enough to understand
- Not complicated
Explanation:
The expression contrasts an ordinary task with rocket science, which is popularly associated with advanced technical knowledge.
It can be useful when discussing study techniques, everyday skills, or tasks that initially appear more complicated than they really are.
Tone: Informal and sometimes humorous.
Best Use:
IELTS Speaking and casual conversation.
Common Mistake:
It can sound dismissive if you’re talking about something that another person finds genuinely difficult. Use it carefully when discussing other people’s abilities.
Call It a Day
Meaning: “Call it a day” means to stop working on something for the day, usually because you’ve done enough or need a break.
In a Sentence:
“After three hours of practice, I decided to call it a day and continue tomorrow.”
Other Ways to Say It:
- Stop for today
- Finish work for the day
- Take a break
- Wrap things up — broader and not necessarily limited to a day
Explanation:
This expression is useful for talking about study routines and maintaining a sensible balance. It suggests that you are deliberately stopping rather than simply giving up.
For an IELTS learner, it can also support a natural answer about study habits, productivity, rest, or time management.
Tone: Casual and common.
Best Use:
Everyday conversation, IELTS Speaking, workplace communication, and informal writing.
Common Mistake:
“Call it a day” normally means stopping for the current day, not abandoning the task permanently.
