Idioms and Phrases
An idiom is an established expression whose meaning is not fully predictable from its individual words. A phrase is a group of words used together; some phrases are idiomatic, while others mean exactly what their words suggest. Understanding an idiom means recognising the intended meaning of the complete expression.
For example, “The task was a piece of cake” means the task was very easy. The sentence is not about food. In contrast, “She ate a piece of cake” can use the same words literally, so the surrounding sentence matters.
The 50 expressions below are grouped by theme, with a simple meaning, a natural example and a short explanation. Begin with the familiar expressions, then study the less familiar ones through their situations. The solved examples and practice questions show how to use context to choose the right meaning.
Understanding idioms in a sentence
Read the entire sentence before deciding what an expression means. Ask what happened, how the people reacted and whether the ordinary literal meaning fits. Replace the idiom mentally with a plain-English meaning and check that the message remains sensible.
Learn the complete expression rather than replacing its words with synonyms. We say spill the beans, not spill the peas. However, tense and pronouns can change: spill the beans, spilled the beans and she has spilled the beans all retain the idiomatic meaning.
In an entry such as lose one's temper, one's stands for the appropriate possessive word: my, your, his, her, our or their. “He lost his temper” describes him becoming angry. The words did not reverse the statement: “He did not lose his temper” means he remained calm, although the idiom itself still means become angry.
Many idioms are conversational. Learn to recognise them in passages and questions, but do not force them into every formal sentence. The examples below illustrate a particular use; some expressions can also have literal uses or other established meanings.
Work, effort and progress
1. A piece of cake
Meaning: Something very easy to do.
Example: “After practising similar questions, Meera found the first task a piece of cake.”
Meera completed the task easily. The expression describes difficulty, not the amount of time or money involved.
2. Call it a day
Meaning: Stop working or end an activity for now.
Example: “We had checked every page, so we decided to call it a day.”
The group stopped after finishing its work. The expression can also be used when people decide they have done enough without completing everything.
3. Set the wheels in motion
Meaning: Start a process that leads to further action.
Example: “The approval set the wheels in motion for the new library.”
Approval began the steps needed to create the library; it did not mean the library was already complete.
4. Get the ball rolling
Meaning: Make a start so that an activity or discussion can develop.
Example: “Riya got the ball rolling by suggesting a topic for the presentation.”
Her suggestion helped the group begin. This expression overlaps in meaning with set the wheels in motion.
5. Go the extra mile
Meaning: Make more effort than is normally expected.
Example: “The tutor went the extra mile by preparing individual feedback for every student.”
The extra effort was the personal feedback. No additional travel is implied.
6. Burn the midnight oil
Meaning: Work or study late into the night.
Example: “Aman burned the midnight oil while preparing his final presentation.”
The expression refers to working late, not necessarily working throughout the entire night.
7. Learn the ropes
Meaning: Learn how a task, job or activity is done.
Example: “The new assistant spent her first week learning the ropes.”
She was learning the procedures and practical details of the job.
8. Cut corners
Meaning: Skip proper steps to save time, money or effort, often reducing quality.
Example: “The team refused to cut corners when checking the safety equipment.”
They would not omit necessary checks. This is different from finding a valid, efficient method.
9. Back to the drawing board
Meaning: Return to planning because an earlier idea or attempt did not work.
Example: “The prototype failed the test, so it was back to the drawing board.”
The team needed to rethink the design rather than continue with the failed version.
10. On the ball
Meaning: Alert, attentive and quick to understand or act.
Example: “The receptionist was on the ball and noticed the booking error immediately.”
She spotted the problem promptly because she was paying attention.
Conversation, truth and understanding
11. Break the ice
Meaning: Ease initial tension and help people feel comfortable together.
Example: “The host asked everyone a light-hearted question to break the ice.”
The question made the start of the meeting less awkward.
12. Spill the beans
Meaning: Reveal secret information.
Example: “Rohan spilled the beans about the surprise party before the guests arrived.”
He revealed something that was meant to remain secret. The disclosure can be accidental or deliberate.
13. Hold one's tongue
Meaning: Choose not to speak, especially when tempted to say something.
Example: “During the argument, Riya held her tongue instead of making an angry remark.”
She deliberately stayed silent. The expression does not mean that she had nothing to say.
14. Come clean
Meaning: Admit the truth about something previously hidden.
Example: “The student came clean about copying part of the assignment.”
The student acknowledged what had been concealed. This differs from revealing someone else’s secret.
15. Read the room
Meaning: Understand the mood and reactions of the people present.
Example: “Seeing that everyone was worried, the speaker read the room and avoided jokes.”
The speaker adjusted to the group’s mood. The expression is informal.
16. Beat around the bush
Meaning: Avoid discussing the main point directly.
Example: “Please stop beating around the bush and tell me why the plan changed.”
The listener wants a direct explanation instead of indirect remarks. Beat about the bush is also an established form.
17. Hit the nail on the head
Meaning: Identify or describe something exactly right.
Example: “You hit the nail on the head when you said the instructions were unclear.”
The comment accurately identified the problem.
18. On the same page
Meaning: Sharing an understanding or agreement about something.
Example: “Before starting, we checked that everyone was on the same page about the deadline.”
The group wanted a common understanding of when the work was due.
19. Let the cat out of the bag
Meaning: Reveal a secret, often unintentionally.
Example: “Her question about the cake let the cat out of the bag about the celebration.”
The question exposed the secret. This expression is close in meaning to spill the beans.
20. Get the wrong end of the stick
Meaning: Misunderstand a situation or what someone means.
Example: “I got the wrong end of the stick and thought the meeting had been cancelled.”
The speaker misunderstood the message. This expression is especially associated with British English.
Problems, pressure and setbacks
21. In hot water
Meaning: In trouble, often because of something one has done.
Example: “The employee was in hot water after sharing a confidential file.”
The disclosure caused trouble for the employee. Being busy or rushed is not the meaning.
22. Throw a spanner in the works
Meaning: Cause a problem that disrupts a plan or process.
Example: “A last-minute venue cancellation threw a spanner in the works.”
The cancellation interrupted the arrangements. This is a British expression; American English also uses throw a wrench in the works.
23. Weather the storm
Meaning: Survive or endure a difficult period.
Example: “The small shop weathered the storm of several months of poor sales.”
The shop managed to continue despite the difficulty. The expression does not mean that no harm or loss occurred.
24. A sword of Damocles
Meaning: A serious threat that hangs over someone and could bring harm.
Example: “The possibility of losing their only contract hung over the firm like a sword of Damocles.”
The unresolved threat created continuing insecurity. This is a more literary expression than most entries here.
25. The writing on the wall
Meaning: Clear warning signs that something bad is likely to happen.
Example: “When three major clients left, the owners saw the writing on the wall.”
The departures warned of future trouble. A warning sign is different from the threatened event itself.
26. Against the clock
Meaning: Working with very little time available before a deadline.
Example: “The volunteers worked against the clock to prepare the hall before the guests arrived.”
They faced time pressure and needed to finish quickly.
27. Have one's back to the wall
Meaning: Be in a difficult situation with few choices available.
Example: “With the deadline hours away and the main computer broken, the team had its back to the wall.”
The team had little room to manoeuvre. The expression emphasises pressure and limited options.
28. Between a rock and a hard place
Meaning: Faced with two difficult or unpleasant alternatives.
Example: “Accepting the order meant missing another deadline, but refusing it meant losing a client; we were between a rock and a hard place.”
Both available choices had a serious disadvantage.
29. Bite the bullet
Meaning: Accept and face an unpleasant or difficult action because it is necessary.
Example: “She bit the bullet and told the client that the delivery would be late.”
She faced an uncomfortable conversation instead of avoiding it.
30. Flog a dead horse
Meaning: Waste effort on a matter that cannot usefully be changed or pursued.
Example: “Arguing again over the permanently closed application was flogging a dead horse.”
Further effort would not change the outcome. Beat a dead horse is another established form, particularly in American English.
Feelings, behaviour and timing
31. On tenterhooks
Meaning: Anxious while waiting for an important event or outcome.
Example: “The candidates were on tenterhooks while waiting for the shortlist.”
Their anxiety came from not knowing the result. The spelling is tenterhooks, not tenderhooks.
32. Lose one's temper
Meaning: Become angry and lose control of how one expresses that anger.
Example: “He lost his temper and shouted when he discovered the missing file.”
The expression refers to anger, not simply any strong emotion.
33. Keep a low profile
Meaning: Avoid attracting attention.
Example: “The actor kept a low profile during the dispute.”
The actor stayed out of public attention. The expression does not itself explain whether the person was at fault.
34. Get a taste of one's own medicine
Meaning: Experience the same unpleasant treatment one previously gave others.
Example: “After repeatedly interrupting his teammates, he got a taste of his own medicine when they interrupted him.”
The same behaviour was directed back at him. General bad luck alone does not express this idea.
35. Hold your horses
Meaning: Wait, be patient or avoid acting too quickly.
Example: “Hold your horses; we have not checked the final price yet.”
The speaker asks someone to slow down before proceeding. This is an informal expression.
36. Get cold feet
Meaning: Become nervous and hesitate about doing something previously planned.
Example: “She got cold feet just before volunteering to speak on stage.”
Her nervousness made her hesitate about taking the planned action.
37. On cloud nine
Meaning: Extremely happy.
Example: “Riya was on cloud nine after receiving her first job offer.”
The expression describes strong happiness, not confusion or nervousness.
38. Under the weather
Meaning: Feeling unwell.
Example: “I am a little under the weather, so I will rest this evening.”
The speaker feels ill. No particular diagnosis or severity is specified.
39. Out of the blue
Meaning: Unexpectedly, without warning.
Example: “An old classmate called me out of the blue after five years.”
The call was a surprise. This expression concerns expectation rather than frequency.
40. Once in a blue moon
Meaning: Very rarely.
Example: “We visit that distant village once in a blue moon.”
The visits happen infrequently, not never. Unlike out of the blue, this expression describes frequency.
Choices, opportunities and money
41. The ball is in your court
Meaning: It is now your turn or responsibility to decide or act.
Example: “We have sent the revised offer; the ball is now in your court.”
The other person must respond or take the next step. The possessive can change: her court, their court or our court.
42. Sit on the fence
Meaning: Avoid choosing between opposing sides or options.
Example: “The committee asked him to stop sitting on the fence and state his preference.”
He had avoided committing himself. The expression does not tell us whether this was due to caution or indecision.
43. Jump the gun
Meaning: Act too early, before the right time or signal.
Example: “They jumped the gun by announcing the result before it was approved.”
The announcement was premature. Acting quickly is not necessarily jumping the gun unless the timing is too early.
44. A leap in the dark
Meaning: An action or decision taken without knowing what its result will be.
Example: “Starting a business in an unfamiliar field felt like a leap in the dark.”
The decision involved uncertainty about the outcome.
45. The last straw
Meaning: The final difficulty that makes an already bad situation intolerable.
Example: “After several missed deliveries, the damaged parcel was the last straw.”
The parcel was the final problem after earlier difficulties, not the only problem.
46. A silver lining
Meaning: A positive aspect of an otherwise unpleasant situation.
Example: “The cancelled trip had a silver lining: we could attend our cousin’s celebration.”
The cancellation remained disappointing, but it brought one benefit.
47. A blessing in disguise
Meaning: Something that first seems bad but later proves beneficial.
Example: “Missing that bus was a blessing in disguise because she met a future business partner while waiting.”
The apparent misfortune led to an unexpected benefit. The later outcome is essential to the meaning.
48. Put all your eggs in one basket
Meaning: Risk everything on a single plan, choice or opportunity.
Example: “She applied to several colleges instead of putting all her eggs in one basket.”
She avoided relying entirely on one admission decision.
49. Make ends meet
Meaning: Have enough money to cover necessary expenses.
Example: “He took an evening job to make ends meet while studying.”
The extra income helped cover basic costs. The expression does not mean becoming wealthy.
50. Cost an arm and a leg
Meaning: Be very expensive.
Example: “The emergency repairs cost an arm and a leg.”
The repairs required a large amount of money. This is an informal exaggeration, not a literal injury.
Solved examples: use the situation to choose the meaning
Case 1: Separate an idiom from a literal action
Example: “The host told a funny story to break the ice.” What does the highlighted expression mean?
A. Damage something frozen
B. Make people feel comfortable at the beginning
C. End the meeting
D. Start an argument
The setting is a social gathering, and the host uses a story to help people relax. The answer is B. Replacing the expression gives “The host told a funny story to make people feel comfortable at the beginning,” which preserves the message. A follows the literal image but does not fit this situation.
Case 2: Distinguish meaning from the effect of a negative
Example: “Despite the delay, the supervisor did not lose his temper.” What does the sentence tell us?
A. He became angry
B. He forgot the reason for the delay
C. He remained calm
D. He stopped working
Lose his temper means become angry, but the sentence says did not. Therefore, C describes the supervisor's response. If the question asked only for the meaning of lose one's temper, “become angry” would be correct. Read exactly what is being asked.
Case 3: Find the clue that separates related expressions
Example: “The supplier's sudden closure threw a spanner in the works, forcing us to change the launch date.” Choose the meaning.
A. Started a process
B. Disrupted the plan
C. Ended a disagreement
D. Made the task easy
The changed launch date shows that the closure interfered with the arrangements. The answer is B. Set the wheels in motion would mean starting a process, but the highlighted expression describes an obstacle to an existing plan.
Case 4: Identify a warning rather than an outcome
Example: “Repeated losses were the writing on the wall for the shop.” Choose the meaning.
A. A guarantee of recovery
B. A list of completed tasks
C. A clear warning of future trouble
D. A decision to stop work for the day
Repeated losses suggest that the shop may face serious trouble. Choose C. The expression points to warning signs; it does not necessarily mean the shop has already closed. This distinction prevents an answer from claiming more than the sentence says.

Answer key
1. B: Very easy. A piece of cake describes an easy task. The designer's experience supports this meaning; the expression does not describe cost or timing.
2. A: Understand the mood of those present. Read the room means notice the group's feelings and reactions. The tense setting explains why the speaker should consider whether a joke is appropriate.
3. C: Waiting anxiously. On tenterhooks combines anticipation with nervousness. Waiting for results provides the relevant context.
4. D: Survived the difficult period. Weathered the storm means endured the trouble. It does not guarantee that the company suffered no losses.
5. A: Admitted the hidden truth. Came clean refers to revealing the truth about something concealed. Here it is an admission about altering figures.
6. C: Call it a day. This means stop the activity for now. The completed checks explain why the group is ready to stop.
7. B: Got a taste of his own medicine. He experienced the same unpleasant behaviour he had previously shown others. The matching treatment is what makes this expression appropriate.
8. D: Flogging a dead horse. The decision cannot change, so further argument would be pointless. Merely finding a task difficult would not be enough to justify this idiom.
9. A: A continuing serious threat. A sword of Damocles describes a danger hanging over someone. The possible loss of the contract creates that insecurity.
10. C: It is your turn to respond or act. The sender has taken a step and is waiting for the recipient. The idiom does not specify whether the recipient must accept or reject the offer.
11. B: Chose to remain silent. Held her tongue describes restraint despite wanting to speak. It does not mean she changed the subject aloud.
12. D: Very infrequent visits. Once in a blue moon describes rarity. It does not specify the time of day or whether each visit is surprising.
13. A: Unexpectedly. Out of the blue describes a lack of warning. It is different from once in a blue moon, which describes frequency.
14. C: The final problem that made the situation intolerable. The last straw follows earlier difficulties. The sentence explicitly mentions those earlier problems.
15. B: Riya kept her anger under control. The words did not negate lose her temper. The whole statement describes restraint, although the idiom without the negative means become angry and lose control.
Common mistakes to avoid
Taking every expression literally. A person can spill actual beans, but a sentence about a secret party usually uses spill the beans idiomatically. Decide from the context rather than assuming either use in advance.
Confusing similar expressions. Out of the blue means unexpectedly; once in a blue moon means rarely. Come clean stresses admitting hidden truth, while spill the beans stresses revealing secret information. Similar situations do not make every expression interchangeable.
Changing the fixed words. Keep established wording such as on tenterhooks and the writing on the wall. Change tense and pronouns when needed, but do not invent synonyms inside a fixed idiom.
Ignoring a negative. “He did not lose his temper” is different from “He lost his temper.” Check whether the task asks for the idiom's meaning or the meaning of the complete statement.
Adding more than the idiom says. Weather the storm does not promise an easy recovery. Keep a low profile does not prove guilt. Select a meaning that stays within what the expression communicates.
FAQs
Do I need detailed grammar lessons to learn idioms?
Not for this list. You mainly need to understand the situation and the expression's established meaning. Basic tense and pronoun changes help you use an idiom naturally, such as changing hold one's tongue to she held her tongue.
Should I memorise only the meaning?
Learn one example with each meaning. An example shows the situation, the form of the expression and how it connects to the sentence. Then write your own sentence and check that the same meaning fits.
Can two idioms have similar meanings?
Yes. Spill the beans and let the cat out of the bag both concern revealing a secret. A question should provide enough context or sufficiently different options to make its intended answer clear.
Are all idioms suitable for formal writing?
No. Many are conversational, while a few, such as a sword of Damocles, are more literary. Recognise their meanings, but use plain wording when an idiom would make a formal message less clear.
How can I revise these 50 expressions?
Study one theme at a time. Cover the meanings, read each example and explain the idiom in your own words. Revisit expressions you confuse, especially pairs that differ in frequency, expectation or the type of action they describe.
