Finding natural idioms for good luck can make everyday English sound warmer and more expressive. These good luck idioms use figurative expressions and English phrases to share good fortune in memorable ways.
For example, break a leg is a common informal idiom used to wish someone good luck before a performance. However, English offers many alternative expressions for friends, family members, colleagues, and others facing an opportunity or challenge. This guide explains their idiom meanings, natural examples, and usage notes, helping you choose the right luck expressions for each situation.
What Is an Idiom?
An idiom is a fixed expression whose overall meaning cannot always be understood by simply adding together the literal meanings of its individual words.
For example, “spill the beans” does not literally mean dropping beans. It means to reveal a secret. Likewise, “break a leg” has a figurative meaning of wishing someone good luck rather than causing an injury.
Idioms can be confusing for English learners because their literal wording may create a completely different mental picture from their actual meaning. Learning the expression as a whole, along with its usual context, makes it easier to understand and use naturally.
How Is an Idiom Different From a Metaphor or Simile?
These forms of language can all make English more vivid, but they are not interchangeable.
| Type | What it does | Example |
| Idiom | Uses an established expression with a figurative meaning | “Break a leg.” |
| Metaphor | Describes one thing as another for comparison | “Her performance was a storm.” |
| Simile | Makes a comparison using “like” or “as” | “He ran like the wind.” |
| Literal expression | Means exactly what the words say | “She wished him good luck.” |
The key difference is that an idiom is an established expression with a conventional meaning. A writer can create a new metaphor at any time, but that does not automatically make it an idiom.
For instance, “His success was a shooting star” can work as a creative metaphor. It is not necessarily an established English idiom. This distinction matters when learning vocabulary because memorizing an invented phrase as a traditional idiom can lead to unnatural English.
Why Use Idioms for Good Luck?
Idioms let you talk about good luck, hope, chance, and success with more personality.
Instead of simply saying “I hope it goes well,” you might say, “Fingers crossed!” When someone has unexpectedly found a great opportunity, “They really landed on their feet” may capture the situation better than a plain statement about luck.
These expressions can help you:
- Express encouragement before an important event.
- Show hope when the outcome is uncertain.
- Describe an unexpected fortunate opportunity.
- Add personality to everyday conversations.
- Make stories and creative writing more vivid.
- Understand common English expressions more easily.
- Recognize the difference between chance, skill, and success.
- Adjust your language to suit casual, humorous, literary, or professional situations.
Not every expression below is used to directly wish someone luck. Some describe having luck, losing luck, relying on chance, or benefiting from a fortunate situation. That wider range makes the vocabulary more useful.

Break a Leg
Meaning:
“Break a leg” is an informal idiom used to wish someone good luck, particularly before a performance. Its literal wording sounds negative, but its conventional meaning is positive. Cambridge Dictionary specifically identifies it as an expression used to wish someone good luck, especially before a performance.
In a Sentence:
“You’re going on stage in ten minutes—break a leg!”
Other Ways to Say It:
- Best of luck
- Good luck
- Give it your best
- You’ve got this
Explanation:
The expression creates a deliberately strange image: instead of directly saying “good luck,” the speaker says something that sounds like the opposite. It is especially associated with theater and performance, although people sometimes use it jokingly before other important events.
Tone: Casual, playful, encouraging.
Best Use:
Use it before a play, concert, audition, speech, presentation, or similar performance. Avoid it when the situation is already serious or physically dangerous, where the wording could sound insensitive.
Cross Your Fingers
Meaning:
“Cross your fingers” means to hope strongly that something will happen the way you want. It is commonly used when the result is uncertain.
In a Sentence:
“I’ve sent the application, so cross your fingers that I get an interview.”
Other Ways to Say It:
- Hope for the best
- Keep your fingers crossed
- Wish me luck
- Let’s hope it works out
Explanation:
The image comes from the familiar gesture of crossing two fingers as a symbolic way of hoping for a favorable result. Unlike “break a leg,” this expression can fit many ordinary situations, from waiting for exam results to hoping for good weather.
Tone: Casual and hopeful.
Best Use:
Everyday conversation, texts, personal messages, and informal writing.
Common Mistake:
Learners sometimes use an unnatural construction such as “I cross my fingers for you.” “I have my fingers crossed” or “Cross your fingers” is more natural in common usage.
Knock on Wood
Meaning:
“Knock on wood” is an informal American idiom used to avoid tempting bad luck after mentioning something fortunate or expressing hope about the future. In British English, “touch wood” is the usual equivalent.
In a Sentence:
“I haven’t had any problems with the car this year, knock on wood.”
Other Ways to Say It:
- Touch wood
- Let’s hope it stays that way
- Fingers crossed
- Hopefully nothing goes wrong
Explanation:
The expression reflects a superstition about touching or knocking on wood to protect good fortune. You may hear someone say the words while actually tapping a wooden surface, although the physical action is not required.
Tone: Informal, conversational, lightly superstitious.
Best Use:
Everyday conversation, friendly messages, and informal storytelling.
Common Mistake:
The established expression is “knock on wood,” not “knock the wood.” In British English, “touch wood” is especially common.
With Any Luck
Meaning:
“With any luck” expresses hope that a desired event or result will happen. Cambridge Dictionary classifies it as an informal idiom and also records “with a little luck” and the British “with a bit of luck.”
In a Sentence:
“With any luck, we’ll finish the project before the deadline.”
Other Ways to Say It:
- Hopefully
- If things go well
- With a little luck
- If all goes well
Explanation:
This expression is useful because it does not promise success. It leaves room for uncertainty while showing optimism. That makes it more natural than a strong statement that something definitely will happen.
Tone: Casual and optimistic.
Best Use:
Everyday conversation, emails, storytelling, and informal professional communication.
As Luck Would Have It
Meaning:
“As luck would have it” means by chance, often introducing a coincidence that turns out to be helpful or relevant.
In a Sentence:
“As luck would have it, the person sitting next to me knew exactly how to fix the printer.”
Other Ways to Say It:
- By chance
- As it happened
- Fortunately
- As it turned out
Explanation:
This expression gives a story a sense of coincidence. It often appears when an unexpected event happens at exactly the right—or sometimes wrong—moment.
It does not always guarantee a positive outcome. Context determines whether the coincidence is fortunate or unfortunate.
Tone: Conversational, narrative, slightly literary.
Best Use:
Storytelling, essays, articles, and conversations about unexpected events.
Be in Luck
Meaning:
To “be in luck” means to be in a surprisingly good situation, particularly because something you want is available or possible.
In a Sentence:
“You’re in luck—we just received two more tickets.”
Other Ways to Say It:
- You’re fortunate
- You got lucky
- Things worked out
- You’re in a good position
Explanation:
This idiom is especially useful when someone discovers that circumstances have unexpectedly gone in their favor. It often appears in short replies because it quickly communicates a pleasant surprise.
Tone: Friendly and conversational.
Best Use:
Everyday speech, customer interactions, casual writing, and friendly messages.
Common Mistake:
“Be in luck” is not simply another way to say “be happy.” It specifically points to a favorable opportunity or situation.
Your Luck’s In!
Meaning:
“Your luck’s in!” is a humorous British idiom used to tell someone that they are lucky or successful, often because something desirable appears to be available to them.
In a Sentence:
“Your luck’s in—the last table at the restaurant has just become available.”
Other Ways to Say It:
- You’re in luck
- You got lucky
- Fortune is on your side
- Things are going your way
Explanation:
This expression has a distinctly conversational British flavor. The apostrophe in luck’s represents “luck is.” It can also have a teasing or playful tone depending on the situation.
Tone: British, humorous, informal.
Best Use:
Casual conversation, friendly banter, and light storytelling.
The Luck of the Draw
Meaning:
“The luck of the draw” describes a result determined by chance when you have little or no control over the outcome.
In a Sentence:
“We were assigned our seats randomly, so getting the front row was just the luck of the draw.”
Other Ways to Say It:
- Pure chance
- Random selection
- The way things turned out
- Chance alone
Explanation:
The expression comes from the idea of drawing something randomly, such as a card or ticket. It is useful when luck rather than ability, preparation, or choice explains the result.
Tone: Neutral and conversational.
Best Use:
Everyday conversation, discussions of competitions, workplace situations, and explanations involving random outcomes.
Common Mistake:
Do not use it when someone deliberately creates an outcome through skill or careful planning. The central idea is lack of control over the result.
More by Luck Than Judgment
Meaning:
The British idiom “more by luck than judgment” means something succeeded because of chance rather than special skill or careful decision-making.
In a Sentence:
“I managed to guess the right answer, but it was more by luck than judgment.”
Other Ways to Say It:
- More by chance than skill
- Mostly luck
- A lucky guess
- By accident rather than design
Explanation:
This expression is often used modestly or humorously. Someone may have achieved an impressive result but admit that luck played a larger role than expertise.
It is especially useful when you want to separate good fortune from genuine ability.
Tone: British, conversational, modest, sometimes humorous.
Best Use:
Everyday conversation, storytelling, sports discussions, and informal writing.
In the Cards
Meaning:
“In the cards” means likely to happen. In British English, “on the cards” is also common.
In a Sentence:
“With the team’s recent progress, another successful season may be in the cards.”
Other Ways to Say It:
- Likely
- Possible
- On the horizon
- Looking possible
Explanation:
The image comes from cards used for games or fortune-telling, although the modern idiom simply means that something appears likely to happen. It can refer to positive, negative, or neutral events.
Tone: Conversational and figurative.
Best Use:
Predictions, discussions about future possibilities, storytelling, and informal writing.
Common Mistake:
“In the cards” does not mean that something is guaranteed. It expresses possibility or likelihood rather than certainty.
Fortune Smiles on Someone
Meaning:
When “fortune smiles on someone,” that person is lucky and good things happen to them.
In a Sentence:
“Fortune smiled on Maya when an unexpected scholarship covered her remaining tuition.”
Other Ways to Say It:
- Luck was on her side
- She was fortunate
- Things went her way
- She had good fortune
Explanation:
This is a more personified way of describing luck. Fortune is imagined as something capable of smiling upon a person, creating a warm image of favorable circumstances.
Tone: Literary, positive, slightly dramatic.
Best Use:
Creative writing, storytelling, speeches, and polished prose.
Context Note:
This expression can sound more literary than ordinary phrases such as “She got lucky,” so it may feel unusual in very casual conversation.
The Rub of the Green
Meaning:
“The rub of the green” is a British idiom referring to the luck someone experiences in a particular situation, especially a competition.
In a Sentence:
“They played brilliantly, but they didn’t get the rub of the green when two shots bounced badly.”
Other Ways to Say It:
- A stroke of luck
- The way the luck falls
- Fortune on the day
- The breaks going your way
Explanation:
The expression is strongly associated with British English and sporting contexts. It describes those small unpredictable events that can influence an outcome even when people have prepared carefully.
Tone: British, idiomatic, sporting, somewhat traditional.
Best Use:
Sports writing, sports conversations, and discussions about chance affecting results.
Common Mistake:
It is not a general synonym for “good luck” in every situation. It usually concerns how chance affects a particular outcome, especially in competition.
Push Your Luck
Meaning:
“Push your luck” means to try too hard to get an additional benefit and risk losing what you have already achieved.
In a Sentence:
“They’ve already given us an extra day, so I think we’d be pushing our luck by asking for another week.”
Other Ways to Say It:
- Take too much of an advantage
- Risk your good fortune
- Go too far
- Ask for too much
Explanation:
This idiom shows that luck can be treated almost like a limited resource. Someone who keeps demanding more after already receiving a favorable outcome may eventually lose that goodwill.
Tone: Informal, cautionary.
Best Use:
Everyday conversation, workplace discussions, friendly advice, and informal writing.
Common Mistake:
“Push your luck” is usually not praise. It warns that someone may be taking an unnecessary risk with a favorable situation.
Out of Luck
Meaning:
If someone is “out of luck,” they do not have the success or opportunity they wanted.
In a Sentence:
“If you wanted a window seat, you’re out of luck—the flight is completely booked.”
Other Ways to Say It:
- Unlucky
- No luck
- You’ve missed your chance
- It didn’t work out
Explanation:
This idiom is useful because it can describe a small disappointment without sounding overly dramatic. It often appears when an opportunity is unavailable or circumstances do not favor someone.
Tone: Casual and direct.
Best Use:
Everyday conversation, customer service, travel situations, and informal messages.
Context Note:
“Out of luck” does not necessarily suggest serious misfortune. It can describe something as minor as missing the last available ticket.
No Such Luck
Meaning:
“No such luck” is an idiomatic response meaning that something you hoped for did not happen.
In a Sentence:
“I hoped the store would still be open, but no such luck.”
Other Ways to Say It:
- Unfortunately not
- Sadly, no
- Not this time
- It didn’t happen
Explanation:
The expression is often used as a short, slightly humorous response to disappointment. It can make a negative result sound lighter than a longer explanation.
Tone: Casual, conversational, sometimes humorous.
Best Use:
Everyday conversation, storytelling, text messages, and informal writing.
Common Mistake:
“No such luck” is generally used after a hope or expectation has failed. It does not mean that luck itself does not exist.
Down on Your Luck
Meaning:
To be “down on your luck” means to be experiencing a difficult period involving bad fortune, financial problems, or other setbacks.
In a Sentence:
“After losing his job and struggling to find another, he was really down on his luck.”
Other Ways to Say It:
- Going through a rough patch
- Having a hard time
- Experiencing bad fortune
- Going through difficult circumstances
Explanation:
This expression adds emotional weight to the idea of bad luck. It usually describes a broader period of difficulty rather than one isolated unfortunate event.
Although the article focuses on good luck, understanding its opposite helps learners recognize how English speakers talk about the full range of fortune.
Tone: Emotional, sympathetic, informal.
Best Use:
Storytelling, personal conversations, journalism, and descriptive writing.
Context Note:
Because it can relate to serious financial or personal difficulties, use it with sensitivity.
Hit the Jackpot
Meaning:
“Hit the jackpot” means to have a major success or gain, often unexpectedly or through luck. It can also refer literally to winning a large prize.
In a Sentence:
“We really hit the jackpot when we found such a talented designer at the last minute.”
Other Ways to Say It:
- Strike it lucky
- Win big
- Have a major success
- Find exactly what you needed
Explanation:
The image comes from winning the largest prize in a game or gambling context. In everyday English, however, it can describe any unexpectedly excellent result, not just money.
Tone: Informal, enthusiastic.
Best Use:
Everyday conversation, storytelling, business discussions, and informal writing.
Common Mistake:
Do not assume “hit the jackpot” always involves gambling. Modern usage often describes a very successful discovery, choice, or outcome.
Strike Gold
Meaning:
“Strike gold” means to achieve major success, become wealthy, or discover something highly valuable. Cambridge also records a sporting use meaning to win a gold medal.
In a Sentence:
“The small publisher struck gold when one of its new authors became a bestseller.”
Other Ways to Say It:
- Hit the jackpot
- Find success
- Make it big
- Find something valuable
Explanation:
The figurative image comes from unexpectedly discovering gold. It therefore suggests a valuable opportunity or breakthrough that produces significant results.
Tone: Energetic, figurative, sometimes literary.
Best Use:
Business writing, journalism, storytelling, sports coverage, and conversations about major success.
Context Note:
The expression can be used beyond money. A team can “strike gold” with a successful strategy, while an athlete can literally “strike gold” by winning a gold medal.
Land on Your Feet
Meaning:
To “land on your feet” means to end up successful or lucky, especially after experiencing difficulty or uncertainty.
In a Sentence:
“She lost her old job, but she landed on her feet and found a better position within weeks.”
Other Ways to Say It:
- Come through successfully
- Recover well
- End up in a good position
- Bounce back
Explanation:
The literal image is of an animal or person falling but managing to land safely. Figuratively, it describes someone who survives a difficult situation and ends up in a favorable position.
Unlike expressions about pure chance, this idiom can also suggest resilience and practical ability.
Tone: Positive, reassuring, conversational.
Best Use:
Personal conversations, storytelling, career discussions, and informal writing.
Common Mistake:
“Land on your feet” does not necessarily mean someone was lucky from the beginning. It often emphasizes a good outcome after difficulty.
For Good Luck
Meaning:
“For good luck” is an established idiomatic expression used when something is done or kept to bring or symbolize good fortune.
In a Sentence:
“She carried the old coin for good luck during every important exam.”
Other Ways to Say It:
- As a good-luck charm
- For fortune
- To bring luck
- As a lucky symbol
Explanation:
This expression often appears alongside an object, action, or custom believed to encourage favorable fortune. It connects language with the many everyday traditions people associate with luck.
Tone: Neutral, casual, sometimes superstitious.
Best Use:
Everyday conversation, storytelling, descriptions of traditions, and personal messages.
Context Note:
The expression describes a belief or purpose. It does not claim that the object or action can objectively guarantee a particular result.
