“Luck” Expressions in English

Luck Expressions in English (10 Useful Idioms with Examples)

Luck is a strange thing. Sometimes it saves us at the last moment. Sometimes it changes our lives completely. And sometimes… it just helps us find the right page in a book. English is full of expressions about luck, chance, coincidence, and opportunity — and native speakers use them all the time in both everyday conversation and writing.

In this lesson, you will learn 10 very common and useful “luck” expressions in English, with clear meanings and natural example sentences you can start using straight away. These are especially useful for B2 First (FCE), C1 Advanced (CAE), and for sounding more natural in real life.

Let’s begin.

Twist of fate

Meaning: an unexpected change in events, often something surprising or dramatic.

• By a strange twist of fate, they met again years later in New York.
• By a twist of fate, the job she almost didn’t apply for changed her whole life.

Meaning: something good that happens unexpectedly.

• Finding my lost wallet was a real stroke of good luck.
• It was a stroke of good luck that he arrived just in time to help us.

Golden opportunity

Meaning: an excellent opportunity that may not happen again.

• We’re waiting for the results now, so we’re keeping our fingers crossed.

Lucky guess

Meaning: a correct answer or decision made by chance, not by knowledge.

Fall into your lap

Meaning: to get something good without making any effort.

• Opportunities like that don’t usually fall into your lap.

These expressions help you sound more natural and idiomatic, express chance, luck, coincidence, and opportunity more precisely, and write or speak in a more advanced, B2–C1 style.

Instead of saying:

• I was lucky.

You can say:

• It was a real stroke of good luck.
• By a twist of fate, everything changed.
• It was a golden opportunity, so I jumped at the chance.

Luck may be unpredictable — but your English doesn’t have to be. The more expressions like these you learn, the richer, more natural, and more confident your English becomes.

And now… fingers crossed that you start using them in your next conversation. 🍀
