How to Learn These 100 Idioms
Step 1: Don’t memorize all 100 at once. Pick one topic (10 idioms) per week. Spend the week encountering those idioms in movies, podcasts, and articles.
Step 2: Write personal sentences. For each idiom, write 2–3 sentences about your own life. “I got butterflies in my stomach before my driving test” is memorable. Generic examples are not.
Step 3: Notice idioms in real English. Once you start looking, you’ll see these idioms everywhere — in TV shows, news headlines, social media, and conversations. Each natural encounter strengthens your memory.
Step 4: Use spaced repetition. Add these idioms to your Linglify vocabulary for automatic review at the optimal intervals.
Step 5: Use them actively. Start with the safest, most universal idioms: at the end of the day, get the ball rolling, on the same page, in a nutshell. Use them in emails, conversations, and writing.

FAQ
What are the 10 most commonly used idioms?
Based on frequency in spoken and written English: at the end of the day, a piece of cake, break the ice, on the same page, time flies, in a nutshell, the bottom line, get the ball rolling, cost an arm and a leg, bite the bullet. These are safe to use in almost any English conversation — professional, academic, or casual.
What is the difference between an idiom and a proverb?
An idiom is a phrase whose meaning differs from its literal words (“spill the beans” = reveal a secret). A proverb is a complete sentence expressing a general truth (“Don’t put all your eggs in one basket” = don’t risk everything on one plan). Proverbs give advice; idioms describe situations. Many proverbs are also idiomatic, making the distinction blurry in practice.
Can I use idioms in IELTS Speaking?
Yes — and you should. Using 2–3 natural idioms in the IELTS Speaking test demonstrates vocabulary range and can boost your score. Use common, widely understood idioms (“at the end of the day,” “a piece of cake”) rather than obscure ones. Forced or incorrect idiom use will lower your score. For IELTS-specific idioms, see Idioms for IELTS Speaking.
How long does it take to learn 100 idioms?
At a pace of 10 idioms per week with daily review, you can learn all 100 in approximately 10 weeks. However, “learning” means active use — being able to use the idiom naturally in your own sentences, not just recognizing it. Recognition takes 2–3 exposures; production takes 8–10. Using spaced repetition accelerates the process significantly.
Are idioms the same in British and American English?
Most common idioms are shared between British and American English. However, some are specific to one variety: “Bob’s your uncle” (British), “hit a home run” (American). For British-specific expressions, see British Slang Words: 200+ Expressions. The 100 idioms in this list are universally understood in both varieties.
