  • “Cost an Arm and a Leg” — What It Means and How to Use It

    As an English teacher, I have been creating content for both Korean learners and global English learners. This blog is where I share the expressions and idioms I cover in my lessons — and today’s expression is one you’ll use every time something is way too expensive: “Cost an arm and a leg.”

    What does “cost an arm and a leg” mean?

    “Cost an arm and a leg” means something is extremely expensive — so expensive that it feels like you’re giving up a part of your body to pay for it.

    You use it when the price of something shocks you or feels completely unreasonable.

    Real life examples:

    1. “That new iPhone costs an arm and a leg — I’ll wait for the price to drop.”
    2. “Dinner at that restaurant cost us an arm and a leg but it was worth it.”
    3. “Flying business class costs an arm and a leg.”
    4. “I wanted to buy a house in Seoul but it costs an arm and a leg.”
    5. “Good quality coffee doesn’t have to cost an arm and a leg.”

    Where did this come from?

    This expression became popular in the 20th century. The idea is simple — your arms and legs are the most valuable things you have. If something costs that much, it must be incredibly expensive.

    Similar expressions:

    • “Break the bank” — spend more money than you can afford
    • “Doesn’t come cheap” — something is expensive
    • “Pricey” — informal word for expensive

    Quick recap:

    Cost an arm and a leg = extremely expensive. Next time you see a shocking price tag, you know exactly what to say! 💸

  • “Bite the Bullet” — What It Means and How to Use It

    As an English teacher, I have been creating content for both Korean learners and global English learners. This blog is where I share the expressions and idioms I cover in my lessons — and today’s expression is one you’ll use when life gets tough: “Bite the bullet.”

    What does “bite the bullet” mean?

    “Bite the bullet” means to endure a painful or difficult situation with courage — even when you don’t want to.

    It means pushing through something hard because you have no other choice.

    Real life examples:

    1. “I hate going to the dentist but I just had to bite the bullet and make an appointment.”
    2. “The project was stressful but we bit the bullet and finished it on time.”
    3. “Just bite the bullet and apologize — it’ll make things better.”
    4. “She bit the bullet and told her boss she needed a raise.”
    5. “Sometimes you just have to bite the bullet and do the hard thing.”

    Where did this come from?

    This expression comes from old battlefield medicine. Before modern anesthesia, soldiers who needed surgery would literally bite down on a bullet to endure the pain. It was their way of getting through something unbearable.

    Similar expressions:

    • “Tough it out” — push through something difficult
    • “Grin and bear it” — endure something unpleasant without complaining
    • “Take the plunge” — do something scary or difficult decisively

    Quick recap:

    Bite the bullet = face something hard and get through it with courage. We all have moments where we just have to bite the bullet — and come out stronger on the other side. 💪

  • “Under the Weather” — What It Means and How to Use It

    As an English teacher, I have been creating content for both Korean learners and global English learners. This blog is where I share the expressions and idioms I cover in my lessons — and today’s expression is one you’ll need whenever you’re not feeling your best: “Under the weather.”

    What does “under the weather” mean?

    “Under the weather” means feeling sick or unwell.

    You don’t have to be seriously ill — it just means you’re not feeling 100%. A little tired, a little sick, not quite yourself.

    Real life examples:

    1. “I can’t come to work today — I’m feeling a little under the weather.”
    2. “She looked under the weather at the party last night.”
    3. “I’ve been under the weather all week — probably just a cold.”
    4. “Are you okay? You seem a bit under the weather today.”
    5. “He cancelled his plans because he was feeling under the weather.”

    Where did this come from?

    This expression originally came from sailing. When sailors felt seasick, they would go below deck to be sheltered from the bad weather. Being “under the weather” meant hiding from the storm — and feeling miserable while doing it.

    Similar expressions:

    • “Not feeling well” — simple and direct
    • “Off color” — British English for feeling slightly ill
    • “Out of sorts” — not feeling quite right

    Quick recap:

    Under the weather = feeling sick or unwell. Use it when you’re not seriously ill but just not at your best. It sounds natural and very native! 🤧

  • “Hit the Sack” — What It Means and How to Use It Naturally

    As an English teacher, I have been creating content for both Korean learners and global English learners. This blog is where I share the expressions and idioms I cover in my lessons — and today’s expression is one you’ll use every single day: “Hit the sack.”

    What does “hit the sack” mean?

    “Hit the sack” means to go to bed or to go to sleep.

    It has nothing to do with hitting anything! A “sack” was an old word for a mattress or sleeping bag — so “hitting the sack” simply meant lying down to sleep.

    Real life examples:

    1. “I’m exhausted. I’m going to hit the sack early tonight.”
    2. “It’s almost midnight — time to hit the sack!”
    3. “He hit the sack as soon as he got home from work.”
    4. “You should hit the sack. You have an early morning tomorrow.”
    5. “I tried to stay up but ended up hitting the sack at 9pm.”

    When do you use it?

    Use it in casual, everyday conversation with friends and family. It’s friendly, natural, and very commonly used by native speakers.

    Similar expressions:

    • “Hit the hay” — same meaning, also very common
    • “Call it a night” — deciding to end the evening and go to sleep
    • “Catch some Z’s” — get some sleep

    Quick recap:

    Hit the sack = go to sleep. Simple, natural, and used every day by native English speakers. Try using it tonight! 😴

  • “Break a Leg” — What Does It Mean and When Do You Use It?

    As an English teacher, I have been creating content for both Korean learners and global English learners. This blog is where I share the expressions and idioms I cover in my lessons — and today’s expression is one that confuses almost every English learner the first time they hear it: “Break a leg.”

    What does “break a leg” mean?

    “Break a leg” means good luck — but you never actually want anyone to break their leg!

    It’s an idiom, which means the literal meaning and the real meaning are completely different.

    When someone is about to perform, give a presentation, or do something important, you say “break a leg” instead of “good luck.”

    Real life examples:

    1. “You’ve got your job interview today? Break a leg!”
    2. “The show starts in ten minutes — break a leg out there!”
    3. “I heard you have a big exam tomorrow. Break a leg!”
    4. “She texted me ‘break a leg’ before my presentation and it made me smile.”
    5. “Instead of saying good luck, try saying break a leg — it sounds more natural!”

    Where did this expression come from?

    There are a few theories, but the most popular one comes from the theater world. Performers believed that saying “good luck” directly would actually bring bad luck — so they said the opposite instead.

    Over time, “break a leg” became the standard way to wish someone well before a big moment.

    Similar expressions:

    • “You’ve got this” — I believe in you
    • “Knock ’em dead” — do an amazing job
    • “Go get ’em” — go do your best

    Quick recap:

    Break a leg = good luck. Use it before performances, interviews, exams, or any big moment. It sounds natural, warm, and very native! 🎭

  • What Does “Ghosting” Mean? (And Why People Do It)

    As an English teacher, I have been creating content for both Korean learners and global English learners. This blog is where I share the expressions and slang I cover in my lessons — starting with one of the most talked-about words in modern English: ghosting.

    What does “ghosting” mean?

    Have you ever texted someone and they just… disappeared?

    No reply. No explanation. Nothing.

    That’s called ghosting — suddenly cutting off all communication with someone without any warning or reason. One day they’re there, the next day they’re completely gone — like a ghost.

    It can happen in dating, friendships, or even at work.

    Real life examples:

    1. “I thought we had a great date, but then he ghosted me.”
    2. “She ghosted all her friends after moving to a new city.”
    3. “I applied for the job and they just ghosted me — no email, nothing.”
    4. “Don’t ghost me! Just tell me if you’re not interested.”
    5. “He’s been ghosting my texts for a week now.”

    Why do people ghost?

    • They want to avoid conflict
    • They don’t know how to say goodbye
    • They lose interest but feel awkward being honest

    Similar expressions:

    • Go MIA (Missing In Action) — suddenly unreachable
    • Left on read — they saw your message but didn’t reply
    • Soft ghosting — still watching your stories but never replies

    Quick recap:

    Ghosting = disappearing without explanation. It hurts, it’s confusing — but now you know exactly what to call it.
