My classroom has a running joke: whenever a student learns that I spent three months teaching in South Korea, they immediately ask, “Must have cost you an arm and a leg!” What I love about that moment is that it’s a perfect teachable instant — they’ve just used an idiom, often without realizing it. Body idioms like this are woven through everyday English, and once you recognize them, you’ll notice them everywhere in films, podcasts, and real conversations.
You’ll breaks down 10 of the most frequently used body idioms in English. I’ve grouped them by which body part they mention, added practical examples you’ll actually hear, and included a quick dialogue that shows how native speakers use them naturally. Each idiom comes with both its figurative meaning and why learners sometimes trip up on it.
Key Takeaways
- Figurative vs. literal — body idioms describe emotions, situations, or actions using body parts as metaphors.
- Regional variation — some idioms differ between US and UK English (e.g., “put your foot in your mouth” vs. “put your foot in it”).
- Frequency matters — idioms like “cost an arm and a leg” and “put your foot in it” appear constantly in native speech.
- Context tells the story — the same idiom can shift meaning slightly depending on tone and situation (e.g., “go to your head”).
- Learn them in clusters — grouping idioms by body part helps your brain anchor them together.
Understanding Body Idioms
An idiom is a phrase or expression that has a meaning different from what the individual words suggest. Body idioms specifically use body parts — hands, feet, head, chest, arms, legs, fingers — as metaphors to describe feelings, situations, or actions. When someone says “Put your foot in it,” they don’t literally mean step into something; they mean they’ve said something inappropriate by accident.
The challenge with body idioms is that non-native speakers often try to translate them word-for-word, which creates confusion. A learner from Brazil once asked me seriously, “If I cost an arm and a leg, should I worry?” — the literal interpretation made no sense to her, but once we unpacked the idiom as “very expensive,” the light went on.
Literal vs. figurative: Body idioms are almost always figurative. The speaker is not talking about actual body parts; they’re using the image to convey emotion or situation. This is the key to remembering them.
Tip: When you encounter a new idiom, ask yourself: “Does this make literal sense?” If not, it’s probably figurative. The image (arm, leg, head) is just a vehicle for the real meaning.
10 Essential Body Idioms with Examples
1. Give Your Right Arm
Pronunciation: /ɡɪv jɔːr raɪt ɑːrm/ — phrasal idiom (informal)
Meaning: To want something so badly that you would be willing to sacrifice almost anything for it.
Example 1: I would give my right arm to meet Beyoncé in person.
Example 2: She said she’d give her right arm to travel around the world.
Origin: The idiom relies on the fact that losing your right arm would be a tremendous sacrifice (for a right-handed person), so it emphasizes how much you desire something.
2. Put Your Foot in It / Put Your Foot in Your Mouth
Pronunciation: /pʊt jɔːr fʊt ɪn ɪt/ — phrasal idiom (informal)
Meaning: To say something by accident that embarrasses or upsets someone, or to blunder in what you say.
Example 1: I really put my foot in it with Alison. I had no idea she was divorced.
Example 2: At the dinner party, he put his foot in his mouth when he asked how the CEO’s new startup was failing.
Note: “Put your foot in your mouth” is more common in US English; “put your foot in it” is preferred in British English.
Remember: If you’ve made an awkward social blunder, you can say, “I’ve put my foot in it again” — it shows self-awareness and often gets a laugh.
3. Pull Someone’s Leg
Pronunciation: /pʊl ˈsʌmwʌnz leɡ/ — phrasal idiom
Meaning: To joke with someone or try to persuade them to believe something untrue as a joke.
Example 1: Is it really your car, or are you pulling my leg?
Example 2: When my friend told me he’d won the lottery, I thought he was pulling my leg.
Origin: The exact origin is unclear, but it may relate to the image of someone literally tripping someone else up by pulling their leg as a prank.
4. Put Your Finger on Something
Pronunciation: /pʊt jɔːr ˈfɪŋɡər ɒn ˈsʌmθɪŋ/ — phrasal idiom
Meaning: To discover or identify the exact cause or reason for something, especially when diagnosing a problem.
Example 1: There’s something odd about the report, but I can’t quite put my finger on it.
Example 2: The teacher put her finger on the exact problem with my essay — I wasn’t supporting my arguments with evidence.
5. Come to a Head / Bring Something to a Head
Pronunciation: /kʌm tə ə hed/ — phrasal idiom
Meaning: When a situation reaches a critical point where something must be done about it; when tension or conflict can no longer be ignored.
Example 1: Things hadn’t been good between us for a while, and this incident just brought it to a head.
Example 2: The budget crisis came to a head when the board demanded answers.
6. Go to Someone’s Head
Pronunciation: /ɡoʊ tə ˈsʌmwʌnz hed/ — phrasal idiom
Meaning 1: If success, fame, or power goes to someone’s head, it makes them become arrogant or less pleasant.
Example 1: Don’t let winning the tournament go to your head — there are still better players out there.
Meaning 2: If alcohol goes to your head, it intoxicates you quickly.
Example 2: Champagne always goes straight to my head after just one glass.
7. Cost an Arm and a Leg / Cost a Small Fortune
Pronunciation: /kɔːst ən ɑːrm ən ə leɡ/ — phrasal idiom (informal)
Meaning: To be extremely expensive.
Example 1: Designer handbags cost an arm and a leg, but they last forever.
Example 2: Flying to Tokyo during cherry blossom season costs a small fortune.
Regional note: In UK English, you might also hear “cost a bomb,” “cost the earth,” or “cost a packet.”
8. Find Your Feet
Pronunciation: /faɪnd jɔːr fiːt/ — phrasal idiom
Meaning: To become familiar with and confident in a new situation; to adjust and settle in.
Example 1: It took me about three months to find my feet in my new job, but now I’m thriving.
Example 2: New students usually find their feet by the end of the first semester.
9. Bury or Have Your Head in the Sand
Pronunciation: /ˈberɪ jɔːr hed ɪn ðə sænd/ — phrasal idiom
Meaning: To refuse to acknowledge or deal with an unpleasant problem or reality.
Example 1: You can’t just bury your head in the sand — you have to face the fact that you’re failing the class.
Example 2: Many companies have their head in the sand about climate change, even though the evidence is overwhelming.
Origin: This comes from the (incorrect) myth that ostriches bury their heads in the sand when scared.
10. Get Something Off Your Chest
Pronunciation: /ɡet ˈsʌmθɪŋ ɔːf jɔːr tʃest/ — phrasal idiom
Meaning: To tell someone about something that has been worrying you or making you feel guilty for a long time.

Common Mistakes with Body Idioms
✗ Incorrect: I would give you my right arm for a new phone.
✓ Correct: I would give my right arm for a new phone.
Why: The idiom uses the possessive “my,” not “you” as the object. You’re talking about your own sacrifice.
✗ Incorrect: She put her feet in it when she mentioned his ex-girlfriend.
✓ Correct: She put her foot in it when she mentioned his ex-girlfriend.
Why: “Foot” is singular in the idiom, even though you have two feet. The phrase is “put your foot in it,” not “feet.”
✗ Incorrect: Are you pulling my arms?
✓ Correct: Are you pulling my leg?
Why: The idiom specifically uses “leg,” not any random body part. The image is tied to one particular limb.
Common trap: Learners sometimes try to create new idioms by substituting body parts (e.g., “cost a head and a hand”), but idioms are fixed expressions — you can’t just swap words around and expect them to work.

Why Body Idioms Matter in English
When you watch a film or listen to a podcast, you’ll hear body idioms constantly. Native speakers use them because they’re vivid, memorable, and often funny. Understanding them makes you sound more natural in conversation, and it helps you comprehend native speakers without constantly asking “What does that mean?”
More importantly, idioms reveal how languages reflect culture and shared human experience. The fact that English uses “get it off your chest” for relief, or “cost an arm and a leg” for expense, tells you something about how English speakers conceptualize emotions and value. Learning idioms isn’t just vocabulary — it’s a window into how native speakers think.

Frequently Asked Questions
Why are body idioms so common in English?
Body idioms are common because they create vivid mental images that are easy to remember. Instead of just saying “very expensive,” saying “costs an arm and a leg” paints a picture in your mind — it’s memorable, and it connects to shared human experience (the value of our limbs, the cost of sacrifice).
Can I use body idioms in formal writing?
Most body idioms are informal and best suited for conversation, emails to friends, or creative writing. In academic papers or professional reports, avoid idioms and use literal language instead. However, in business emails or internal memos, a light idiom can add personality without being unprofessional.
Do body idioms change between American and British English?
Yes, some do. For example, Americans say “put your foot in your mouth,” while British speakers prefer “put your foot in it.” The meanings are the same, but the phrasing varies. When learning, it helps to know both versions so you understand what anyone means.
What’s the best way to learn and remember body idioms?
Group them by body part (head idioms, foot idioms, arm idioms), write sentences using them, and practice them in conversations with native speakers or in writing. The more you use them, the more automatic they become — you’ll stop thinking about the literal meaning and just use them naturally.
If I use a body idiom incorrectly, will native speakers understand me?
Usually, yes — context helps. But misusing an idiom can make you sound unnatural or even unintentionally funny. That’s why it’s worth learning them correctly. Native speakers don’t judge learners harshly, but getting it right shows you’re progressing in your English fluency.
