English idioms about body parts are some of the most useful \u2014 and most-quoted \u2014 expressions in everyday conversation. Native speakers reach for them constantly. They turn up in movies, in business meetings, in social media captions, and in the kind of fast-paced small talk that ESL textbooks rarely prepare students for. If your learners can decode cost an arm and a leg<\/em>, get cold feet<\/em>\uff0c \u548c pull someone’s leg<\/em>, they will sound dramatically more natural and understand a huge chunk of native speech they would otherwise miss.<\/p>\n

That shared anchor makes the figurative leap much easier than abstract idioms about time, fate, or success. Below are ten high-frequency body-part idioms \u2014 grouped by the part they reference \u2014 with clear meanings, the real stories behind them, and example sentences you can drop straight into your next lesson plan.<\/p>\n

10 Body-Part Idioms You Need to Know<\/h2>\n

1. Cost an Arm and a Leg<\/h3>\n

\u610f\u4e49\uff1a<\/strong> Extremely expensive \u2014 so costly that the price feels painful. Native speakers use this when something is shockingly overpriced, especially compared to what they expected to pay.<\/p>\n

\u8d77\u6e90\uff1a<\/strong> The phrase first appeared in American newspapers shortly after World War II. One popular theory traces it to soldiers who returned from the front having literally lost limbs \u2014 making lost arms and legs a vivid measure of an enormous cost. Another theory points to early American portrait painters who reportedly charged extra to include hands, arms, and legs in a painting; cheap portraits showed only the head and shoulders. Either way, the idiom was firmly established in everyday English by the 1950s.<\/p>\n

\u4f8b\u5982\uff1a<\/strong><\/p>\n

    \n
  • “That handbag looks gorgeous, but it cost me an arm and a leg.”<\/li>\n
  • “Sending all three kids to private school would cost an arm and a leg \u2014 we’d never afford it.”<\/li>\n<\/ul>\n

    \u4f7f\u7528\u63d0\u793a\uff1a<\/strong> Common in informal speech, casual emails, and even business chats. Pair it with intensifiers like “absolutely” or “literally” for emphasis.<\/p>\n

    2. Pull Someone’s Leg<\/h3>\n

    \u610f\u4e49\uff1a<\/strong> To joke or tease someone playfully, usually by telling them something untrue to see how they react. It is light-hearted, not malicious.<\/p>\n

    \u8d77\u6e90\uff1a<\/strong> Etymologists are not certain, but the most popular story dates from 18th and 19th-century Britain, where street thieves would literally trip victims by tugging their legs with a hook or stick before robbing them. Over time, “pulling the leg” softened into a playful trick rather than a violent one. By the late 1800s, the phrase appears in print describing harmless teasing.<\/p>\n

    \u4f8b\u5982\uff1a<\/strong><\/p>\n

      \n
    • “Don’t worry, I’m just pulling your leg \u2014 your presentation was actually great.”<\/li>\n
    • “Are you pulling my leg, or did you really meet the CEO at the coffee shop?”<\/li>\n<\/ul>\n

      \u4f7f\u7528\u63d0\u793a\uff1a<\/strong> Use it to defuse a joke that landed too hard. “I’m pulling your leg” instantly signals you weren’t serious.<\/p>\n

      3. Get Cold Feet<\/h3>\n

      \u610f\u4e49\uff1a<\/strong> To become nervous or hesitant about something you had planned to do, often at the last minute. Used most famously for weddings, but also for job offers, big purchases, or any major commitment.<\/p>\n

      \u8d77\u6e90\uff1a<\/strong> The expression appears in Stephen Crane’s 1896 novel Maggie: A Girl of the Streets<\/em>, but its roots stretch further. One theory traces it to Italian gamblers who would claim cold feet as an excuse to leave a card game they were losing. Another links it to soldiers whose frozen feet kept them out of battle. By the early 20th century, “cold feet” was the standard English way to describe sudden loss of nerve.<\/p>\n

      \u4f8b\u5982\uff1a<\/strong><\/p>\n

        \n
      • “He’s been planning this trip for months, but now he’s getting cold feet about flying alone.”<\/li>\n
      • “Sarah got cold feet the morning of the wedding and almost called the whole thing off.”<\/li>\n<\/ul>\n

        \u4f7f\u7528\u63d0\u793a\uff1a<\/strong> Often used with “get” or “have.” Avoid in formal writing \u2014 it’s distinctly conversational.<\/p>\n

        \u8d77\u6e90\uff1a<\/strong> This Americanism first appeared in print in the 1930s. The image is of words coming straight out of your head without passing through the slower, more deliberate parts of thought. It became hugely popular in business and journalism because it lets the speaker offer information while admitting it might be wrong.<\/p>\n

        \u4f8b\u5982\uff1a<\/strong><\/p>\n

          \n
        • “Off the top of my head, I’d say we have about thirty registered users \u2014 but let me check.”<\/li>\n
        • “I can’t remember her exact title off the top of my head, but I think she’s a senior designer.”<\/li>\n<\/ul>\n

          \u4f7f\u7528\u63d0\u793a\uff1a<\/strong> Great hedge phrase for meetings and interviews \u2014 it shows confidence without overcommitting.<\/p>\n

          \u8d77\u6e90\uff1a<\/strong> First recorded in the early 20th century, the idiom borrows from the literal experience of a stiff or aching neck \u2014 a small but persistent annoyance you can’t ignore. The crasser variations came later, but “pain in the neck” remains the polite version teachers and parents prefer.<\/p>\n

          \u4f8b\u5982\uff1a<\/strong><\/p>\n

            \n
          • “Filling out this tax form is a real pain in the neck.”<\/li>\n
          • “My downstairs neighbor is a pain in the neck \u2014 he plays the drums at midnight.”<\/li>\n<\/ul>\n

            \u4f7f\u7528\u63d0\u793a\uff1a<\/strong> Acceptable in workplace conversation. For stronger irritation, native speakers sometimes substitute body parts further south \u2014 but stick with “neck” in mixed company.<\/p>\n
