Your body does a lot more than move you around; it even slips into the way you talk. From head to toe, clever idioms using body parts are a staple of everyday conversation. If you want to learn more about what these 10 idioms really mean and how they started, keep reading!

After the argument, she kept her coworker at arm’s length to avoid more drama.

Remember that friend-of-a-friend you’re not so sure about? The one you’d rather not let get too close? That’s someone you keep "at arm’s length." This common phrase comes from the old practice of measuring distances with body parts (not so old, really; we still measure in feet), and an early version even shows up in Shakespeare’s 1599 play As You Like It, where the line goes: "Hold death awhile at arm’s end."

When my car broke down, a kind stranger stopped to lend me a hand.

Many expressions we use figuratively today started out in very literal situations. That’s the case with "to lend a hand," which originally referred to physically using your hands to help someone with a task. Over time, the meaning expanded, and the phrase can now be used for any kind of help.

His birthday is on the tip of my tongue… wait, is it next Thursday?

You’re chatting with your best friend, remembering old times, when a familiar song pops into your head. You remember the lyrics perfectly, but who was the singer? Ahh… It’s on the "tip of your tongue"! Used in English since the 16th century, this idiom describes those moments when something feels just within reach but doesn’t fully come to mind.

Ever since they met, he’s been head over heels for her.

When was the last time you were completely captivated by someone or something? In those moments, you could say you were "head over heels." The phrase dates back to 14th- and 15th-century English as "heels over head," originally describing literal upside-down movements. Over time, it evolved into its modern form, describing the feeling of being madly in love.

I’d give my eye teeth to get tickets to that concert!

In the past, canines (often called eye teeth because they sit just below the eyes) were among the most important teeth. Losing one was a big deal, which likely explains the origin of this idiom. It’s still used today to describe a major sacrifice or something someone desperately wants.

I bet your ears are burning after that email went around the office.

It turns out your ears can "burn" even when there’s no infection. This kind of burning has a different interpretation: it means someone is talking about you behind your back. It’s not always negative, but it does involve gossip. The idiom comes from ancient beliefs that physical sensations in the body could indicate external events.

Renovating the old house is going to cost us an arm and a leg.

When something costs an arm and a leg, it means it’s extremely expensive or requires a big sacrifice. There are two main theories about its origin: one, now widely regarded as a myth, suggests that in the 15th century, artists charged more if a portrait included the subject’s arms or legs. The other theory links the phrase to the serious physical sacrifices soldiers can make in war.

Break a leg at the competition; everyone’s rooting for you.

When you tell your singer friend to "break a leg," you’re not wishing them anything bad; in fact, it’s the opposite. This idiom comes from old theater superstitions, where saying "good luck" was thought to bring exactly the contrary. To avoid tempting fate, people would say something negative to actually wish someone something positive.

He cried his heart out after saying goodbye to his childhood home.

Since ancient times, people have believed that the heart is where emotions live. So when you "cry your heart out," you’re letting out all your feelings, often very intensely. The phrase usually reflects pain, sadness, ordeep emotional suffering.

Even though we argued, he’s still my flesh and blood, and I’ll always protect him.

This idiom is much less creepy than it might sound at first. To be someone’s "flesh and blood" means you are part of their family, or are treated as if you were. Some sources trace one of the earliest uses of this phrase to an Old English translation of the Bible, specifically in Matthew 16:17.

Evolution of terms

Original names of everyday things that we left behind

Would you know what to give a person if they asked you to pass them the "clicker"? And would you say that you know how to safely handle a "range"? Some objects we see every day had very different names in their early days. So we’ve made a list of nostalgic terms that we stopped using over time. See if you know them all!

Why would you call a remote control a clicker? Simple: because of the sound it made when used. The original versions weren’t even electronic; instead, some used mechanical hammers that emitted a high-pitched click to signal the TV and control it remotely.

Before the devices we know today, shaving was a delicate art performed with straight blades. These were known as cut-throat razors, for obvious reasons.

Later, popularized by King C. Gillette in the early 1900s, the safety razor featured a protective guard to prevent deep cuts and made shaving safer for home use. Today, we just call them "razors" or call them by their brand.

Did your grandparents ever tell you to "put on your galoshes"? During the 19th century, the term referred to rubber overshoes worn to protect regular shoes from rain and mud. As waterproof rubber footwear (what we now call rain boots) became more widespread, many people began using galoshes to refer to those as well.

Old refrigerators where people cooled their perishables were known as iceboxes. They looked like wooden cabinets with metal linings inside, and contained large blocks of ice, which were delivered regularly by icemen. The ice sat in a compartment at the top, keeping food cool as it slowly melted, with runoff collected in a tray underneath.

As with galoshes, the term icebox continued to be used even after electric refrigerators became the norm.

Long before denim and jeans became the go-to terms, these work pants were often called dungarees. The name was less a nod to style or cut than to durability and purpose.

The term comes from Dongri, a dockside village near Mumbai, India, where a coarse, durable cotton fabric was produced and exported by the British in the 17th century. When the blue, strong fabric we know as "denim" became widespread, it made sense to call these garments the same way rugged pants had always been called.

You might be thinking, "Don’t we still use that word?" Of course we do. But there was a time when very few homes on the block had the technology to receive phone calls at all.

During the late 20th century, as portable telephones became widespread, a new term was required to refer to the phones with physical cables connected to underground networks. Thus, the word landline emerged to differentiate them from mobile phones.

"Spectacles" might sound quaint today, but for a long time, it was the standard word for a vision-correcting device. Early lenses were handheld and were introduced in Europe in the late 13th century!

The switch to the term glasses began in the 20th century, as optical glass became the standard lens material, and gained popularity largely through colloquial shortening.

Before Spotify playlists and digital shuffles, music lovers gathered around a turntable spinning at the center of the room. This was the common term for the rotating platform used to play vinyl records. Today, as vinyl has made an unexpected comeback, the term is often replaced in casual speech by record player.

This is another word we still use frequently, though its meaning has shifted over time. When typewriters were a must in every office, people often referred to the entire machine simply as **the keyboard**—a classic example of synecdoche.

Of course, the term keyboard was carried over from typewriters, and now we use it to refer mostly to the QWERTY set of keys.

Range was once the common term for a large cooking appliance with multiple burners and compartments—in other words, a long, horizontal cooking surface that could "range" across different heat zones.

As gas and electric stoves became more compact and widely accessible in the 20th century, stove increasingly replaced range in everyday speech.

Today, the word wireless brings to mind Wi-Fi or Bluetooth-connected headphones. But many technologies were "wireless" long before that. Early radio, in fact, was commonly referred to as wireless.

In the late 19th and early 20th centuries, radio was known as wireless telegraphy because it allowed messages to be transmitted without physical wires. The term gradually faded as the technology evolved, and radio became the standard term by the 1930s.
