Words That Survive Translation Perfectly (and the Science of Why)

"OK" is often called the most widely understood word on earth. We sent it through five languages and it came back as this:

Out: show.

Here is what happened to it. Watch the pivot:

In: OK
Japanese: わかりました (I understand)
Swahili: nimeelewa (I have understood)
Finnish: Ymmärrän. (I understand)
Arabic: أرى. (I see)
Hindi: दिखाओ। (show!)
Out: show.

No hop is unreasonable. "OK" is an acknowledgment, so Japanese made it "I understand," which is what you actually say. Swahili and Finnish carried that faithfully. Arabic chose "I see," also a fine way to acknowledge something. Then Hindi read "I see" as a statement about eyesight and turned it into a command to show something. The world's most universal word did not last five hops.

So we ran the experiment properly. We took 78 words through the same five language chain, English to Japanese to Swahili to Finnish to Arabic to Hindi and back, and checked which ones came home unchanged.

All results below are real output from Translation Mixer, collected in August 2026 using Google Translate as the engine.

47 of 78 survived

The pattern in the results is not the one we expected.

Food was almost a clean sweep. Chocolate, coffee, tea, sugar, banana, tomato, potato, pizza, lemon and mango all came back identical. Ten out of twelve. The two that failed were salad and soup, and we will come back to those because they failed in an unusually good way.

Basic vocabulary did worse than borrowed vocabulary. These are as common as words get, and they all broke:

Four of the five died at the same hop for the same reason. Japanese writes moon and month with one character, tree and wood with one character, house and home with one character. The word arrives, the character is correct, and the way back out picks the other meaning.

"hand" is the best of them. It went 手 to Swahili mkono to Finnish käsi, all correctly the body part, then Arabic took it as the verb and produced "He surrenders."

Meanwhile taxi, hotel, internet, robot, piano, sauna, karaoke and algebra sailed through without a scratch.

Why the borrowed words win

A word survives translation when there is exactly one thing it can mean, in every language on the route.

That sounds obvious and it is the opposite of common. Ordinary words are old, and old words accumulate jobs. Bank has money and rivers. Bar has drinks, metal rods and legal exams. Stop is a verb and a noun and a sign. Every extra job is another chance for a hop to pick the wrong one, and it only takes one.

Loanwords have not had time to accumulate anything. When a language borrows pizza, it borrows it for one purpose. It does not develop a second sense of pizza meaning "grievance" or "riverbank," because it already has words for those. The borrowed word arrives with a single referent attached and stays clean.

You can watch this fail in real time when the borrowing goes the other direction:

In: safari
Japanese: サファリ
Swahili: Safari
Finnish: Matkustaa
Out: He travels

English borrowed safari from Swahili, where it is the ordinary word for a journey. Send it back to Swahili and it stops being a specialized noun about wildlife and becomes the everyday word again, at which point Finnish quite reasonably rendered it as a verb.

The same thing happened to yoga. Hindi योग also means "sum" in mathematics, from the Sanskrit sense of joining things together, so the chain returned sum. That is not an error. It is the word's older job.

And salad, which we owe you: Arabic سلطة is both salad and authority, depending on vowels that the script does not write. The chain went in as lunch and came back as rights.

The 10 hop gauntlet

47 words survived five hops. We took 46 of them through ten, using the languages that did the most damage in our own 20 language ranking: Japanese, Mongolian, Swahili, Finnish, Arabic, Hindi, Korean, Vietnamese, Welsh and Zulu.

35 of 46 came back perfect. After ten translations.

taxi, hotel, internet, computer, virus, film, video, email, robot, doctor, hospital, university, piano, opera, pilot, chocolate, coffee, banana, tomato, pizza, mango, karaoke, guru, sauna, algebra, zero, water, mother, three, red, dog, eye, night, amen, hallelujah.

Some of those deserve a note. Amen and hallelujah are Hebrew words that ten separate languages have agreed not to translate for a couple of thousand years, which is about as good a demonstration of the one-word-one-job rule as exists. Zero traveled from Arabic sifr through Italian into English and back through Arabic without incident. Algebra is al-jabr going home.

A few of the "failures" at ten hops were not failures. tsunami came back as "The Tsunami," kimono as "a kimono," potato as "potatoes." Articles and plurals, nothing more. fire became "flame," tobacco became "cigarette," and lemon became "yellow lemon," which is drift into a neighbor rather than a break.

That leaves five genuine breaks, and three of them are the same story.

Killed by a homograph

In: tea
Japanese: お茶
Mongolian: цай
Swahili: chai
Finnish: teetä
Arabic: شاي
Hindi: चाय
Korean: 차
Vietnamese: xe hơi
Out: car

Seven languages in a row got it exactly right. Then Korean, where 차 is both tea and car, and Vietnamese read the car.

In: cotton
Korean: 면
Vietnamese: mì
Out: noodles

Korean again. 면 is cotton and it is also noodles.

In: sugar
Korean: 설탕
Vietnamese: đường
Welsh: ffordd
Out: way

Korean got sugar right. Vietnamese đường is sugar and it is also road, and Welsh took the road.

This is the sharpest result in the whole test. Tea, cotton and sugar are perfect words by our rule. One clear referent, no ambiguity in English, no ambiguity in eight of the ten languages we sent them through. They died anyway, because somewhere along a ten language route there was a language where that meaning happens to be spelled the same as something else. The word does not have to be ambiguous. The route has to be clean.

Which means survival is not really a property of the word. It is a property of the word and the path together, and the longer the path, the more chances for some language you have never thought about to have one syllable doing two jobs.

The rest of the honor roll

yes and no both broke at ten hops, and they broke with attitude:

In: yes
Out: Okay.

In: no
Vietnamese: KHÔNG
Welsh: NID YW
Out: IT IS NOT TRUE

Vietnamese capitalized it and everything downstream took the shouting seriously.

And the greeting, which we should have predicted:

In: hello
Japanese: こんにちは
Swahili: Habari
Finnish: Uutiset
Out: news

Swahili habari literally means news and is used as a greeting, the same way English "how's it going" is not a real question. Finnish took the literal meaning and the greeting was gone.

We ran ciao through the identical chain and got something better. The mixer detected the source as Italian rather than English, so it returned there instead:

In: ciao
Out: notizia

An Italian greeting went out, and Italian news came back.

Try it

The tea chain is loaded, because a word can be right eight times in a row and still come home as a car:

→ Send a word through ten languages

Single words are the fun version of this test. Try anything you think is indestructible. Brand names, foods, and words your language stole from somewhere else are the best candidates, and anything with a second meaning will not make it past hop three.
