Language is humanity’s oldest technology — and one of its strangest. There are thousands of living tongues, each with its own grammar, sounds and ways of seeing the world, and the work of carrying meaning between them has shaped history in ways most people never notice. Here is a collection of our favourite facts about languages, alphabets, translators and the quirks that make translation endlessly fascinating.
🌍
7,000+ languages are spoken today
Papua New Guinea alone has over 840 languages — more than any other country. Many of the world’s languages have fewer than 1,000 speakers, and roughly one disappears every few weeks.

📖
The Bible is the most translated book ever
It has been translated, in full or in part, into well over 700 languages. “The Little Prince” comes a distant second with 380+ translations, followed by “Pinocchio.”

Klingon is a fully developed language
Created for Star Trek by linguist Marc Okrand, Klingon has its own dictionary, grammar rules and an institute — and even Shakespeare’s “Hamlet” has been translated into it.
Fun Fact

The Rosetta Stone cracked the code
Discovered in 1799, this ancient slab carried the same decree in three scripts. By comparing the known Greek with the unknown symbols, scholars finally deciphered Egyptian hieroglyphics.
History
🇩🇪
English is full of “borrowed” words
“Kindergarten,” “wanderlust” and “doppelgänger” are German. “Café” is French. Linguists estimate the majority of English vocabulary was borrowed from other languages.

🤯
Some words are “untranslatable”
Japanese “tsundoku” means buying books and never reading them. Finnish “kalsarikännit” means drinking at home, alone, in your underwear, with no intention of going out.
Fun Fact

Cambodian has the longest alphabet
The Khmer alphabet has 74 letters, making it the world’s largest. At the other extreme, Rotokas in Papua New Guinea gets by with just 12.

Translators shaped world history
A mistranslation of the Japanese word “mokusatsu” in 1945 — read as “ignore with contempt” rather than “no comment” — may have influenced the course of the end of WWII.
History
🗣️
Mandarin has the most native speakers
Around 900 million people speak Mandarin Chinese as a first language. English leads when second-language speakers are counted, with well over a billion total users worldwide.
Record
🤖
The word “robot” came from a play
It was coined from the Czech “robota,” meaning forced labour, in Karel Čapek’s 1920 science-fiction play R.U.R. The word spread into nearly every language on Earth.
Fun Fact
📜
Icelandic has barely changed in 1,000 years
Thanks to its isolation, modern Icelanders can still read the medieval sagas written by their ancestors a millennium ago — something almost no other European language can claim.
History

Sign languages are full languages
There are more than 300 distinct sign languages, each with its own grammar and regional dialects. American Sign Language and British Sign Language are mutually unintelligible.

Esperanto was built for world peace
Invented by L. L. Zamenhof in 1887, Esperanto is the most widely spoken constructed language, with an estimated two million speakers and even a few thousand native ones.
Fun Fact
👌
“OK” may be the world’s best-known word
Recognised in nearly every language, “OK” likely began as a jokey 1830s abbreviation of “oll korrect” in Boston newspapers before conquering the globe.

Why translation matters more than ever
Every day, billions of messages cross language borders: a traveller reading a menu, a student following a lecture, a business signing a contract, a family staying in touch across continents. Translation is the quiet infrastructure that makes all of it possible, and the better it gets, the smaller the world feels.
Machine translation has come a long way from the clumsy word-for-word systems of a few decades ago. Modern tools understand context, idioms and tone far better, but human nuance still matters — a phrase that is perfectly correct can still be completely wrong for the moment. That gap between “accurate” and “right” is exactly what makes language so endlessly interesting.
A few tips for better translations
- Keep sentences short and clear — long, tangled sentences confuse both humans and machines.
- Avoid slang and idioms when you need a precise result; they rarely survive the trip intact.
- Watch out for words with several meanings, and add context where you can.
- Always proofread an important translation, ideally with a native speaker.
