A sign in an unknown language is not an obstacle. It is a coordinate.
You are not trying to translate. You are trying to answer one question: which writing system is this? Get that right and you have narrowed the world to a region, and sometimes to a single country.
The classification takes about three seconds, and the list you need to carry in your head is shorter than you think.
The fast triage
Work by shape first. You are reading the outline of a block of text across the street, not deciphering a letter.
- Latin
- The most common and the least useful on its own — the Americas, Western and Central Europe, much of Africa, Southeast Asia and Oceania. Go straight to the diacritics.
- Cyrillic
- Angular, with recognisable characters such as
Д,Ж,Я,Ъ,Ф. Russia, Ukraine, Belarus, Bulgaria, Serbia, North Macedonia, Mongolia and parts of Central Asia. - Arabic
- Flowing, connected, right-to-left, with heavy use of dots above and below the line. North Africa and the Middle East, and in modified forms Iran, Pakistan and Afghanistan.
- Devanagari
- A horizontal bar runs along the top of the line and the characters hang beneath it. Northern India and Nepal.
- Thai
- Rounded and loopy with small circular flourishes, plus marks stacked above and below the line. Dense and busy-looking.
- Khmer
- Taller and more angular than Thai, with elaborate curling forms. If it looks like Thai but sharper and more vertical, check Khmer.
- Lao
- Rounder and visually simpler than Thai, with fewer stacked marks.
- Burmese
- Almost entirely circular forms — the most obviously round script in the world.
- Hangul
- Korean. Characters built into square blocks that combine circles, rectangles and short strokes. Unmistakable once you have seen it.
- Han
- Dense, boxy, complex glyphs. On their own, lean China or Taiwan.
- Greek, Georgian, Armenian, Hebrew, Geʽez
- Each is effectively a one- or two-country tell.
The pairs that catch people out
The Southeast Asian scripts are where beginners lose rounds. Thai, Khmer and Lao share a visual family, so decide on proportion rather than detail: Thai is round and busy, Khmer is tall and sharp, Lao is round and sparse.
The other classic pair is Han against Japanese. If every glyph in frame is dense and boxy, you are in China or Taiwan. If those complex glyphs are mixed with simpler, curvier characters in the same line, that is kana beside kanji — which is Japan.
Several scripts are effectively single-country tells. Learn to recognise them and you collect free rounds.
When it is Latin, go to the diacritics
Most of the world writes in Latin script, so the real work is in the marks above and below the letters. One accent is worth more than a whole street of unmarked text.
| Marks in the text | Where it points |
|---|---|
Ł, Ż, Ś, Ć, Ą, Ę | Polish |
ș, ț, ă, â, î | Romanian |
ı (dotless i), ğ, ş | Turkish |
å, ø, æ | Danish and Norwegian |
å, ä, ö | Swedish and Finnish |
ñ | Spanish and several others |
ã, õ, ç | Portuguese |
č, š, ž | Czech, Slovak, Slovene, Croatian, the Baltic languages |
đ, ư, ơ plus stacked tone marks | Vietnamese |
Vietnamese is the easiest of these to call from a distance: Latin letters carrying an unusual density of accent marks, frequently stacked on top of each other. You can spot it before you can focus on a single word.
What to do when there is no text
Look harder. Text hides in places people forget to check.
- Van doors and delivery vehicles
- Shop awnings and roller shutters
- Graffiti and stickers on poles
- Bin lids and utility box stencils
- Road markings and painted kerb text
- Election posters and fly-posted advertising
- The small print along the bottom edge of road signs
If the frame is genuinely textless, stop hunting and fall back to infrastructure. Bollards, utility poles and line paint are present on almost every road in the inhabited world, and unlike signage they never get taken down.
