Scripts Are Not Decoration And They Are Not Interchangeable

Different writing systems encode different sound structures and carry different histories of use.

A script is often the first visible signal that you have crossed into different linguistic territory, because it changes on signage before anything else does. It is tempting for a reader who does not use these systems to see the shapes as ornamental, a stylistic variation on writing. They are not. Each is a working technology with its own rules for how sounds combine, how vowels attach to consonants, how a syllable is bundled into a single visual unit. Some of these systems share a family resemblance and some do not, and the resemblance does not track how similar the spoken languages are.

There is also the awkward fact that script and language do not map one to one. A single script can serve several languages, and a single language can be written in more than one script depending on region and habit. So the sign above a shop tells you something, but not everything, and certainly not what you would guess if you assumed one country, one alphabet. Learning to read a script is a separate achievement from learning to speak the language it usually carries, and plenty of people have done one without the other.

For a visitor to writing rather than speech, this is where the internal variety becomes physically visible. Walk a street where several scripts appear on adjacent buildings and you are looking at layered histories of trade, administration, education and migration, all of them written out in public and all of them still in daily use. It is the most legible evidence available that the single word on the map is doing far too much work.
