A Technology, Not a Faculty
Every human population has spoken or signed language. Writing is a Technology rather than an innate biological faculty. It was independently invented perhaps four times: Mesopotamia (3200 BCE), Egypt (3200 BCE), China, and Mesoamerica.
Children acquire speech naturally, but writing requires explicit instruction. Linguistics treats speech as primary and writing as secondary.
The Types
| Type | Unit represented | Example |
|---|---|---|
| Logographic | Morpheme or word | Chinese characters |
| Syllabic | Syllable | Japanese kana |
| Alphabetic | Consonant and vowel | Latin, Cyrillic |
| Abjad | Consonant only | Arabic, Hebrew |
| Abugida | Consonant + inherent vowel | Devanagari |
The alphabet was invented only once. It arose in the Semitic world around 1800 BCE, before the Greek addition of vowels around 800 BCE. Korean Hangul, devised in 1443, is a rare independent featural system.
Orthographic Depth
Orthographies differ in how consistently symbols map to speech sounds:
- Shallow: regular sound-letter correspondence (e.g., Spanish, Finnish). Pronunciation is predictable from spelling.
- Deep: irregular sound-letter correspondence (e.g., English, French).
English has roughly 40 phonemes, but hundreds of spellings for them. Children learn to read faster in shallow orthographies than in deep ones.
Common pitfall: believing an alphabet is inherently superior to a logography. Chinese characters work brilliantly for dialects with identical meanings but different pronunciations. Fit to the language matters most.
