How does a rigid, comprehensive, and prescriptive grammar ensure accurate oral transmission of linguistic works across generations? How does such a grammar prevent semantic shifts across time?
Imagine you had to pass down a Java program (through oral tradition) to sort numbers and you had a Java Language Specification that remains unchanged. Now compare that to say English language where and you write an essay on sorting numbers. If both things are passed down orally over few dozen generations which one is likely to keep its form ?
