Perhaps you're interested in exploring a scenario where:
* Dictionaries had never existed: This would be a fascinating world where language evolved in different ways. Without a standardized reference, regional dialects and slang could proliferate, making communication between different groups challenging. Literature and education might be significantly impacted, with the absence of a common understanding of words and their meanings.
* Dictionaries were invented in a different way: Imagine a dictionary that organized words by their emotional impact, or by their history, or even by their sound. What kind of impact would this have on our understanding of language?
* Dictionaries were invented with a different purpose: Perhaps dictionaries were created not to define words, but to control their use, or to promote specific ideologies. How would this influence our understanding of the world?
