* Language is constantly evolving: Words develop and change over time. It's highly unlikely that anyone consciously "invented" the word "no". Instead, it likely arose from sounds or gestures used to express negation, gradually evolving into the word we know today.
* Early languages are poorly documented: Our understanding of ancient languages is often based on fragments and reconstructions. We don't have clear records of the earliest stages of language development, including the origins of "no".
* "No" exists in many forms: The word "no" exists in various forms across languages, suggesting a very old and widespread concept.
Instead of a specific date, we can say:
* "No" likely has roots in very early human language: Our ancestors likely used sounds or gestures to express refusal or negation long before written language existed.
* The concept of negation is universal: Across cultures and languages, humans have ways to express "no". This suggests a deep-rooted human need for this concept.
While we can't pinpoint the exact invention of "no", we can appreciate its long and fascinating history within the evolution of human language.
