A word is a tag for something in our world that allows us to share with others what we and others see, hear, feel or otherwise experience in our real or imaged experiences. The symbolic meaning/s are then added to the tag word for said experience and are also shared by more words.
Before agriculture it was impossible for groups of humans to live in large numbers together. As hunter and gathers human group sizes remained small. So small that it was possible for everyone in the group to know each other person by relationships, name and status. As population increased a family or group of close friends would move out of the original group and create a new group, which over time drifts away from the founding body in important ways eventually including language and the words and their meanings.
For example, the hundreds of American Indian tribes shared many everyday life ways and traditions as well as spiritual traditions, but over time each eventually evolved in subtle ways which given more time began to be felt as important distinctions by the members of the different tribal groups. Eventually many different languages evolved over time which hastened the move towards an isolation from each other to varying degrees and consequences.
Even in monotheism which came about after the invention of agriculture and large scale societies this kind of moving apart has occurred over and over again and has often let to outright demonizing of one group by another a la the Religious Wars of Europe which were waged in the 16th, 17th and early 18th centuries. The conflicts of the Thirty Years’ War (1618-1648) culminated in the devastation of Germany and killed one-third of its population.
And so it has been in the past, let it no longer be in our present and future.
