We should not forget that it can behave like a virus. Some may go as far to say that it is one.
Supposedly it is used to encode and decode information by using arbitrary symbols and sounds.
The development and usage of language is a credit to the human (and inhuman.. un-human) creativity.
We’re taught rules of our native tongue when young so we can effectively communicate to others of similar descent or culture. Learned so young, language becomes innate, often inseparable from what we term our thoughts. Words, concepts and ideas have become interchangeable. The structure of language steers our perceptions.
Mediums are used to convey expression primarily. While some may attest that language was developed to facilitate reason, the expression inherently imbued in the use of language creates a much denser medium.
Much of language, as it presents itself, is not transparent. Even “honesty,” which strives for transparency, manifests as translucent at best.
It is naive to limit one’s view of language to merely words. Words can act as cloaks, masks, decoys. There are so many more communicative tools beyond the written or spoken words. Yes, I am talking of nonverbal communication such as body language, but also beyond that as well. Nuances, aires, scents… are all languages, illustrating similar properties when behaving as a vein of the Language entity.
As an egregore, composed of the whole of the human race (not to mention every life form on the planet… and potentially every astronomical and astral body), it is rapidly evolving, acutely aware, constantly shifting and highly adaptable and evasive.
It’s really not about what you say, or how you say it. It’s not even about if you “mean” it (or if you think you do, or if you don’t but you want to, etc). It’s about something completely different from all that… something that by virtue of its nature, I cannot put into words or ever convey to another.
