Languages are often considered as a standard mode of communication. There are standard definitions for each word defined authoritative institutions, there are standard tests that test for these standard language skills as they are defined.

But like most things, the theory and practice differ in nature.

The theoretical and practical languages have their intersections.

But the practical usage of language differs in wide ways across the population which speaks it. This is the meta nature of all languages.

Languages even though look like generic protocols of information exchange, are very much individualistic in their nature. Even the popular ones. The individualization of a theoretical language starts from a very early stage. Over time as our experiences with our surrounding conversations evolve the same words start to change their meaning, their underlying emotion, and their interpretation by the audience.

The two communicating parties have subtle but important differences in how their biological neural net interprets the same exact words. The interpretation changes with context, location, situation, accent & dialect.

This makes communication an art & language meta in nature.
