Language

[specifically verbal] is often confused with "communicating" which is nearly impossible. Language is a process whereby thoughts (term used loosely) are converted to exhalations over two thin and flapping membranes (vocal chords). The pitch created by the vibrations are shaped by the throat, tongue and 2 more flapping membranes (lips) and are then released into the immediate environment.

These modified vibrations will occasionally enter the ear canal of a nearby person where they are focused onto a tiny membrane (which doesn't quite "flap"). These vibrations are then sent to the brain where they are translated once again into thoughts.

The overhead and multiple translations so muddles the initial "thought" that [verbal] language is almost never used for important thoughts. However it is excellent for starting fights(see 'fighting' below).
