Language? There is more more to it then you think! Human language is unique in being a symbolic communication system that is learned instead of biologically inherited..A word or symbol are sounds or things which have meaning given to them by the users. For example when you say dog you think of a furry, four legged animal with a wagging tail. Now think of these word, canis, perro, chien, or hund. What do you make of them? They are all actually words for dogs in European language. This shows that in diff. parts of the world, language and symbols varies in meaning and interpretation.

When something is said the meanings depend on where and when it is used.
Language is and will constantly evolve as time pass by. Language change in response of social and historical conditions. For example, the English word "nice" now generally means pleasing, agreeable, polite, and kind. In the15th century it meant foolish, wanton, lascivious, and even wicked.

Now if you language think have no rules you're wrong! Language is the set of rules for generating speech (Speech and Language NOT the same thing).Language is actually govern by a few rules, phonological rules (how you pronounce something, which is not taught to us but we are definitely following them sub-consciously ), syntatic rules ( is how a sentence is structure, in diff language a sentence structure can be diff. even if it means the same thing), semantic rules and pragmatic rules.

Just a short look at the human brain. Many studies have been done to learn more about part of the brain that controls speech and language. Though these studies were only conducted after many realises that several people have communications problem.

Research done by Marc Dax in 1836 shows that patients with damage to Broca’s area located at the left frontal cortex can understand language, they generally are unable to produce speech because words are not formed properly, thus slurring their speech.

In 1876, Carl Wernicke discovered that language problems also could result from damage to another section of the brain which is ‘Wernicke’s area’ located in the posterior part of the temporal lobe . Damage to Wernicke’s area results in a loss of the ability to understand language. Thus, patients can continue to speak, but the words are put together in such a way that they make no sense.

Interestingly, in most people (approximately 97%) both Broca’s area and Wernicke’s area are found only in the left hemisphere, which explains the language deficits observed in patients with brain damage to the left side of the brain.

Language is a powerful tool and one should never under estimate it's ability. Language can and will reflect many things about a person. Language reflects ones power and affliliation whether you can converge or diverge when in diff social groups. Besides that it reflects your interest and attraction towards something. Also how you use language can reflect how responsible you are as a person in any kind of situations.

Done.
