Language

A language is a system of arbitrary signals, such as voice sounds, gestures or written symbols which communicate thoughts or feelings.Human spoken and written languages can be described as a system of symbols and the grammars by which the symbols are manipulated. The word "language" is also used to refer to common properties of languages and to communicate to other person.

Language learning is normal in human childhood. Most human languages use patterns of sound or gesture for symbols which enable communication with others around them. There are thousands of human languages, and these seem to share certain properties,feelings even though many shared properties have exceptions.

There is no defined line between a language and a dialougue, but Max Weinreich is credited as saying that "a language is a dialect with an army and a navy;" in other words, the distinction between a language and a dialect of a language is as much due to political divisions as it is because of cultural differences, distinctive writing systems, or mutual intelligibility.
