Language

Explanation:

A language is a system that is a combination of arbitrary symbols that can produce an infinite number of meaningful statements. Language defined by the Britannica Encyclopedia is “a system of conventional spoken or written symbols that has meaning to the participants of a specific culture”. As stated before, we use different symbols to create a word that means something to us. Each symbol has each own pronunciation as well as each word. The most interesting part is that each language is very different from each other. There are other symbols and other meanings to words. In conclusion, we can state that with language we have an infinite form of communication; we just need to learn the rules of each language.
