What is Language?

Language.... what can I say? 

Language is everything for me! It is what allows me to interact with other people, what allows me to know and be part of a culture, Language is a group of organized signs, like Chomsky says Language is a system of phonology, syntax, and semantics, but it is a means of functioning in the society Halliday(1973). 

Language is everything around us, language is power, language is a cultural device, language is the most beautiful ability, possession and instrument that human beings have. 

As well, for Vivian Cook (1940) a professor of Applied Linguistics at Newcastle University in the United Kingdom, Language is a human representation, an external entity, a set of sentences, a shared possession of a community, a mental system, a form of action, so there is not just one definition about what language is! for this reason we cannot give a strict concept about Language, we just can enjoy this gift that has been given to all of us, and use it to do of this world a better place to LIVE!
