What is language?

Here are some different statements about language:

- "Language surrounds us every day and we know how to recognise it" 

 

- "A word is one or more sounds that in combination have a specific meaning assigned by the language"

 

- "The most powerful tool known is the one we use to build every other tool"

I think that the statements are all true because language is a very important tool that let us all communicate, and without communication, the problem in the story of the tower of Babel  will happen to us.
