What is language?

We define language being word use and sentence structure, as well as what's commonly spoken in your region-- Be it dialect or diction. It could be defined as a pattern, symbols and sounds that let us speak and get our ideas out. Languages are languages no matter what, if it were a made up language that only you know it is a language. If it's a language nobody speaks, it is a language. Words are merely sounds and patterns put together to create words and sentences, therefore a language, letters and words will always make up a way to communicate.
