To start off, the actual definition of Language is Communication of thoughts and feelings through a system of arbitrary signals, such as voice sounds, gestures, or written symbols. But what is your definition? What is mine? We all have such different minds, so if you asked a sample of people this same question you would get a multitude of answers.
You may want to know where I'm going with this. The big point is that language is the starting point of everything. We cannot talk without language, cannot write without language, and certainly cannot communicate with the world around us without language.
The important thing to know about language is that every culture has their own. Here in NH, the majority of us speak some form of English, but a few towns over in Lawrence, MA the primary language is Spanish, crazy right?
This leads me to talk about my favorite topic of all, BOOKS!
Translation services like Smartling help provide an opportunity for people to read the same books all over the world in their language.
