Text is a way to communicate without having to speak. It is just as explanatory as speaking and can, in some ways, say more than a person could say. Text is any form of writing that was created for a purpose whether it is to inform, to teach, or to explain. Text serves as a means of communication when talking isn't necessarily an option, i.e. text messaging. Just about everyone texts now because of its convenience and how much quicker it is than it would be to call someone. Think about how much easier it is in some cases to text people, you accomplish the same thing but in less time and effort. Therefore, text is more or less, communication  redefined.
