Why do you think Language was originated?In my opinion language was created to communicate.Today people study grammar.I believe there is No point of grammar if you can communicate with the other people as long as they understand you.If the other person knows what typing,you don't have to put capital letters or commas.If the other person actually dosn't understand you then you use grammar.There is no point in learning grammar if the people around you can know what you're saying.There is so many languages and dialects in the world that you cannot learn all of them.
