Explanation:

Its real simple think of it like this you are trying to learn how to skate you got to learn how to pedal then ollie then you can do your kickflip you cant just start off and immediately learn how to do a kickflip that is a recipe for failure and learning your mother tongue is just like learning the basics. You cant learn to say all of these big words in another language without learning it in your mother language our brains are hardwired that way.
