It is patently obvious when YOU THINK about it, BUT I am not sure how many of us have ever given it any thought.
Babies, worldwide, when born are NOT ‘programmed’ (or predisposed) to speak any particular language. As long as they are ‘normal’ they will pick-up & learn whatever TONGUE they are most exposed to, i.e., the so called ‘mother tongue’.
I, as you should be able to tell, am NOT good at languages. I listen to Chinese or Russian & am CONVINCED that I would never have been able to master such languages. But, IF I had grown up being exposed to one of those languages it would have become my mother tongue. WOW.
You have to think about this. Quite neat when you finally get you mind around all of it.
No baby is born to speak English, Swahili, Sinhalese, Italian, Russian, Vietnamese or whatever.
Babies are born language-neutral.
