There is abundant evidence that the best time to learn a new language is relatively early in life. We are born with greater brain capacity than we actually realize, which is why children pick up a second language so easily. The optimum window of opportunity for learning languages lasts until about the age of nine to twelve, yet most U.S. school districts wait until Junior High or even High School — after the ‘window’ is closed.
If you wait, it might be too late!
Learning a language later in life doesn’t quite become impossible. It just becomes a lot more difficult! But all the intellectual benefits of early learning are lost. And the ease that nature intended to accompany the young’s acquisition of language will be gone ~forever~.
