The ideal age to learn second or third language is approximately until the age of 3. From 3 to 8 is the second best moment, because the window of opportunity is still open. The most appropriate route, according to experts, is that language learning in childhood happens during the games. 3 years is the ideal age because it is at this age that the neural pathways not associated with the mother tongue of a child begin to disappear.
The linguistic interaction in which the child participates provides most of the data in this process of cognitive development. As a consequence, the neural structures in the brain that correspond to the concepts that are being learned end up naturally and closely associated with the neural structures that correspond to the forms of the language.
