on the native qualities

[Georges Adassovsky]

Dear Tsuji!
In the following, I am using the word "language" for the language in
general, and the word "tongue" for a specific language (Russian Japanese,
English, etc...) In French we have two distinct words.
You are focussing on the process of teaching, and seem to forget the
process of learning. Children are physiologically and neurologically opened
to learning in general, and to language acquisition in particular. Brains
disposition to language acquisition is over at the age of six or eight.
I don't beleive methods instinctively used to teach language to a child are
applyable to adults learning a tongue.
A child acquires the ability to use a language, that is he completes his
neurologic formation, and at the same time, he acquires the command of a
given tongue.
A specific tongue acquired at the same time as the ability to use a
language caracterizes "native tongue".
These "native tongues" may be one, two, or three, depending on the fact
they have been acquired at the time when brains were opened to language
acquisition.

Best,
Georges.
