    Noam Chomsky
        FATHER OF MODERN
           LINGUISTICS
                HE CLAIMS
  Children are biologically programmed for
 language and that language develops in the
child in just the same way that other biological
              functions develop.
  Chomsky proposed the existence of a Language
  Acquisition Device (LAD), or Universal Grammar
(UG) as it has been more recently called, as the key
to language learning. According to him, nature has
endowed all human beings with special mechanism
  in the brain, and it is which helps children know
                the rules of language.
          Black Box
THE LAD WAS   OFTEN DESCRIBED AS AN IMAGINARY
'BLACK BOX’ WHICH EXISTS SOMEWHERE IN THE
BRAIN. THIS ‘BLACK BOX’ THOUGHT TO CONTAIN ALL
AND ONLY THE PRINCIPLES WHICH
ARE UNIVERSAL TO ALL HUMAN LANGUAGES,
PREVENTS THE CHILD FROM GOING OFF ON LOTS
OF THE LANGUAGE. FOR THE LAD TO WORK, THE
CHILD NEEDS ACCESS ONLY TO SAMPLES OF
A NATURAL LANGUAGE. THESE LANGUAGE SAMPLES
SERVE AS A TRIGGER TO ACTIVATE THE
DEVICE.
McNeill (1966) described LAD
as consisting of four innate
linguistic properties:
       THE ABILITY TO DISTINGUISH   KNOWLEDGE THAT ONLY A
       SPEECH SOUNDS FROM OTHER     CERTAIN KIND OF LINGUISTIC
       SOUNDS IN THE                SYSTEM IS POSSIBLE AND
       ENVIRONMENT;                 THAT
                                    OTHER KINDS ARE NOT;
       THE ABILITY TO ORGANIZE      THE ABILITY TO ENGAGE IN CONSTANT
                                    EVALUATION OF THE DEVELOPING
       LINGUISTIC DATA INTO
                                    LINGUISTIC SYSTEM SO AS TO
       VARIOUS CLASSES THAT CAN     CONSTRUCT THE SIMPLEST POSSIBLE
       LATER BE                     SYSTEM OUT OF THE AVAILABLE
       REFORMED;                    LINGUISTIC
                                    INPUT.
