What is Chomsky's theory?
American-born linguist Noam Chomsky believes that we are born with a predisposition to learn language.
The essence of his theories of language acquisition state that human beings are pre-wired to learn language and in fact are born with the basic rules for language intact.The Chomsky Hierarchy correlates each class of languages to a specific type of automaton that can recognize it.
Examples include using deterministic finite automata (DFAs) for recognizing regular languages (Type 3 grammars) and using pushdown automata for identifying context-free languages (Type 2 grammars).
What is the Chomsky hierarchy?
To begin with, formal languages are organized into a nested hierarchy of increasing complexity.
In its classical formulation [3], this so-called Chomsky hierarchy has four levels of increasing complexity: regular, context-free, context-sensitive and computably enumerable languages.
What is the Chomsky rule?
Chomsky's rule for relating active and passive sentences (as given in Syntactic Structures) is very similar, at first sight, to Harris's, discussed above.
Chomsky's rule is: This rule, called the passive transformation, presupposes and depends upon the prior application of a set of phrase-structure rules.
