Transformational grammar
Deep structure and surface structure
According to the Syntactic structure published by Noam Chomsky, in language each
sentence possess two types of representation, namely, deep structure as well as surface structure
Deep structure is found to represent the core semantic relation of a sentence and hence is mapped
on the surface structure via transformation. Transformation can be proposed before the concept
of the unfathomable configuration as a mean of enhancing the numerical as well as expressive
power of the context free grammar. Likewise, profound construction has been made for
methodological reason associated to the early semantic theory.
Development of basic concepts
With time Chomsky abandoned the theory of deep and surface structure. However,
transformation continued to be a crucial part of his current theories. According his new theory of
Minimalism, Deep as well as surface structure has lost its eminence and both LF and PF
remained as the only representation level. The meaning of both profound construction and plane
construction has got changed over a number of times. While initially, D-structure used to
determine the meaning of a sentence, later LF took over the role.
Innate linguistic knowledge
Noam Chomsky had made it clear that transformational grammar is not intended for the
process through which human mind understands as well as construct sentences. According to
him, generative sentence structure only demonstrate the knowledge which underlies the ability of
the human too speak as well as understand. Majority of the knowledge is innate. Chomsky

further helped to make the theory of innateness respectable significantly by making concrete as
well as technologically sophisticated proposals about the language structure along with making
crucial proposals about how the accomplishment of grammatical theories can be evaluated.
According to Chomsky, there is no necessity to make n infant learn about any actual rule which
is explicit to a specific language at all. Instead, all the languages follow a specific set of rules.
However, the effect of the mentioned rules along with the connections between them has the
potential to vary on the basis of the values of specific linguistic parameters. Being a highly
sturdy supposition, the mentioned theory is considered to be one of the most unique theories of
language.
Grammatical theories
Chomsky, in the year 1960, introduced two central ideas associated with construction as
well as evaluation of the grammatical theory. The first idea pointed out the difference between
competence and performance. According to him, the errors made by individuals during speaking
are irrelevant to the linguistic competence. When it comes to the second idea, it is directly
associated with the evaluation of the theories of grammar. Chomsky is found to be made a
difference between grammar that attained descriptive adequacy as well as grammar that attains
explanatory adequacy. According to the theory, the grammar that achieves explanatory adequacy
posses the property of providing an insight into the linguistic structure underlying the human
mind. He explained that the explanatory adequacy of the grammatical theory enable it to explain
any type of grammatical nuances of the language of the world. According to him, progress in
term of descriptive adequacy will only come only if explanatory adequacy is considered to be the
goal. According to the Chomsky, real insight into the structure of the individual languages can
only be gained with the help of comparative study of a wide variety of languages.
