The terminal yield of a surface structure tree, the surface form, is then predicted to be a grammatical sentence of the language being studied. The role and significance of deep structure changed a great deal as Chomsky developed his theories, and since the mid-1990s deep structure no longer features at all [6] (see minimalist program).
In transformational grammar, each sentence in a language has two levels of representation: a deep structure and a surface structure. [3] The deep structure represents a sentence's core semantic relations and is mapped onto the surface structure, which follows the sentence's phonological system very closely, via transformations. Deep structures ...
The base, in turn, consists of a categorial subcomponent and a lexicon. The base generates deep structures. A deep structure enters the semantic component and receives a semantic interpretation; it is mapped by transformational rules into a surface structure, which is then given a phonetic interpretation by the rules of the phonological component."
"A sentence has an inner mental aspect (a deep structure that conveys its meaning) and an outer, physical aspect as a sound sequence." [citation needed] Chomsky claims that Port Royal linguists developed a theory of deep and surface structures that meets the formal requirements of language theory.
In linguistics, transformational syntax is a derivational approach to syntax that developed from the extended standard theory of generative grammar originally proposed by Noam Chomsky in his books Syntactic Structures and Aspects of the Theory of Syntax. [1] It emerged from a need to improve on approaches to grammar in structural linguistics.
In transformational grammar, rules called transformations mapped a level of representation called deep structures to another level of representation called surface structure. The semantic interpretation of a sentence was represented by its deep structure, while the surface structure provided its pronunciation.
Syntactic Structures is an important work in linguistics by American linguist Noam Chomsky, originally published in 1957.A short monograph of about a hundred pages, it is recognized as one of the most significant and influential linguistic studies of the 20th century.
the elimination of the distinction between deep structure and surface structure in favour of a derivational approach; the elimination of X-bar theory in favour of bare phrase structure (see below) the elimination of indexation in favour of Move or Agree; the elimination of the notion of government in favour of feature-checking
