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 ...
For example, an active sentence such as "The doctor examined the patient" and "The patient was examined by the doctor", had the same deep structure. The difference in surface structures arises from the application of the passivization transformation, which was assumed to not affect meaning.
A core aspect of the original Standard Theory is a distinction between two different representations of a sentence, called deep structure and surface structure. The two representations are linked to each other by a set of transformation rules, the totality of these rules is what constitute grammar, and what a grammatical description of a ...
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."
The term wh-movement stemmed from early generative grammar in the 1960s and 1970s and was a reference to the theory of transformational grammar, in which the interrogative expression always appears in its canonical position in the deep structure of a sentence but can move leftward from that position to the front of the sentence/clause in the ...
To account for oblique datives, Larson adopts a proposal originally made by Chomsky (1955, 1975), where the verb in the deep structure is raised in the surface structure (S-structure) (see Figure 1).

The structural forms generated by P-rules alone were said to constitute deep structure. Surface structure was then derived transformationally by T-rules from the kernel structures first generated by the operation of P-rules. In this way, Chomsky proposed to generate an infinite number of sentences using finite means (the closed sets of P-rules ...
