The extended projection principle (EPP) is a linguistic hypothesis about subjects.It was proposed by Noam Chomsky as an addendum to the projection principle. [1] The basic idea of the EPP is that clauses must contain a noun phrase or determiner phrase in the subject position (i.e. in the specifier of a tense phrase or inflectional phrase or in the specifier of a verb phrase in languages in ...
The Extended Projection Principle (EPP) refers to the highest Tense Phrase containing a subject. [6] Before the EPP can be satisfied, you must ensure that LOS is satisfied. Once all of the projection principles of LOS are satisfied, EPP is activated when there is movement from one part of the tree to another.
The projection principle requires that lexical properties — in particular argument structure properties such as thematic roles — be "projected" onto syntactic structures. Together with Locality of Selection, which forces lexical properties to be projected within a local projection (as defined by X-bar theory [ 1 ] : 149 ), the projection ...
The "EPP" notation stands for "extended projection principle" feature, NOM stands for "nominative case".) Tense first merges with a V-projection, and the output then combines the DP subject the girl, which, in some sense, merges twice: once within the V-projection, and once within the T-projection. (See discussion of Move below.)
Extended Projection Principle states that all clauses must contain a DP subject and Case Theory states that all DP's must check for Case in the complement or specifier position. A theta role is not assigned to the subject position because the subject is underlyingly in the object position during theta role assignment (which happens in the d ...
In the wh-movement, there are additional segments that are added: EPP (extended projection principle) and the Question Feature [+Q] that represents a question sentence. The wh-movement is motivated by a Question Feature/EPP at C (Complementizer), which promotes movement of a wh-word from the canonical base position to Spec-C.
Principles and parameters is a framework within generative linguistics in which the syntax of a natural language is described in accordance with general principles (i.e. abstract rules or grammars) and specific parameters (i.e. markers, switches) that for particular languages are either turned on or off.
The theta-criterion (also named θ-criterion) is a constraint on x-bar theory that was first proposed by Noam Chomsky () as a rule within the system of principles of the government and binding theory, called theta-theory (θ-theory).
