Empty Category Principle
In linguistics, the empty category principle (ECP) was proposed in Noam Chomsky's syntactic framework of government and binding theory. The ECP is supposed to be a universal syntactic constraint that requires certain types of empty categories, namely traces, to be properly governed. ECP is a principle of transformational grammar by which traces must be visible, i.e. they must be identifiable as empty positions in the surface structure, similar to the principle of reconstruction for deletion. Thus an empty category is in a position subcategorized for by a verb. In government and binding theory this is known as ''proper government''. Proper government occurs either if the empty position is governed by a lexical category (especially if it is not a subject) (theta-government) or if it is coindexed with a maximal projection which governs it (antecedent-government). The ECP has been revised many times and is now a central part of government and binding theory. In spite of its name, th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Linguistics
Linguistics is the scientific study of language. The areas of linguistic analysis are syntax (rules governing the structure of sentences), semantics (meaning), Morphology (linguistics), morphology (structure of words), phonetics (speech sounds and equivalent gestures in sign languages), phonology (the abstract sound system of a particular language, and analogous systems of sign languages), and pragmatics (how the context of use contributes to meaning). Subdisciplines such as biolinguistics (the study of the biological variables and evolution of language) and psycholinguistics (the study of psychological factors in human language) bridge many of these divisions. Linguistics encompasses Outline of linguistics, many branches and subfields that span both theoretical and practical applications. Theoretical linguistics is concerned with understanding the universal grammar, universal and Philosophy of language#Nature of language, fundamental nature of language and developing a general ...

Move α
Move α is a feature of many transformational-generative grammars, first developed in the Revised Extended Standard Theory (REST) by Noam Chomsky in the late 1970s and later part of government and binding theory (GB) in the 1980s and the Minimalist Program of the 1990s. The term refers to the relation between an indexed constituent and its trace ''t'', e.g., the relation of ''whom'' and ''t'' in the example :(1) Whomi do you think you are kidding ti? In (1), the constituent (''whom'') and its trace (''t'') are said to form a "chain". In syntax, Move α is the most general formulation of possible movement permitted by a rule. More specific rules include Move NP and Move wh, which in turn are more general than specific transformations such as those involved in passivization. This marks a shift of attention in transformational grammar around the 1970s, away from focussing on specific rules to underlying principles constraining them, which culminated into the development of the ...

Complementizer
In linguistics (especially generative grammar), a complementizer or complementiser (list of glossing abbreviations, glossing abbreviation: ) is a functional category (part of speech) that includes those words that can be used to turn a clause into the subject (grammar), subject or object (grammar), object of a sentence (linguistics), sentence. For example, the word ''that'' may be called a complementizer in English language, English sentences like ''Mary believes that it is raining''. The concept of complementizers is specific to certain modern grammatical theories. In traditional grammar, such words are normally considered conjunction (grammar), conjunctions. The standard abbreviation for ''complementizer'' is C. Category of C C as head of CP The complementizer is often held to be the syntactic head (linguistics), head of a full clause, which is therefore often represented by the abbreviation CP (for ''complementizer phrase''). Evidence of the complementizer functioning as the h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Logical Form
In logic, the logical form of a statement is a precisely specified semantic version of that statement in a formal system. Informally, the logical form attempts to formalize a possibly ambiguous statement into a statement with a precise, unambiguous logical interpretation with respect to a formal system. In an ideal formal language, the meaning of a logical form can be determined unambiguously from syntax alone. Logical forms are semantic, not syntactic constructs; therefore, there may be more than one string that represents the same logical form in a given language. The logical form of an argument is called the argument form of the argument. History The importance of the concept of form to logic was already recognized in ancient times. Aristotle, in the '' Prior Analytics'', was one of the first people to employ variable letters to represent valid inferences. Therefore, Jan Łukasiewicz claims that the introduction of variables was "one of Aristotle's greatest inventions." ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
C-command
In generative grammar and related frameworks, a node in a parse tree c-commands its sister node and all of its sister's descendants. In these frameworks, c-command plays a central role in defining and constraining operations such as syntactic movement, Binding (linguistics), binding, and scope (formal semantics), scope. Tanya Reinhart introduced c-command in 1976 as a key component of her theory of Anaphora (linguistics), anaphora. The term is short for "Constituent (linguistics), constituent command". Definition and examples Standard Definition Common terms to represent the relationships between nodes are below (refer to the tree on the right): *M is a parent or mother to A and B. *A and B are children or daughters of M. *A and B are sisters or siblings. *M is a grandparent or grandmother to C and D. The standard definition of c-command is based partly on the relationship of dominance: ''Node N1 dominates node N2 if N1 is above N2 in the tree and one can trace a path from N1 ...

Matrix Clause
In language, a clause is a Constituent (linguistics), constituent or Phrase (grammar), phrase that comprises a semantic predicand (expressed or not) and a semantic Predicate (grammar), predicate. A typical clause consists of a subject (grammar), subject and a syntactic Predicate (grammar), predicate, the latter typically a verb phrase composed of a verb with or without any object (grammar), objects and other Grammatical modifier, modifiers. However, the subject is sometimes unexpressed if it is easily deducible from the context, especially in null-subject languages but also in other languages, including instances of the imperative mood in English grammar, English. A complete simple sentence contains a single clause with a finite verb. Complex sentences contain at least one clause subordinated (dependent clause, ''dependent'') to an ''independent clause'' (one that could stand alone as a simple sentence), which may be co-ordinated with other independents with or without dependents. ...

Wh-movement
In linguistics, wh-movement (also known as wh-fronting, wh-extraction, or wh-raising) is the formation of syntactic dependencies involving interrogative words. An example in English is the dependency formed between ''what'' and the object position of ''doing'' in "What are you doing?". Interrogative forms are sometimes known within English linguistics as '' wh-words'', such as ''what, when, where, who'', and ''why'', but also include other interrogative words, such as ''how''. This dependency has been used as a diagnostic tool in syntactic studies as it can be observed to interact with other grammatical constraints. In languages with wh- movement, sentences or clauses with a wh-word show a non-canonical word order that places the wh-word (or phrase containing the wh-word) at or near the front of the sentence or clause ("''Whom'' are you thinking about?") instead of the canonical position later in the sentence ("I am thinking about ''you''"). Leaving the wh-word in its canonical pos ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Theta Role
Theta roles are the names of the participant roles associated with a predicate: the predicate may be a verb, an adjective, a preposition, or a noun. If an object is in motion or in a steady state as the speakers perceives the state, or it is the topic of discussion, it is called a theme. The participant is usually said to be an argument of the predicate. In generative grammar, a theta role or θ-role is the formal device for representing syntactic argument structure—the number and type of noun phrases—required syntactically by a particular verb. For example, the verb ''put'' requires three arguments (i.e., it is trivalent). The formal mechanism for implementing a verb's argument structure is codified as theta roles. The verb ''put'' is said to "assign" three theta roles. This is coded in a theta grid associated with the lexical entry for the verb. The correspondence between the theta grid and the actual sentence is accomplished by means of a bijective filter on the grammar k ...

If And Only If
In logic and related fields such as mathematics and philosophy, "if and only if" (often shortened as "iff") is paraphrased by the biconditional, a logical connective between statements. The biconditional is true in two cases, where either both statements are true or both are false. The connective is biconditional (a statement of material equivalence), and can be likened to the standard material conditional ("only if", equal to "if ... then") combined with its reverse ("if"); hence the name. The result is that the truth of either one of the connected statements requires the truth of the other (i.e. either both statements are true, or both are false), though it is controversial whether the connective thus defined is properly rendered by the English "if and only if"—with its pre-existing meaning. For example, ''P if and only if Q'' means that ''P'' is true whenever ''Q'' is true, and the only case in which ''P'' is true is if ''Q'' is also true, whereas in the case of ''P if Q ...
