Variable (mathematics)
In mathematics, a variable (from Latin language, Latin ) is a Mathematical symbol, symbol, typically a letter, that refers to an unspecified mathematical object. One says colloquially that the variable ''represents'' or ''denotes'' the object, and that any valid candidate for the object is the value (mathematics), value of the variable. The values a variable can take are usually of the same kind, often numbers. More specifically, the values involved may form a Set (mathematics), set, such as the set of real numbers. The object may not always exist, or it might be uncertain whether any valid candidate exists or not. For example, one could represent two integers by the variables and and require that the value of the square of is twice the square of , which in algebraic notation can be written . A definitive proof that this relationship is impossible to satisfy when and are restricted to integer numbers isn't obvious, but it has been known since ancient times and has had a big ...

Bare Phrase Structure
In linguistics, the minimalist program is a major line of inquiry that has been developing inside generative grammar since the early 1990s, starting with a 1993 paper by Noam Chomsky. Following Imre Lakatos's distinction, Chomsky presents minimalism as a program, understood as a mode of inquiry that provides a conceptual framework which guides the development of linguistic theory. As such, it is characterized by a broad and diverse range of research directions. For Chomsky, there are two basic minimalist questions—What is language? and Why does it have the properties it has?—but the answers to these two questions can be framed in any theory.Boeckx, Cedric ''Linguistic Minimalism. Origins, Concepts, Methods and Aims'', pp. 84 and 115. Conceptual framework Goals and assumptions Minimalism is an approach developed with the goal of understanding the nature of language. It models a speaker's knowledge of language as a computational system with one basic operation, namely Me ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lexical-functional Grammar
Lexical functional grammar (LFG) is a constraint-based grammar framework in theoretical linguistics. It posits several parallel levels of syntactic structure, including a phrase structure grammar representation of word order and constituency, and a representation of grammatical functions such as subject and object, similar to dependency grammar. The development of the theory was initiated by Joan Bresnan and Ronald Kaplan in the 1970s, in reaction to the theory of transformational grammar which was current in the late 1970s. It mainly focuses on syntax, including its relation with morphology and semantics. There has been little LFG work on phonology (although ideas from optimality theory have recently been popular in LFG research). Some recent work combines LFG with Distributed Morphology in Lexical-Realizational Functional Grammar.Ash Asudeh, Paul B. Melchin & Daniel Siddiqi (2021).

Verb Phrase
In linguistics, a verb phrase (VP) is a syntax, syntactic unit composed of a verb and its argument (linguistics), arguments except the subject (grammar), subject of an independent clause or coordinate clause. Thus, in the sentence ''A fat man quickly put the money into the box'', the words ''quickly put the money into the box'' constitute a verb phrase; it consists of the verb ''put'' and its arguments, but not the subject ''a fat man''. A verb phrase is similar to what is considered a ''predicate (grammar), predicate'' in traditional grammars. Verb phrases generally are divided among two types: finite, of which the Head (linguistics), head of the phrase is a finite verb; and nonfinite, where the head is a nonfinite verb, such as an infinitive, participle or gerund. Phrase structure grammars acknowledge both types, but dependency grammars treat the subject as just another verbal dependent, and they do not recognize the finite verbal phrase constituent (linguistics), constituent.

Noam Chomsky
Avram Noam Chomsky (born December 7, 1928) is an American professor and public intellectual known for his work in linguistics, political activism, and social criticism. Sometimes called "the father of modern linguistics", Chomsky is also a major figure in analytic philosophy and one of the founders of the field of cognitive science. He is a laureate professor of linguistics at the University of Arizona and an institute professor emeritus at the Massachusetts Institute of Technology (MIT). Among the most cited living authors, Chomsky has written more than 150 books on topics such as linguistics, war, and politics. In addition to his work in linguistics, since the 1960s Chomsky has been an influential voice on the American Left, American left as a consistent critic of U.S. foreign policy, Criticism of capitalism, contemporary capitalism, and Corporate influence on politics in the United States, corporate influence on political institutions and the media.

Zellig Harris
Zellig Sabbettai Harris (; October 23, 1909 – May 22, 1992) was an influential American linguist, mathematical syntactician, and methodologist of science. Originally a Semiticist, he is best known for his work in structural linguistics and discourse analysis and for the discovery of transformational structure in language. These developments from the first 10 years of his career were published within the first 25. His contributions in the subsequent 35 years of his career include transfer grammar, string analysis ( adjunction grammar), elementary sentence-differences (and decomposition lattices), algebraic structures in language, operator grammar, sublanguage grammar, a theory of linguistic information, and a principled account of the nature and origin of language. Biography Harris was born on October 23, 1909, in Balta, in the Podolia Governorate of the Russian Empire (present-day Ukraine). He was Jewish. In 1913 when he was four years old his family immigrated to Philadelph ... [...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 ...

Endocentric Structure
In theoretical linguistics, a distinction is made between endocentric and exocentric constructions. A grammatical construction (for instance, a phrase or compound) is said to be ''endocentric'' if it fulfils the same linguistic function as one of its parts, and ''exocentric'' if it does not. The distinction reaches back at least to Bloomfield's work of the 1930s, who based it on terms by Pāṇini and Patañjali in Sanskrit grammar. Such a distinction is possible only in phrase structure grammars (constituency grammars), since in dependency grammars all constructions are necessarily endocentric. Endocentric construction An endocentric construction consists of an obligatory head and one or more dependents, whose presence serves to modify the meaning of the head. For example: # sub>NP [A big[N house">lt;sub>A<_sub>_big.html" ;"title="sub>NP [A big">sub>NP [A big[N house #[VP [V sing] [N songs #[AP [Adv very] [A long These phrases are indisputably endocentric. They are end ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Poverty Of The Stimulus
In linguistics, the poverty of the stimulus is the claim that children are not exposed to rich enough data within their linguistic environments to acquire every feature of their language without innate language-specific cognitive biases. Arguments from the poverty of the stimulus are used as evidence for universal grammar, the notion that at least some aspects of linguistic competence are innate. The term "poverty of the stimulus" was coined by Noam Chomsky in 1980. A variety of linguistic phenomena have been used to argue for universal grammar on the basis that children do not have sufficient evidence to acquire the phenomena using general (i.e., non-language-specific) cognition alone. Critics of the universal grammar hypothesis have proposed alternative models that suggest acquisition of these phenomena may be less difficult than has been previously claimed. The empirical and conceptual bases of poverty of the stimulus arguments are a topic of continuing debate in linguistics. ...
