Generative Linguistics
Generative grammar is a research tradition in linguistics that aims to explain the cognition, cognitive basis of language by formulating and testing explicit models of humans' subconscious grammatical knowledge. Generative linguists, or generativists (), tend to share certain working assumptions such as the linguistic competence, competence–linguistic performance, performance distinction and the notion that some domain-specific aspects of grammar are partly innate in humans. These assumptions are rejected in non-generative approaches such as usage-based models of language. Generative linguistics includes work in core areas such as syntax, semantics, phonology, psycholinguistics, and language acquisition, with additional extensions to topics including biolinguistics and music cognition. Generative grammar began in the late 1950s with the work of Noam Chomsky, having roots in earlier approaches such as structural linguistics. The earliest version of Chomsky's model was calle ...

Government And Binding Theory
Government and binding (GB, GBT) is a theory of syntax and a phrase structure grammar in the tradition of transformational grammar developed principally by Noam Chomsky in the 1980s. This theory is a radical revision of his earlier theories and was later revised in '' The Minimalist Program'' (1995) and several subsequent papers, the latest being ''Three Factors in Language Design'' (2005). Although there is a large literature on government and binding theory which is not written by Chomsky, Chomsky's papers have been foundational in setting the research agenda. The name refers to two central subtheories of the theory: ''government'', which is an abstract syntactic relation applicable, among other things, to the assignment of case; and '' binding'', which deals chiefly with the relationships between pronouns and the expressions with which they are co-referential. GB was the first theory to be based on the principles and parameters model of language, which also underlies the later ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Declarative Mood
A realis mood ( abbreviated ) is a grammatical mood which is used principally to indicate that something is a statement of fact; in other words, to express what the speaker considers to be a known state of affairs, as in declarative sentences. Most languages have a single realis mood called the indicative mood, although some languages have additional realis moods, for example to express different levels of certainty. By contrast, an irrealis mood is used to express something that is not known to be the case in reality. An example of the contrast between realis and irrealis moods is seen in the English sentences "He works" and "It is necessary that he work". In the first sentence, ''works'' is a present indicative (realis) form of the verb, and is used to make a direct assertion about the real world. In the second sentence, ''work'' is in the subjunctive mood, which is an irrealis mood – here ''that he work'' does not necessarily express a fact about the real world (he could ...

Future Tense
In grammar, a future tense ( abbreviated ) is a verb form that generally marks the event described by the verb as not having happened yet, but expected to happen in the future. An example of a future tense form is the French ''achètera'', meaning "will buy", derived from the verb ''acheter'' ("to buy"). The "future" expressed by the future tense usually means the future relative to the moment of speaking, although in contexts where relative tense is used it may mean the future relative to some other point in time under consideration. English does not have an inflectional future tense, though it has a variety of grammatical and lexical means for expressing future-related meanings. These include modal auxiliaries such as ''will'' and ''shall'' as well as the futurate present tense. Expressions The nature of the future, necessarily uncertain and at varying distances ahead, means that the speaker may refer to future events with the modality either of probability (what the sp ...

Tag Questions
A tag question is a construction in which an interrogative element is added to a declarative or an imperative clause. The resulting speech act comprises an assertion paired with a request for confirmation. For instance, the English tag question "You're John, aren't you?" consists of the declarative clause "You're John" and the interrogative tag "aren't you?" Uses In most languages, tag questions are more common in spoken usage than in formal written usage. They can be an indicator of politeness, hedging, consensus seeking, emphasis and irony. They may suggest confidence or lack of confidence; they may be confrontational, defensive or tentative. Although they have the grammatical form of a question, they may be rhetorical (not expecting an answer). In other cases, when they do expect a response, they may differ from straightforward questions in that they cue the listener as to what response is desired. In legal settings, tag questions can often be found in a leading question ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Imperative Mood
The imperative mood is a grammatical mood that forms a command or request. The imperative mood is used to demand or require that an action be performed. It is usually found only in the present tense, second person. They are sometimes called ''directives'', as they include a feature that encodes directive force, and another feature that encodes modality of unrealized interpretation. An example of a verb used in the imperative mood is the English phrase "Go." Such imperatives imply a second-person subject (''you''), but some other languages also have first- and third-person imperatives, with the meaning of "let's (do something)" or "let them (do something)" (the forms may alternatively be called cohortative and jussive). Imperative mood can be denoted by the glossing abbreviation . It is one of the irrealis moods. Formation Imperative mood is often expressed using special conjugated verb forms. Like other finite verb forms, imperatives often inflect for person and nu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Traditional Grammar
Traditional grammar (also known as classical grammar) is a framework for the description of the structure of a language or group of languages. The roots of traditional grammar are in the work of classical Greek and Latin philologists. The formal study of grammar based on these models became popular during the Renaissance. Traditional grammars may be contrasted with more modern theories of grammar in theoretical linguistics, which grew out of traditional descriptions. While traditional grammars seek to describe how particular languages are used, or to teach people to speak or read them, grammar frameworks in contemporary linguistics often seek to explain the nature of language knowledge and ability common to all languages. Traditional grammar is often prescriptive, and may be regarded as unscientific by those working in linguistics. Traditional Western grammars classify words into parts of speech. They describe the patterns for word inflection, and the rules of syntax by whic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Falsifiability
Falsifiability (or refutability) is a deductive standard of evaluation of scientific theories and hypotheses, introduced by the Philosophy of science, philosopher of science Karl Popper in his book ''The Logic of Scientific Discovery'' (1934). A Scientific theory, theory or hypothesis is falsifiable if it can be logically contradicted by an empirical test. Popper emphasized the asymmetry created by the relation of a universal law with basic observation statements and contrasted falsifiability to the intuitively similar concept of Verifiability (science), ''verifiability'' that was then current in logical positivism. He argued that the only way to verify a claim such as "All swans are white" would be if one could theoretically observe all swans, which is not possible. On the other hand, the falsifiability requirement for an anomalous instance, such as the observation of a single black swan, is theoretically reasonable and sufficient to logically falsify the claim. Popper propo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Linguistic Prescriptivism
Linguistic prescription is the establishment of rules defining publicly preferred usage of language, including rules of spelling, pronunciation, vocabulary, grammar, etc. Linguistic prescriptivism may aim to establish a standard language, teach what a particular society or sector of a society perceives as a correct or proper form, or advise on effective and stylistically apt communication. If usage preferences are conservative, prescription might appear resistant to language change; if radical, it may produce neologisms. Such prescriptions may be motivated by consistency (making a language simpler or more logical); rhetorical effectiveness; tradition; aesthetics or personal preferences; linguistic purism or nationalism (i.e. removing foreign influences); or to avoid causing offense (etiquette or political correctness). Prescriptive approaches to language are often contrasted with the descriptive approach of academic linguistics, which observes and records how language is actual ...

Linguistic Description
In the study of language, description or descriptive linguistics is the work of objectively analyzing and describing how language is actually used (or how it was used in the past) by a speech community. François & Ponsonnet (2013). All academic research in linguistics is descriptive; like all other scientific disciplines, it aims to describe reality, without the bias of preconceived ideas about how it ought to be. Modern descriptive linguistics is based on a structural approach to language, as exemplified in the work of Leonard Bloomfield and others. This type of linguistics utilizes different methods in order to describe a language such as basic data collection, and different types of elicitation methods. Descriptive versus prescriptive linguistics Linguistic description, as used in academic and professional linguistics, is often contrasted with linguistic prescription, — entry for "Descriptivism and prescriptivism" quotation: "Contrasting terms in linguistics." (p.286) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cognitive Science
Cognitive science is the interdisciplinary, scientific study of the mind and its processes. It examines the nature, the tasks, and the functions of cognition (in a broad sense). Mental faculties of concern to cognitive scientists include perception, memory, attention, reasoning, language, and emotion. To understand these faculties, cognitive scientists borrow from fields such as psychology, economics, artificial intelligence, neuroscience, linguistics, and anthropology.Thagard, PaulCognitive Science, ''The Stanford Encyclopedia of Philosophy'' (Fall 2008 Edition), Edward N. Zalta (ed.). The typical analysis of cognitive science spans many levels of organization, from learning and decision-making to logic and planning; from neuron, neural circuitry to modular brain organization. One of the fundamental concepts of cognitive science is that "thinking can best be understood in terms of representational structures in the mind and computational procedures that operate on those structur ...

Tree-adjoining Grammar
Tree-adjoining grammar (TAG) is a grammar formalism defined by Aravind Joshi. Tree-adjoining grammars are somewhat similar to context-free grammars, but the elementary unit of rewriting is the tree rather than the symbol. Whereas context-free grammars have rules for rewriting symbols as strings of other symbols, tree-adjoining grammars have rules for rewriting the nodes of trees as other trees (see tree (graph theory) and tree (data structure)). History TAG originated in investigations by Joshi and his students into the family of adjunction grammars (AG), the "string grammar" of Zellig Harris. AGs handle exocentric properties of language in a natural and effective way, but do not have a good characterization of endocentric constructions; the converse is true of rewrite grammars, or phrase-structure grammar (PSG). In 1969, Joshi introduced a family of grammars that exploits this complementarity by mixing the two types of rules. A few very simple rewrite rules suffice to ge ...
